Rainer, If you remove power from the bias-tee, the LNA no longer works. But it almost certainly does not short input to output, and if it did it would not do so without adding extra loads to

I believe the m stands for milli (1/1000). Mark *From:* Jim Lux ( jimlux@... ) *Sent:* Tuesday, October 6, 2020 9:44 AM *To:* [email protected] *Subject:* Re: [nanovna-users] Basic

if your LNA is one that has a relay to bypass it when it's off, then yes, turning off the power would be what you need.

Hi, I was thinking about this DC Blocks. If I understand correctly those DC Block block the DC current and without DC current my Low Noise Amplifier does not work, correct ? So if that is the case,

Very Nice piece of software - Thank you to OneOfEleven Granted that I've spent the last couple of days coming up to speed on the NanoVNA and the other PC apps for it before I found this a few hours

milli. so it's 0.697 ohms.

Won by the SMA'ers evidently, and rightfully so in this application. Most of my adult life has been spent working on radar systems, from 1 to 22 GHz. The determining factor in whether SMA or N

In that case, you will eventually want to use the NanoVNA on other antennas as well. It will be REALLY worthwhile to get a few connector adapters. I have gotten sets of UHF/PL259 and of BNC adapters

Thank you very much Christian. That was what I suspected, but wanted confirmation. Ed

"m" simply means "milli". I.e., 56.3 - j*0.697 ohms.

Hello all... I have a dipole that I ran a sweep on with NanoVNA Saver, and a NanoVNA-H. When looking at the complex impedance at the closest point to resonance ('0' reactance), I get numbers

Thank you Larry!

Great set of references. In addition to Dave's HP application note links, there are more here: http://hpmemoryproject.org/technics/bench/8510/bench_8510_home.htm . The 8510 documentation is

Yes, using binary data transfer, USB-CDC is no problem at all. But this is a completely restarted project. Jan developed this project completely independently. We can consider compatibility in the

First let me add that the load standard does not have to be ideal, it only has to be known. You can reformulate the SOL calibration to account for a non-ideal load. The same of course applies to short

As a rough guide, you need the load to have a return loss of 10 dB higher than what you are measuring to get a measurement uncertainty of 1 dB. So a 30 dB return loss load will enable measurement of

Hey Alan, Thanks, I got it downloaded and installed. This appears to be for seeing uncertainty given a specific model VNA and cal kit. It's quite interesting but if I had my own cal kit, how might I
