in order to measure S11, you're needs to put 50 ohm load on LNA output and connect CH0 to LNA input. But first, make sure that your LNA can handle 0 dBm level! If it cannot, then there is no simple

hwalker, you can find adapter delay by connect unmatched terminator and check Group Delay screen. Of course it will also include delay of terminator, but with a series of measurement you can find

My $300 laptop has 1920 x 1080. Great for video etc but awful for running normal software on, what a crazy situation. The result is everything looks so tiny on the menus on 90% of the programs in

I have the same issue. But use another USB cable is sometimes better. If i push OK in the serialPort window, the port is recognized after a few attempts. But yes,it is not ideal.

The IP5303 chip turns on when the load is connected. Connect a 20-100 ohm resistor to terminal 8 and the GND, if switching on does not occur, replace IP5303.

Hi hwalker One comment to you BNC calibration test. Are you cal kit home made with three bulhead adaptors where 2x100 ohm SMD fitted to the centerpin as load and the open as well the load has the

Hi. I just bought the NanoVNA and want to make some tests on some LNAs.I have 2 SMA 20db Attenuators.How to setup the VNA & how S11 is important in the Tuning.Very thanks for answers.Regards Sid.

Edit: A warning. I was inspired to use another USB-C cable. Very strange is that with the supplied USB (black) cable the NanoVNA won't start connected to the PC. I did a test with a self-purchased

With all that new firmware, I now work a lot with the NanoVNA connected to the PC. With my modification in message # 967 I can start the NanoVNA with the placed switch on the IP5303. But once

Hi Andy, Hi, Andy, but your call also seemed familiar to me ;o) Yes, it's true, on 17.07.2017, in the morning at 04:30 I had a direct hit in my LF antenna. The antenna was disconnected but

Hi Hugen, this sounds very good! Are you looking at expanding the frequency/measurement range by a change of components as well? I'm happy to hear that you will stay consistent with the NanoVNA, but

Using the cho45’s web interface can use nanoVNA very good on the phone , I think this is a very good expansion screen scheme. I'm also trying a 3.5-inch LCD, maybe working with the STM32F303 to

This is the latest version of the edy555 that includes the TDR feature. I have modified the touchscreen calibration value before compiling and can be used directly with the 2.8-inch NanoVNA.

Done

Maybe it would fit better in the Firmware section? ;-) Good work! -- Rune / 5Q5R

I pulled edy555 release 0.1.1 and merged with my scan command extension /g/nanovna-users/files/NanoVNA%20PC%20Software Contains an experimental TDR functionality and 1500MHz as

Hi Andy, what errors are you seeing? -- Rune / 5Q5R [email protected]> wrote:

OK thanks for the feedback. I just wanted to know before I took the time to start testing, and possibly avoiding a learning curve. That would have been nice, because I can get vnaJ working fine on a
