Hello, We just uploaded the currently available version of /F/L/O/S/S/ Maxima code: https://www.op4.eu/code/derdei20190923.7z as well as, the currently available version of its documentation:

Why is a rubidium standard at 10 kHz offset from the carrier at 10 MHz that noisy? Is the phase noise floor shown limited by the test set? Regards, Alan

Dave, 50 ohms to ground provides some protection, but often not enough. The standard human body model (HBM) for ESD testing is 1500 ohms in series with 100pF. The 1500 ohms is supposed to represent

Hello Rune, Again thank you for your perseverance with the nanoVNA PC Software you are bringing us all! It is very much appreciated. However I have a question regarding Calibration using your

Here is my RF-bridge measurement. I have blue RF-bridge with two installed jumpers. I'm using more standard RF bridge measurement method: 1) Open CAL menu and calibrate OPEN/SHORT/LOAD as usual 2)

Thanks for the Wiki links, they help understand what's going on

Thanks to the pointer on the specific edition on the antenna handbook, it was an easy find on ebay

Actually, you're right my previous screenshot was taken with no calibration for cable end plane. :) Previously I already performed this measurement with calibration for cable end and without and

This is the output from my NanoVNA as measured on an HP 8568B spectrum analyzer in Max Hold mode (50 Ohm input impedance). See attached photos. ~10 MHz -13 dBm ~100 MHz -9 dBm ~300 MHz -9.60 dBm ~600

Yes, I see the point being made now. I wonder if one of these mats could be used as a ground plane....

Rune, thank you very much for NanoVNA-Saver software. Your software is fantastic and you amaze me with all the improvements and features you continue to add. I really like that in all fit into my

Rudi, I totally agree with you than an applications note section would be a welcome addition to the "Files" category of this user group. The group is approaching 3000 messages and it is getting harder

I recently made a phase noise measurement with my HP 8568B analyzer and KE5FX excellent software. In the picture enclosed pink line is the nanoVNA plot. For reference the blue line is from my 10MHz

I did something similar a couple of years ago when type N "connector savers" were offered from China. These are male to female adapters. The first batch wasn't very useful about about 1.5 GHz. The

Hi Rune, Thanks. I really appreciate your help. -- Bryan, WA5VAH

Hi Bryan, this sounds easy to implement. I'll put it in the next version. :-) -- Rune / 5Q5R [email protected]> wrote:

Hi Rune, Thank you for this great software for the nanovna. I appreciate the 3 different markers which are available and you readout a lot of good information in the boxes to the left of the graphs.

I have one of those blue pcb return loss bridges from Aliexpress. Mine has the resistors correctly bridged. Directivity was measured: 10MHz 55dB (take this number with a grain of salt) 144MHz 39dB

Hi qrp.dd Incorrect, that is not a measurement of the CH1 input impedance. The cable between Ch0 and Ch1 create impedance transformation. You need to calibrate at the end of the test cable with a

Hello hwalker, Thank you very much for this useful application note. I very much welcome the fact that not only the measuring setup was described in detail, but also the measuring result was evaluated
