Marcus, Thank you for your response. The variation is on the order of 20%, although it changes from run to run. Power level from the generator is 10 mV through 40 dB of attenuation. The B200 is set for maximum gain (minimum attenuation) and is using sc8 format with peak=0.1. Thanks! On 4/21

What is the magnitude of the inconsistency? If you replace the signal generator with a 50 ohm terminator and increase the gain to near maximum, do you still see the inconsistency? What power level are you injecting from the signal generator. Sent from my iPhone > On Apr 21, 2021, at 12:27 AM,

Receive amplitude consistency

2021-04-20 Thread Mike
Hello, I'm hoping someone can shed some light on an apparent inconsistency issue I'm seeing with received I/Q amplitude. I have a B200 directly connected to an arbitrary waveform generator through an attenuator.  The generator is programmed to repeatedly send a fixed sequence of AM pulses at a se
