Torque on SMA connectors is very important and touchy. The torque applied to SMA connectors seems to vary between 5 in-lbs and 9 in-lbs depending on where you look. Pasternack sells a really pricey

Now I opened it, and it turns out that R98 isn't present. Since I had it open, I measured battery current while off: It's 0.87mA. At this current it takes two months to totally discharge the initially

I will do that. So far I have been too lazy! ;-)

I found usb-c to usb cable at a dollar store. 0ops … now its a dollar and a quarter store. Chuck KF8TI

The USB cable for my NanoVNA got misplaced when I moved. Anyone know where I can get a replacement for it

I have performed the above recommendations and in addition I tried to connect the NanoVNA ro a separate laptop which uses Windows 7. It will not automatically install in Windows 7 as it did not

I did some -H4 measurements of a 75 ohm 0805 SMD resistor using a SMA test jig I built (picture below). I find it works well up to several hundred MHz. Attached are some plots using NanoVNA Saver in

Sure. Select a marker from the marker menu, then set Marker / Search Minimum, and then select Marker / tracking. It will find the bottom of the trace on each sweep. The numerical values are at the

Hi - I do this with the NanoSaver PC software, but is there a firmware version or setting that will allow me to run a range scan (without having the VNA connected to the PC) and display the current

The quality of your measurements at S-band will depend a lot upon the quality of your calibration standards and the accuracy of their definitions. I use a 6GHz LibreVNA for my consulting work so I

I use this combination also but my indoor model is the H4. I actually have two sets and affixed UHF to SMA and BNC to SMA adapters since I use these connectors. Make sure you get the -F hardware

After building and measuring a few more DL devices, the ones using large SMD resistors are "nosier" than metal/carbon film through-hole versions. Even so, Return Loss/Impedance is MUCH better with the

Hello Manfred, removing R98 on the liteVNA62 will solve the problem of power consumption at shutdown.

I also bought a LiteVNA, the small one (2.8" screen), for UHF and above. I use it mainly to measure antennas, lines, filters, etc, on the 5.7GHz band. It works fine. My only complaint about the

NanoVNA-F for outdoors use, -H for indoors. The little 2.8 inch -H is quite inexpensive, and also works well with PC software (NanoVNA-Saver and NanoVNA-APP), showing on a larger screen. With the PC

LiteVNA 64 - is sensational, I can recommend it with a clear conscience 73, Sebastian

Hello Siegfried, The Deepelec NanoVNA-F uses slightly different electrical design to the original "edy555" NanoVNA and so does not use the original PCB layout. So there are no "unused" crystal pads.

Your chip looks like a 5351 since it has the right markings and was produced in 2000. See description below. The chips are now readily available again with stock at DigiKey and Mouser. It is a 10 pin

David, Thanks for the info! I am investigating the LiteVNA 64. Ed, K0KC
