Do you have any devices to suggest ?

If you need more sensitivity at 10 GHz, try using an 8-12 GHz LNA with about a 20dB gain.? The 8-12 GHz LNA will give you additional sensitivity and also provide some preselection. Herb

You would gain nothing. The older FW does not have a correction table for the mode above 5.3 GHz so it will display incorrect power levels. -- Designer of the tinySA For more info go to

So, if I downgrade the firmware to a version older than 1.4-125, can I lower the noise floor and gain several dBm in sensitivity around 10 GHz, or as I imagine, the real values are those of the

I have seen that the size of the images are reduced after sending the message and some are unreadable. The output of the commands can be better read in these images: correction ultra (

Hi Erik, This is 0 to 10GHz scan done on my TinySA Ultra with firmware 1.4-156 without antenna connected: This is 0 to 10GHz scan done with the antenna connected: This is the output of the "

See: https://tinysa.org/wiki/pmwiki.php?n=Main.USBInterface Here a small set of python examples to control the tinySA Ultra, these should easily translate to MatLab using the serial port

Hi Developer Can I remote control the TinySa Ultra by my own programming SW base on Matlab? Because I can not find any file to describe the individual commands and programming example, for example,

Thanks for the input, can I ask where your experience comes from, so I can say It wasn't just a guy on the internet, lol Two words will do if that's cool............ cheers

This looks like a normal 1.7 GHz LTE signal to me. The digital modulation in any of the higher-order LTE QAM modes shows up as a mostly flat spectrum within its defined channel

In firmware v ersion V1.4125 Erik extended the level correction tables to 10GHz.? Prior to version V1.4125 both the noise floor and the measured levels above 6GHz were uncorrected levels and mainly

Calling people with experience of Mobile data transmission, does this look like something you're familiar with? I was recording overnight and picked this up, to my untrained eye it looks very digital

Can you post a 0 to 10GHz scan to see if the noise floor changes over frequency as determined by the internal calibration table Or you can connect via serial over USB and post the output of these two

In May 2023 I purchased a TinySA Ultra from Zeenko store on AliExpress, then upgraded to firmware 1.4-99 and now to version 1.4-156. Looking at some videos and posts of users testing the TinySA Ultra

Hi Luca, Did you do a Clear Config then a Calibration before the Self Test? HTH...Bob VK2ZRE

This is not a fail but a "critical" which can be ignored. This is a possible LNA failure. Restart, Connect in selftest configuration, enable the 30 MHz cal output and enable the LNA and post a photo

Hi, I've just updated firmware to v1.4-159 on both my tinySA and my Ultra and both failed self test after that. TinySA reported "Test 7: StopBand Critical" Ultra failed both Test 10 and 14, both

Lets close this topic as everything has been said. -- Designer of the tinySA For more info go to https://tinysa.org/wiki/

18.87dBm is just over 15mW, however, the OP wants to drive an amplifier with the 15mW that has a typical o/p of +38dBm, over 6W, which certainly is not legal!! Regards Jeff

As designed by the factory, wireless microphonea are indeed allowed in this band, if they are FCC type accepted. Indeed this system the OP is talking about is allowed secondary service under part 15,
