I think that there might be an "ooops" in your analysis, of substracting 2 dB
from the limit, Richard.
A 6 dB variation in site attenuation could mean that a unit could be as much as
6 dB off the true reading. Of course, how can one measure the true reading?
Only by testing the unit on a site
The last word I heard, about February-ish, was that 1326 is being
held up by a disagreement over whether to incorporate the various
other parts, -10, -20, -30, into a single document, or keep it as
seperate documents. The general requirements section is supposedly
approved, but

Use a low-noise preamplifier or preselector with integral low noise
preamp. Companies such as ASI or chesapeake microwave can help you out.
You may want to start with the EMI receiver manufacturer.

I can't say from UL this or that, but I can tell you that such static
charges can exist on antennas. In my formative years I had a job in
a little CB/TV repair shop. On one especially windy/dusty morning I
walked in into the shop and I heard a loud SNAP occur every five or
six

Since this is a TV receiver, this is probably a circuit providing the antenna
discharge path required by section 43 of UL 1492, the standard for Audio-Visual
Products and Accessories.
The purpose is to bleed off the static charge which builds up on a typical TV
outdoor antenna, caus
System requirements for RE102
When performing the emission test RE102 according to MIL-STD-461/462D we
observe that the test system noise floor is at some frequencies just
below the most stringent limit (navy mobile and army). This is when we
use the bandwidths prescribed by the standard. We can l
In most of television receivers, the mains is isolated by an isolating
transformer. However, a RC-unit (i.e., two 5.6M ohm resistors in
series and connected parallel with a 0.022uF capacitor) is connected
between accessible parts and mains. What is the primary function of
this RC-unit?

I believe that this standard recently approved. The EN version will be
renumbered EN61326-1 and (according to ERA's Safety and EMC Newsletter)
should have been ratified by Cenelec in March. As for when it will be
published in the Official Journal (i.e. when it will become a standard

Does it have an EN number?
Does anyone have more information on this?
