Good point Wendy, I always control my Equipment from Compliance 5, so I have
never used the SW that comes with it.
Cheers,

Do ask for a demo unit and ensure that the emissions SW that you are using is
able to control it.
By the way I'm using the PMM receiver up to 3GHz with TDK RFS SW. You would
probably want to consider the 6GHz option. PMM is not a spectrum, hence if you

The last time I checked you couldn't certify anything that had a LAN
port on it, but things could have changed since this spring. Something about

HI Ken,
excuse my nievity here, but I need help understanding this.
A cable is only its characteristic impedance when fed and terminated in
matching impedance. That's why I said non-perfect impedance of the cable.
So, since the antenna output impedance is all over the place, you can't say

Most mixers are a poor match to 50 Ohms, and the manufacturer's instructions
will generally advise insertion of 10 dB between mixer and cable for that
reason. Of course, their noise figure or noise floor specification is based
on 0 dB attenuation. Connecting the mixer directly to the antenna

I have worked in the past with ADS-37 procurements, and still do, to a limited
degree. If one calculates the peak field intensities associated with an
average 200 V/m field using the pulse duty cycles of Table I, Part B, you get
the peak field intensities of Table I, Part B.
