Thanks in Advance

doesn't factor in, cs06 in for series injection out or blocked by inductor
for parallel injection. call me for rationale, too complex for e-mail

Use the 10 uF caps:
1. For RS03 (since the caps are defining the powerline source Z).
2. For RS01 (but it won't make any difference).
3. For RS02 (not clear, but for consistency).
4. For CS06 AC leads, I use one 10 uF cap line-to-line, as shown in Figure
CS06-1 (as it lowers the voltage

When testing to mil 461a/b/c for airforce, emissions are done using 10uF
Capacitors in-line between the supply source and the unit under test (1
metre from the EUT). LISNs are used for army and have only been incorporated
for airforce equipments in 461d/e.

Hello,
Can anyone help me locate and download the FAA G2100(G) standard?

The digital data links that I regularly see have both an avalanche and a
jitter effect. By those totally subjective terms, I mean that once you get
to a point where the bit error rate (BER) goes from near zero to one percent
or so, you need very little more decrease in desired signal level to
That answered 90% of my unknowns. One last degree of freedom appears yet to
be uncontrolled. That is XMTR - RCVR separation. That would also have to
be fixed in order to get repeatable results. Is that the case?

Hi Ken,
Let me try to explain it better. The standard asks that you stop reducing
the signal strength one you cross the 25% threshold. I would imagine that it
would be very hard to get exactly 25% So for example if you got a 10 %
failure rate at one level then reduced the transmit signal
Hi David,
Two quick tidbits came to mind.
1. Many products with fans use thermostats or thermistors to control the
fans. In these products, the fans are only turned on when a certain
internal temperature is reached. So, there probably is a good justification
for measuring the noise at the

There is lots of useful info there, but I am not
sure that it gives you the full answer.

Dear All,
Palomar observatory will look forward to these blackouts (they have
generators). And my (battery-operated) scope will be ready. Always a good
side to others' misfortunes ...
