More attenuator testing of nominal 6GHz attenuators measured on 10GHz with the up-converter and the HP432 power meter :
- 10dB attenuators: 2 of them very close to the 10dB mark, the 3rd 9.5dB
- 20dB attenuators: All 3 within 0.5dB of the 20dB mark
- 30dB attenuators: All within 1.5dB of the 30dB mark
All this is good enough for my amateur radio lab. Part of the purpose is avoiding overdrive and/or destruction of input devices in sensitive microwave amplifiers, as well as getting estimated gain figures.
Not bad for relatively low cost attenuators, tested out-of-spec. Now some rough gain testing of amplifiers can be done. Those 6GHz attenuators are now all in the box with 10GHz test equipment.
