Hello, I come back to you because I need information on the interpretation of the nanovna curves. So I wanted to make a filter 4 poles from 2 filters 2 poles. By simulating on a model the 45MHZ

I've had the same question for some time, but never bothered to ask. I've always just calibrated directly on the VNA because of what NanoSaver says. Dave, can you please elaborate? Or anyone else?

yes, once you have calibrated in SAVER, you can store it on the laptop or PC for future use. Dave - W0LEV -- Dave - W?LEV

Hello, I've been using my Nano VNA as stand alone for a while and have recently started using the Nano VNA saver software for windows. I really like the software and find it very useful. I've been

Thanks Jim, Yeah, I was wondering about calibration. I've seen some conflicting info online. Here's what I did. Removed UUT. For Isolation, I connected 50 ohm standards to both CH0 and CH1. For

You should cal using the cal standards (i.e. a zero ohm thru), then make the measurement. If you're doing the cal with the UUT in the loop, who knows what you'll get. If you want to measure the Ch0

1/have you a copy of your soft ware 5.1.0 you need to look at bottom for plastic stuch under cove this caught me out

It's looking to me like my NanoVNA-H has an 87 ohm input impedance when I try to do a through measurement. Shouldn't it be 50? Here's how I came to that conclusion: I connected a 4.99k ohm resistor

I had a similar issue with an H4. A firmware upgrade fixed it, and improved the menu access, as well as the softkeys for setting frequencies.

Have you tried loosening the screws that hold the display in place? There may be a short-circuit underneath. Mike -

I recently found that I-PEX has some very explicit mating instructions. https://www.i-pex.com/sites/default/files/downloads/pdf/manual_mhf_i_lk_him-17020-01.pdf I realize the method is provided for

Perhaps something else is using COM10? The NanoVNA-Saver or whatever? David -- SatSignal Software - Quality software for you Web: https://www.satsignal.eu Email:

Roger, Thank you for your assistance and advice. I was able to actually communicate with the NanoVNA and pass along commands. It is quite an incredible tool! My soncere gratitude for the talent and

Attached is an annotated screenshot showing what some of the buttons do in NanoVNA app. It should be enough to get new users started. Roger

If you connect to a NanoVNA with a terminal program you need to set the baud rate to 115200 and no flow control. Roger

If you have problems... --------------- 1. There are not two wizards for the drivers. There are four drivers in the zip file - two for Win 8 and two for WIn7. You have to pick one of the four and

This topic is for NanoVNA app so please post Putty questions in your Putty thread so we don't hijack this topic. I will reply to your Putty inquiries there... Roger

I believe you are using WIN 7. The problem could be that you do not have the correct driver installed for Windows 7. Windows 10 has the correct driver for the NanoVNA ready to go (or update will

Try 115,200 for the baud rate. 73 Stan KM4HQE
