[PSES] FCC DTS Measurement Procedure - FCC KDB 558074 - Radiated Spurious Emission

[Grace Lin]

Dear Members,

For digital transmission system (DTS), is it acceptable for radiated
emission measurement (EUT is configured to transmit continuously)  taken
with Peak detector for peak data and use duty cycle correction factor
(DCCF) to obtain average data (instead of using RMS detector to obtain
average data)?



Thank you very much for your time and we look forward to your guidance.


Best regards,

Grace Lin

[PSES] Kikusui TOS3200 Leakage Current Meter

[Peter Tarver]

Hello.

I am using a Kikusui TOS3200 to measure touch current for a 61010-1 application.

The product is double-insulated and has accessible USB port connector shells 
connected to the secondary circuit reference.

When using the TOS3200 in meter mode (using the two external meter leads), I 
obtain different results than if I measure using the faceplate 5-15R outlet and 
one external meter lead. For each test, I'm using the same measurement networks 
when attempting to correlate the results.

When using the outlet, the meter lead connects to the USB shell.

When in meter mode, I am connecting one lead to the USB connector shell and one 
lead to the power conductor of interest.

Has anyone experienced this with either the TOS3200 or other leakage/touch 
current meters?

FWIW, the manual does not indicate any special considerations are needed when 
using meter mode.

The instrument is in good condition and went through a calibration verification 
in AUG2016.

The currents are within "Measurement range setting Range 1," but the meter is 
set in auto range mode. I plan some additional experiments using defined 
ranges, rather than auto in the next day or so.
