CW Mode Pulsing Issue


Isidro Berniol 2020/08/28 09:58

Hello,

today my new NanoVNA V2 arrived, sadly I realized afterwards that I have got a clone, but it isn't build that bad.
I think it's a clone, because the board looks litle different to the picture of the board in the official shop.

Nice to see the higher dynamic then my NanoVNA-f ( also a nice unit :-))

Now I have a litte problem, in CW mode there isn't a constant signal, I found out that the VNA will switch his ECAL for compensetion.

But I don't understand the sense at all. CW mode means to me the unit should deliver a constant cw signal like a generator, thats what I would expect the unit to do and what all the VNAs I had to play with also did.
When I only like to measure at a fixed frequency I could use zero span instead.

Is this a bug or a feature?

Will this be fixed in the near future?

Thank you very much.

Regards,

Isidro

I have the V2 version from Tindie, this question is discussed and solved in the forum https://groups.io/g/NanoVNAV2/topic/cw_pulses/76262045?p=,,,20,0,0,0::recentpostdate%2Fsticky,,,20,2,0,76262045 and downloading the modifing firmware works.

There´s any version for CW for PLUS4?

there is CW on mine. The issue is there is another one under CFG SWEEP. That one makes it constant to use as a signal gen.
Otherwise it is pulsing to do its measurements.

It does the same, with CFG SWEEP in CW it make pulsed wave, not CW
