QUISK VNA

Serge
Hello

About HiQSDR-VNA mode
Just interesting:
- what really dynamic range in Transmission mode?
- how accurate is the VNA?
- best value for attenuator?

Thanks
Serge

Hello,

I am not sure what the dynamic range is.  And the accuracy depends mainly on the bridge, not on the software.  The attenuator should reduce the signal so that the ADC does not clip, but should be not be more than 10 or 20 dB beyond that.  The attenuator increases the accuracy because it helps establish a 50 ohm source impedance.
