Subject: [PSES] 6dB pad
Hi all,
I'm having a discussion with my colleague about the use of a fixed 6dB
attenuation pad at the input of the EMI receiver for radiated EMI in the range
, because nowadays the effects of these different detectors are
simulated in software.

This discussion not only applies to EMI testing, it also applies to
high-frequency and fast risetime pulse voltage measurements. A 6 dB (2x
voltage attenuation) or 10 dB (~3x voltage attenuation) in a 50-ohm system
which would otherwise be subject

Receiver vswr is specified with 10 dB attenuation because the mixer itself is
not 50 Ω.
Antenna vswr is usually best in the middle of the usable frequency range.
Worst case at the low end

Hi Ken and Tom
Thanks for your inputs. Yes, the 6 dB pad is at the receiver input, in addition
or not (depending on the signal level) to the built-in attenuator of the
receiver.
If the same 6dB pad is put at the antenna
-related uncertainty.
Unfortunately, you often cannot stand the desensitization of all the extra
attenuation.

If the same 6dB pad is put at the antenna output instead of receiver input,
it's at the other end of the cable

But he is placing the pad at the receiver input in lieu of an internally
selected 10 dB, not at the antenna's output port.
