Some users reported that nothing was displayed on the graph when using tinySA (basic). The issue was caused by WinSpectrum's default scan setting of 450 points, which the tinySA (basic) does not

No this is not just an attenuator. It is a limiter with silicon devices. You can buy limiter diodes and build several yourself if you don't want to pay $63 for good insurance. That's your decision.

So help me understand... This is basically an attenuator, but only for signals above a certain threshold, letting weaker ones through without attenuating them? Matthew KD6KVH

Below is an update on the schedule of speakers and presentations for the Southeastern VHF Society Conference. The conference will be held at the Quality Inn at Exit #4 in Clarksville, TN April 4-5,

1) Yes, for isolation, both ports should have a non-reactive 50-ohm resistor installed. 2) It's excellent insurance to install the following on each port. From MiniCircuits:

Hello Erik! To do a proper ISOLATION calibration you need 2 load stubs. The nanoVNA only comes with one??? Matthew KD6KVH

Seems to work pretty good like you said Thank you so much!

To do pure power measurement at a known transmit frequency (or small range of frequencies) it may be better to switch to zero span mode and set the RBW to 850 kHz. This will convert the tinySA into a

Hello there, I am having some strange behaviors between rx and tx in my personal project and have thought of using tinysa to better monitor what is going on. The use will be for short/medium range so

For meticulous as I am, About the 3rd time I calibrated my NanoVNA 2-3 years ago.. Calibration was funky and the supplied 50 ohm load was, I recall OPEN... Fortunately AMAZON? solved that with a pair

Some people like to have a spare or backup set of calibration kits in case one gets lost or misplaced. Myself, I have a set for my NanoVNA H and a set for my H4. Both NanoVNAs are in separate cases

That was my thought. It would be ideal to have two 50 ohm resistors to calibrate the isolation setting, but not really needed from my experience. Back to TinySA

Absolutely no need to buy a second calibration kit. The kit supplied with the nanoVNA is good -- Designer of the tinySA For more info go to https://tinysa.org/wiki

What is the second calibration kit for the NanoVNA for? Or what kit should I buy off of amazon to do it? I have the calibration kit that came with the NanoVNA, can you post a link to the one I should

For the VNA you need a second calibration kit, to get a second 50 Ohm load and barrel connector to do the ISOLATION step of the calibration process -- for S21 type tests. Amazon has inexpensive

Also some higher-power attenuators. I have some 5W, 10W and one 50 watt attenuator (that one is 30 dB). If you're concerned about wearing out the connectors on the TinySA, just get a few

The main things I think of are a set of attenuators and some in-between adaptors for the various connector types. I have 2 watt SMA attenuators (male on one end, female on the other ehd) covering 1 to

I'm new here and new to my TinySA Ultra and NanoVNA. Trying to keep it affordable, I'm just trying to figure out what accessories I should buy first and which ones I should still buy but can wait

Found the solution on the community.st.com forum: dfu-util -s 0:force:unprotect -a 0 -D firmware.bin

I am facing the same issue on TinySA Ultra - on my PC (Win11) it exits from DFU mode as soon as I connect it. On linux it stays in DFU, but I can't update the FW - getting the same error as you
