Hi Gert,
Thanks for the reply. EN61000-6-2 calls EN61000-4-6, so I was
indirectly referencing that standard. I neglected to apply the
equations of section 6.4.1 as pointed out to me by Brian Kunde. My
thanks to him and to you for your offer.

Hi Sam,
I do not understand how an attenuator may alter the impedance level of
the CDN output so as
to create a high VSWR ? The measuring receiver has 50 Ohms in, and
adding an attenuator won't change that ?
Do you calibrate for impedance level, or for voltage transfer into
150 Ohms environment ?
BTW the standard you need is EN 61000-4-6 !
If you want to call me in the netherlands on +31 10 415 2426

Hi Group,
EN 61000-6-2 calls for severity level 3, or 10Vrms for conducted
disturbances. This equates to 37dBm which is 7dB higher than the upper
limit my receiver will handle (during calibration of the CDN). I've
tried to use an attenuator and compensate for it in my readings, but
this creates a high VSWR. Any ideas how to extend the dynamic range of
my receiver without causing high VSWR?
