John, I guess you did see the tinySA wiki https://tinysa.org/wiki/pmwiki.php?n=Main.HomePage W.r.t the console commands I agree single letter commands are not easy to understand. Can I propose some

But wait, there's more! We are slowly but slowly implementing a complete serial command handler that when complete should allow you to do anything that you can do with the touch screen. We are also

If I can see clearly, the one-letter commands can be identified from the help made by John WA2ZFW. HBTE / Files / WA2FZW - M0WID ESP32 - ILI9341 Version of the TinySA folder.

Is clear, I was just too lazy to implement them yet, Triggering in the frequency domain depends a lot on the scan speed and may not be useful for narrow RBW scan (scanning is slow) The menu tree keeps

Greetings Erik, Looking good!!! This feature that would permit the screen capture of a sporadic burst IMHO could prove very useful. Terrific that you can do this for both time and frequency domain

Here they are: version reset freq saveconfig clearconfig data frequencies scan sweep test touchcal touchtest pause resume trace marker capture vbat vbat_offset help info color if attenuate rbw mode

Erik, I combined this request with another topic so you may have missed it.??When you get the time could you post what the "help" console command returns?? I'd?like to know what commands are

Here is a picture of the most simple setup The tinySA at the bottom right is doing the sweeping. Its tracking output from the high connector is connected to the LO port of a mixer. A generator at

Yes, that was the intention. You may use this setup: The external tracking mixer has three ports, LO, RF and IF. I'm assuming the IF port is connected to the diodes in the mixer so it can go down to

And then it occurred to me I can do the same trigger trick to pause a sweep once a signal above trigger level has been seen so here is the frequency scan of the 433MHz RF remote control. Not so clean

A rather basic trigger mechanism is implemented, If a signal is above a settable level a capture is done. Here a 433MHz RF remote control transmission I need to add some info on the horizontal time

Erik, Can a tracking generator be created using an external mixer and LPF driven by the tinySA LO?? I have a WJ 0.2-500MHz mixer and 300MHz LPF?on hand. I'm not clear what I.F.? is normally used to

Erik, Thanks for the replies.? When I have more than one serial device connected, the VID/PID helps my scripts automatically identify the device I want to communicate with.? The "tinySA" in the

Herb The VID/PID are identical to the nanoVNA (for now) The virtual serial port (when using it with windows) becomes? a COM port so no need for VID/PID there The info command output starts with

========================================================== Erik, While you are checking the documentation for the dc rating of the tinySA's? input ports, could you also see what the? VID/PID's are

Both ports are AC with multilayer SMD capacitors. I guess up to 25 Volt should not be a problem. Let me check when I'm back to where the documentation is.

Erik, You've already noted the input ports are limited to +10dBm max.? What is the DC limit of the input ports?? I assume the limit is de-rated to half the dc rating of the input port coupling

Sala, I have an SDRPlay RSP2 that I have used as a spectrum analyzer with the RSP-Spectrum-Analyzer software.? ?I would say that it is good for checks below 40 MHz, so good for tight in spurs

The cheap msi.sdr rsp1 clone is not good.

These are definitely interesting and the price is not overly high. Are SDRplay models good as general spectrum analyzers, Are there a lot of ghost lines and so on.
