Has anyone measured the common-mode impedance of clamp on ferrite located on a cable? As an adjunct, can you locate where the ferrite is on the cable? Thanks, Geoff, AB6BT

Yes, Jempi. Looks like. However, apparently the manufacturer removed the Version number - and credits to DisLord before shipping - hence blank version. After the FW upgrade from the files-section I

There is a new version from yesterday SAA-2N-D 211027.. just loaded, but not seen the difference yet... Have fun JP

I think they are all based on Dislords Firmware, but compiled for SAA-2N check this out

Of course the characters are not what is responding to touch but rather a small area of the touch screen that should correspond to where the characters are displayed, the correspondence being

At Christmas time, our veterinarian provides stylus/pens to her customers. I find one very useful on H4, but still have issues with characters in the top row being insensitive to finger touch or the

The video will give an indication of what noise to expect, particularly at higher frequencies; https://www.youtube.com/watch?v=Y1B7Znoa02Y

I'd also suggest you look over a narrower span. Dave - W?LEV -- *Dave - W?LEV* *Just Let Darwin Work*

If you're looking at s21 with a load on CH0 and CH1, 1/2 grid of noise at -70 dB isn't unusual.

Some good ideas. The 80 meter ham band is rather noisy now, so I believe that is certainly part of it. I put on a 50 ohm dummy load and the noise went down, but still is about one half of a grid on

Thank you Prem. Nice to see that you got the same device. Also mine is working fine. I think I will also update it to DiSlord fw soon. 73 Roberto IK2DID

Thank you Ted for the information. I think I will move to the fw you suggested soon. 73 Roberto IK2DID

I suggest that you try scanning a simple, known-good load - specifically, a good 50-ohm dummy load. Then, try a 100-ohm resistor, and then a 25-ohm resistor. Then, a small capacitor in series with

The tinySA has a much better and more robust signal generator and is worth every penny it costs and it's all also nice to have both devices.

Thank you madam! I'm new here... Tried your APP. Great! I wish you the best. 73, Prem VA3UMA

And this thread is germane to nanovana how? Also if you are to make claims, it is perhaps useful to have objective evidence to support the claims. -- 73, AB1PH Don Rolph

Don't thinl so. It prints a backup paper ballot that you have to check before entering...

What you have all failed to realize is that these supposedly "improved styli" have an internal bias feature that changes your vote in spite of the apparent vote you made. They will also induce a small

Have a look at the calibration menu and make sure there is a checkmark in the APPLY button. Also, make sure you calibrate the unit for the range you're using and save it to a specific memory slot.

I am new to VNA's, so it may be an operator error. I'm trying to use my NanoVNA, but the SWR waveform line varies about three decimal points, say 1.3to1 to 1.6 to 1 and looks like a jagged mess. It
