Yes, but I was uncertain if the maximum pulse I can get out of the high output (only -25dBm, 30miliVolt) is?sufficient for a modern scope to trigger. Would it? --

This is a very good point. I cringe whenever I see a device pin connected to the outside world without any protection. Here is a good video on the topic: https://youtu.be/GshgZE5ANQ0 73 -Jim NU0C

Erik, Have you considered sending a trigger pulse on the High output at the start of every sweep on the Low output? By doing this the scope could be set to Ext. trigger and the A channel of the scope

The release has been update by adding the console command sweep_voltage {0-3.3} It sets the full sweep voltage output between zero and 3.3Volt. Don't forget to do a saveconfig after changing the

A simple band pass filter that cuts of frequencies below UHF and above UHF will reduce overload from out of band signals. I found the use of of the available CATV high and low pass filters will do the

Hello This new release shows no random fails on selftest 10 any more. Sven Hegewisch

New FW released Version V1.1-91 Changes: - Added output of sweep voltage(0-3.3V) For those brave enough to do a small modification I added a sweep voltage output. The sweep voltage output can be used

The NRSC mask seems to fit the capabilities of the tinySA and the peak-hold is available. The two problems I see are the 300Hz resolution bandwidth that is prescribed but I'm not sure if that is a

It may be possible to update the FW using the tinySA-App (button with the two triangles pointing up). Did you try? Do not forget to put the tinySA in DFU mode. Be careful and only try when you must

The high input is more sensitive but also easier overloaded with signals outside the selected frequency range. The low input has much better rejection of signals outside the selected frequency range.

Has anyone tried using the TinySA for AM broadcast NRSC test measurements? The idea is to eliminate heavy, bulky power consuming equipment in remote locations.

The tinySA-App seems to work ok.? So USB comms appear to be working.? Just when uploading firmware it always finishes with an error. By shortening the St-Link pins I can leave them soldered on. If

I have an over the air TV antenna "system", i.e. VHF/UHF outdoor antennas feeding a mast mounted preamp, then a distribution amplifier, etc.? The TinySA is a fantastic tool to troubleshoot the

This morning I tried to update to the current firmware via USB and got the white screen again. 100% failure rate via USB.? I guess future upgrades will have to be via ST-Link. Kind of a pain to

The UART is currently NOT enabled in any of the SW If you want to use something else than serial over USB (DFU mode) you will have to use an ST-Link with STM32CubeProgrammer and connect it to GND,

So, now, a 'original' tinySA from Zeenko Store is on it's way from China to me. Monday 22. Feb. Aliexpress should step in to finalize the dispute I have opened with the Toolbox-Store. Toolbox-Store

Looks good. Do test the switches as contacts may deteriorate over time and you may have to clean them. -- ------------------------------------------ For more info on the tinySA go to
