Re: VNA Feature Request

Hi Mark,
it would also be nice to have two tiled screen with horizontal alignment of the two S-Parameter plots.
By now they are vertical alligned. I have attached a screenshot with two smith chart ( very small as mentioned before ) that shows the problem.

Re: Measure High Power Devices

HI Gerry, this is not a time critical discussion... I just mentioned that if you close the utility window a sweep plan will not stop. It looks like it continues even so the data cannot be used since the utility window was closed. I can imagine technical reasons that it is not possible to interrupt a...

Re: Measure High Power Devices

Hi Gerry,

I can understand that one sweep is not interruptible. But I cannot understand that a sweep plan that consists of many single sweeps cannot be interrupted. It lokks like that this is still running even when you close the window.

Measure High Power Devices

I have an amplifier that can deliver maximum out power of about 36 dBm. It has a gain of about 45 dB. I do ordinary VNA measurements with an input level of -17 dBm and an output attenuator of 20 dB. So it is on my side not to overload the receiver port... What about the Gain Compression Utility ? Ma...

Hi Neil,

I have used the original files from Github. Nothing changed.
I will send you the DefCal.cal by mail to support.

Re: PicoVNA Vector Network Analyzer Toolbox

Sounds great.

So you mean that the Version 2.11.0.16 enables actual Matlab Version to interface with it ?
It would be nice to read this in the release notes and also on GitHub.

Re: PicoVNA Vector Network Analyzer Toolbox

Seams to be unusable. Actual versions of Matlab are only 64 bit. Latest version that can be used is 2015b. Actual version is 2018b. When will you support the 64bit Versions of Matlab ?

VNA Feature Request

It would be very nice to have an additional 3 tiled screen. If you use 2 or 4 tiled screens and have a Smith Chart in one of them, the Smith chart is very tiny. Espacially if you are doing 1 port measurements it would be nice to have two logmag screens on the left and one bigger Smith chart in the m...
