Some very important observations in previous responses: 1 - to phase match, you don't need any particular value, just to make them the same for two cables 2 - at your target frequency, 5 degrees is

I installed the NanoVna App on my Android hoping to use it on my phone. My phone has a micro usb C socket with usb cable and I normally use this cable to connect to my PC to run NanoVNASave. I bought

Probably want end "open" so you get a reflection to measure the length, not terminated in 50 ohms.

THANK YOU! That helps tremendously.

Sorry...S11 delay. Cable terminated at one end only to allow for trimming.

The time didn't work the first time, and nothing has changed so it won't work again. Steve W5RRX Las Cruces, NM

They also make cool little length adjusters, at least in SMA. I've not seen one in N or UHF. They're not cheap, at least new, but they might show up surplus. Someone with a big box of adapters might

I think you got it correct (almost)... But you see a double delay cause its up and back down the cable... 26.8x2=53.6... And... You need them the same length / delay... If both are 52..or 53 does not

You're seeing the round trip time of ~50 ns What does the S21 me

S11 or S21 delay? On S11 2x delay (to cable end and back) On S21 1x delay (from one port to another(

I am having difficulty constructing a set of phase matched cables using my NanoVNA SAA-2N and the tutorial available at this link

Might I suggest that we continue to meet via Zoom on Monday evenings at 7 pm (EST) to share what we know about the VNA? I don’t see my talk as a “lecture” to record and watch. I’m not a VNA

Great, thanks. So you get the same results if the end is either open or shorted right? Reverse the cable and you can confirm where the break is. With a dummy load the cable length should read very

Hello Barry, Some of us in the NanoVNA community actually live outside continental USA. Not sure where your QTH is, but there is also a 5 hour time difference across the continental USA as well. It

One graph shows the Time Domain response of the cable attached to CH0 (port1). The other shows the approximate impedance magnitude |Z|. In the annotated Saver graph below I measured 3M of RG-316

I have been asked many times if these Zoom sessions on Nano VNA were recorded. NO. They were not recorded. The reason is simple: I wanted these sessions to be discussions, not lectures. Many folks

That is truly unfortunate. I am sure there are hundreds if not thousands of people including myself who would love to watch the presentation, but who got late notice or were not available at the time.

DiSlord, Correction: My tinySA shows it on the "VERSION" screen, while the NanoVNA does not. But this is also more a topic deep in the HW/FW - we should discuss this on GitHub. Are you still using

When you click on the TDR in Nanovsaver. The length of the cable is already indicated, which I presume is the physical length once you specify the coax type or VF. There are two plots on the graph,

Are there recordings?
