Re: Measuring Power at 76 GHz
Jens,toggle quoted messageShow quoted text
I use the Q8486A (33-50GHz) head with a waveguide taper, for measuring 76GHz. That reads high by approximately 7dB, when compared to a calibrated HP mixer. If you use a single diode mixer, the LO level can be high. So with the power head you are reading a total of LO and both sidebands, plus any other harmonics not cut off by the waveguide. The 40GHz head will be different, but not necessarily reading low.
