Re: [PSES] EN 300 330-1 H-field limit for 13.56MHz RFID

[Larry Stillings]

Piotr,
 
Have you also looked at EN 302 291-1 / -2 for the type of product you
describe in the header of your email? 
 
That would be the product specific standard for 13.56 MHz RFID, vs using the
generic standard EN 300 330-1 / - 2.

All,

What is the difference between transmitter radiated spectrum and transmitter
spurious domain emission ?
 
When I switch off transmitter to switch off transmitter radiated spectrum
than I also don't have transmitter spurious emission (when operating).
 
So when transmitter is operating what limit should I use:
in range 14.01MHz - 14.46 MHz : -10dBuA/m or -3.5dBuA/m
in range 14.46MHz - 30MHz : -16dBuA/m or -3.5dBuA/m

Re: [PSES] new EMC Directive

[Larry Stillings]

I received an email from NIST this morning. They (EUANB) have met again on
May 3rd in Dublin, Ireland.

The information I have is "the revision will be adopted in October 2013,
publication by the end of the year, and then they will prepare guidelines
for the transition period between the current and new directive".

That is essentially all of the information from the meeting minutes.

Re: [PSES] Korea standards in English

[Larry Stillings]

Grace,
 
So this begs the question. Why do we even have an MRA with Korea if all
these roadblocks are presented to USA labs? 
 
Personally, I think that if this is going to be the case, then no Korean
labs should be able to submit wireless products to the FCC, until Korea
loosens their requirements to the intent of the MRA. All countries that have
MRAs with the USA with the exception of Korea provide standards in English
and accept test reports in English.
 
Anyone else have some strong opinions on this. Because I have many other
issues with Korea, as in how they are able to change their standards every 1
to 3 months. I can't even keep my scope up to date with Korea because it
takes 6 months to become recognized and by that time they have changed the
dates of the standards.

David,
 
If you are not a testing lab offering testing services per Korean
regulations, it is easier for you to send your products to Korea, directly
or indirectly.  Korea requires test reports in Korean, confirmed by an NIST
official last year.
 
Korean test standards (EMC, Radio, Safety) are similar to the EU's.

Re: [PSES] iPhone 5 TxRx frequencies on 4g

Derek,
 
AT&T owns 700 MHz spectrum. So it will be the 706.5 to 713.5 MHz, 709 to 711
MHz. I am almost positive AT&T owns the 706.5 to 711 MHz space. The other
band that is certified on Apple devices is 782 MHz, 779.5 to 784.5 MHz, but
I am pretty sure that is Verizon.
 
Let me know if it matches up with your findings.

Re: [PSES] FCC maximum frequency measurement

[Larry Stillings]

John,

FCC (ANSI C63.4 / C63.10) specifies a 60 cm shielded loop antenna for
measuring radiated emissions from 9 kHz to 30 MHz (magnetic field, Rod
antennas to measure electric field are not allowed). 

The limit is written at 300 meters up to 490 kHz and 30 Meters from 490 kHz
to 30 MHz. However, since you tend to be in the magnetic field of the earth
we make the measurement at some near field distance of 10 or 3 meters using
40 dB/decade extrapolation factor.

Easier than debating.

How could you measure radiated emissions at 32 kHz, or in fact any

Re: [PSES] EU Telco Regulatory Requirements for xDSL or Voice products

[Larry Stillings]

Mark,
 
I also posed this question again at a meeting at NIST in 2009 / 2010
timeframe where European representatives we giving presentations. I was also
told that the European Union has no intention of publishing replacements for
the TBRs / CTRs in the form of EN standards to regulate wireline telecom.
Also since the R&TTE directive came out April 7th 2001 (I will not forget
this date), new technologies like ADSL2, ADSL2+, HDSL, HDSL2, VDSL were
still at the very least in the development stage. 
 
Therefore there are not even TBRs to fall back on for the new xDSL
technologies even if you wanted to make an attempt at something to show
compliance. 
 
There are ETSI standards and Broadband forum (DSL forum) standards as you
know, but the equipment cost for a test lab to acquire everything to perform
a full suite of tests to a set of standards that are not regulated /
required just is not going to happen. I know because I researched it
extensively and came to that very conclusion as I'm sure other tests labs
did.

Hi,

Do you find yourself wondering if all those years you have been doing the
right thing? Regarding this or that requirement, standard or procedure? You
think you know the answer, but doubting worm keep messing up your head,
bringing this very unsettling feeling of "oh (enter your own expletive)" ,
what if I am wrong? You hope 4-5 years ago you made a right decision, but
the reasons why seem to be eluding you at this moment? 

Product: ADSL Gateway. Regon: Eurpean Union. 
 
Are where any similar to FCC part 68 or A-tick regulations and processes in
EU for ADSL products? 

R&TTE Directive regulates ADSL products, but primarily from EMC and Safety
point of view. Under RTTE harmonized standards, there are no standards
regulating connection to public networks in EU. 

There are other (unrelated to RTTE) ETSI, TBR, IEC standards describing
connection requirements, but I can't find any standards products will be
required to comply with as part of CE Mark compliance assessment. Am I
missing something? Or are these standards part of RTTE but not harmonized? 

If PSTN connection requirements are not part of RTTE CE process, which
processes it falls under and how it gets regulated or enforced? 

In addition to CE, are where any other legal requirements to sell modems in
EU? 

I will be now bracing myself for feedback onslaught.

Thanks,

Mark

[PSES] Follow on to EN 61000-4-5 Surge Question, How is Voltage configur ed?

[Larry Stillings]

Firstly, thank you for those whom responded to my EN 61000-4-5 lightning
surge question last week

My follow on question, is how should the 230 VAC, 50 Hz Source be configured
for mains power.

Is using 230 VAC consisting of 115 volts from Line to ground, and 115 volts
from neutral (l2) to ground acceptable, or should the AC source be
configured to apply 230 VAC on Line to Ground, and Neutral or L2 configured
to be around 0 volts. 

Here in the USA we have two phases, although we call it single phase which
brings in 120 VAC on Line 1 and 120 VAC on Line 2 to provide 240 VAC, 60 Hz,
unless of course you have a building where one of the three phases is
tapped, but then my understanding is that is what is called 208 VAC, 60 Hz.

However, I mainly interested in how power is configured in Europe. From what
I read it is derived from either 415 3-Phase which gives 240 Volts on line,
or 380 3-Phase which gives 220 Volts on line, and 230 Volts on line was a
compromise between the two ?

[PSES] EN 61000-4-5 Lightning Surge Testing on AC Power

[Larry Stillings]

All,

What is the defined sequence of test voltages when performing testing to EN
61000-4-5 per a family standard that says use the procedure in EN 61000-4-5.


For example when doing a 2 kV Lines to Earth, 1 kV Line to Line test on AC
power, is it specified what steps must be used for this test. In other words
should I test at 500V, 1000V and 2000V for line to ground and 500V, 1000V
from line to line. Or should only 2000V Line to Ground and 1000V line to
line, or something different, like 500V, 1000V, 1500V, 2000V for example.

We have always done the three steps, but now looking through the 2006
edition of the standard, I cannot find where it states what steps should be
used. I know there a couple of family standards that say just the two
maximum voltages, but was just wondering? Any guidance or pointers is
appreciated.

Thanks in advance.

[PSES] Thermal Chamber 7 to 8 cu ft

[Larry Stillings]

Hello All,

I am looking for a thermal chamber 7 to 8 cu ft (21x24x24 or
24x24x24 inches interior dimension) that covers at least the range from -40
C to + 55 C. I do not need humidity. 

Any advice on manufacturer / reliability is appreciated.

I am in the New England area. 

New or lightly used (low hours). Single phase is preferred, but I do
have up to 30 Amps of 208 VAC 60 Hz 3 phase if needed. An upright unit on
wheels that can be rolled around and fit through a standard door opening
would be nice as well (34" wide x 78" high)

Please contact me off line if you prefer.

Thanks in advance.

[PSES] FCC - Frequency Range of Investigation for Intentional Radiator

[Larry Stillings]

Hello All,

I need clarification on the following. If a wireless device, in this
case a Zigbee transceiver uses a 16 MHz Oscillator, and other digital
circuitry in the device uses oscillators down to 18.432 kHz. 

Is the Radiated Frequency Range of Investigation from the
"transmitter circuitry" of 16 MHz and up to 25 GHz in this case, or from the
18.432 kHz frequency used in the digital circuitry? 

Just trying to determine if I need the customer to bring their unit
back, as initially they told me 16 MHz, and now I am finding three other
oscillators that are below the 16 MHz, but only used in the digital portion
of the circuitry.

This brings up an interesting point, because the FCC is very clear
that all frequency oscillators shall be listed in the block diagram and the
rules do not differentiate between unintentional (digital) and intentional
circuitry.

One other thing to add to this thread (as we just went through an audit) is
you will need to write a test procedure for the calibration (preferably with

Chris,

I've built several CDN's.  Repaired both CDN's and LISN's.   Never messed
with building an EM clamp.   Too much hassle IMO.

As far as calibration,  I try to calibrate as much as is practical "in
house".All the LISN's, ISN's, CDN's, cable loss, amplifier performance,
etc etc .  But in reality those "calibrations" are just "verifications".
To perform those verifications most people are lacking a network impedance
analyzer.  The test jigs or setups are easy to build or cheap to purchase.

Regarding an accrediting organization accepting the results,  you'll need a
process.  You can't go wrong by referencing CISPR 16 et. al.  in that
respect.   You'll need the verification data. AND, you'll need the
measurement uncertainty.
The last item, you can gather from your impedance analyzer accuracy
specifications (and calibration report) and the test jig VSWR & losses.

As for where you can send you in-house built test items,  most any ISO17025
test lab which calibrates EMC or similar devices can perform the
calibration.

  I'm aware of some people making their own CDN's and LISN's among
  other things and I have few questions about that.
  1) Has anyone tried to build their own EM Injection clamp?
  If so, were you able to find a ferrite supplier that sold
  half-ring cores?
  2) Is it acceptable to calibrate your own equipment?
  If so, how do accrediting bodies view this, and what
  documentation will they want to see?
  If not, does anyone have suggestions about where in the US I
  can send such homemade equipment for calibration (preferably Western
  US to save on shipping)?

I'm looking to purchase an EMI receiver for use in a 5 meter chamber. Does
anyone recommend a certain model? I would want one that has at least a
frequency range from 150kHz to 18GHz so one unit can be used for radiated and
conducted emission measurements.
 
I'm looking for a unit that can be calibrated by a local accredited
calibration lab. I believe all R&S receivers need to be sent to them for
calibration, which there would be risk and time involved in shipping.

Option B?  I thought I was the only one left with a cassette player in my

Not sure why anyone would bother with satellite radio, I find terrestrial AM
and FM broadcasts still have decent variety.

Dear XM Subscriber,

The FCC has notified XM that some of our older receiver models (generally,
those purchased before August, 2006) may not operate in the manner required
by the FCC and may cause interference to nearby FM radio users depending on
how the XM radio is installed or used.

The receiver models include the Roady2(r), SKYFi2(r), MyFi(r), Airware(r),
Tao, RoadyXT(r), Xpress(tm), Sportscaster, XR9-XCX9, Jensen JXR9, inno(r),
Helix(tm), and Nexus(r). Please note this notice does not apply to you if
your new car came installed with an XM receiver.

If you do have one or more of the receivers mentioned above and use it with
the wireless FM option or you have had the receiver professionally
installed, then we have several options available at no cost to you to
alleviate this possible interference. Please visit our website at
www.xmradio.com/fmmodinfo
  or call us
toll-free at 866-410-0096 to choose one of the following three options:

Option A:
We will send you ferrite beads to attach to your XM antenna and power
adaptor cables. (Ferrite beads are typically placed on the end of data
cables to reduce interference.)

Option B:
We will send you a replacement cassette adapter to use with your XM radio.
Only choose this option if your car radio has a cassette player.

Option C:
If your car does not have a cassette player, we will provide you with
ferrite beads and an installation kit, with hardware, to use in connection
with a professional installation of your radio along with a coupon
redeemable at no charge for professional installation.

Please visit the following website, www.xmradio.com/fmmodinfo
  for more
information and to select your option. If you do not have access to the
Internet, you may call 866-410-0096 for information on how to alleviate this
possible interference. To help expedite your order, please have your 8-digit
Radio ID (found on Channel 0 of your XM radio) and your FCC ID (found on the
back, the bottom, or under the battery of your XM radio), available when you
start this process.

Thank you for your attention to this matter.

Best Regards,
XM Management

Note - If you are using your XM radio's FM modulator to send the XM signal
to a home or car stereo, your radio will work best if you use an unused FM
frequency. Go to www.radio-locator.com/cgi-bin/vacant
  to find the
best FM frequencies to use in your area.

RE: FM Modulator Information

[Larry Stillings]

Patrick, All,

 I have XM. The problem is this. The units are in violation of FCC
rules. The output power in the FM band is limited to 250 dBuV/m at 3 Meters.
The unit's FM modulators output power got significantly increased after
testing and approval (of course they work really good). I have noticed that
when driving by cars with Sirius, that my station will fade out and all of
the sudden I will be listening to Howard Stern or whatever the other person
has on, in their car. I believe both Sirius and XM are being required by the
FCC to fix the non compliant radios, but not positive about this.
 More of an FYI, at my Camp I can have my Truck parked several
hundred feet away from the radio in the camp and get the ball game. I have
never measured mine, so I can't tell you if it is over powered or not, but I
suspect so.

RE: mw/mhz

[Larry Stillings]

Bob,
 I am assuming the standard you are talking about is for some sort of
low power broadband signal technology such as Bluetooth or Zigbee (because
of the low power). They are simply limiting the power to 3 mW in any 1 MHz
RBW/VBW. They are talking about making the measurement conducted mode on the
antenna port. If your device does not have an antenna port, then either a
"balun" to convert the impedance of your antenna to the 50 ohm input of the
spectrum analyzer maybe needed. There are sometimes provisions for making
the field strength measurement at 3 Meters (or other distance) and then
backwards determining the EIRP, but am not sure if this standard has that
provision.
 Hope that helps.

I am reading a Japanese standard for 2.4 GHz and it gives an "antenna power"
limit of 3mW/MHz (no antenna distance). Can someone help as to how this is
measured. I guess I don't understand the parameter being measured.
