I really don't know how equipment fares against -461E vs. -461C. I do know
that the "external" RE102 limit which is flat at 24 dBuV/m from 2 - 100 MHz

greatly relaxed or waived so that may be a wash. The new requirements

Hi Sandi,
We use a regular Panasonic VHS-C palmcorder @ 10V/m and have no problems with
it, besides some noise at certain frequencies mostly with AM. The auto focus
screws up on occasion, but with 20X optical zoom the picture is great and does
the job for ~$300.00.

Might I suggest putting a pin hole (minature) video camera in a metal box.

Sandi,
Another option for you if you have the capability is to buy a
commercial video camera and see if you can modify the system to improve the
immunity level of the camera system. You could have some immunity
improvement if you were able to shield the cable and somehow terminate

Hello Sandi,
Sensormatic makes various pan/tilt/zoom cameras (commonly referred to as a
"dome") for various CCTV applications. I used one of our dome products and
constructed a brass screen cylinder around the dome. Fastening the screen
to the skin of the shield was simple. We test to 10 V/m.
We enclosed our camera in screen mesh, but we had to verify that the enclosure
did not affect the calibration of the room. We test up to 10V/m with no
problems.

In general the two versions are very close where they overlap, but specific
answers must be on a case-by-case basis. Comparing CE03 with CE102 is
complex in terms of how the test item interacts with a LISN as opposed to a
a feedthrough capacitor, but the limits are very close. For RE102, there

There is one other point on the whole "to NRTL, or not" scenario.
