just tried to do also some dynamic range measurements

two HP 8640 Generators (out +20dBm) attenuated to 0dBm into
an 6dB coupler attenuated to -10 dBm into an stepp-attenuator

done on 20meter with 4pole 500Hz filter
IMD with pre -140 dBm
IMD no pre -134 dBm

dynamic range no pre
spacing IMD-Level Dynamic
20 kHz -31 dBm 103 dB
5 kHz -31 dBm 103 dB
2 kHz -34 dBm 100 dB
