Above 1GHz RF is like water. It flows? through every hole Hiding with the spur removal does not work as the spur removal removes spurs that do not actually exist but this 48MHz harmonic leakage is an

The TinySA doesn't use the ADF4350, it uses a couple of Si4432's.

Regarding ADF4351, would the Tninsa perform better with these rather than adf4350? Steve L ? G7PSZ

Now the 64,000 dollar question. What could be done to suppress them? Either hide them with software tricks, such as the spur-removal option, but that might leave “holes” in the spectrum, or

Yes the unit certainly has limitations, though for the price is not to bad really. Here's a -4dBm carrier from an ADF4351 at 50MHz. The TinySA shows a wide flat top and noise floor of only 45dB down

Done, The 4.8MHz is indeed present.

Erik, On my tinySA there also appears to be a sub-harmonic of the 48MHz clk at 4.8MHz.? Possibly a divide by 10 output? LOW and HIGH INPUTS terminated in 50ohm loads. Your explanation and an

These are 48MHz harmonics generated by the MCU. For now all tinySA will show them at 48, 96, 144, 192 and 240 MHz

Have I just been unlucky and got a bad unit, or does everyone suffer spurious signals on their TinySA? I see specific signals at 144.20MHz, 192.15MHz, and 240.19MHz. They are unstable, and wander

Yes, to be done

Very good. Could the firmware not have used the unique CPU serial number to create the device ID ?

You can measure the field strength of a source in dBuV/m if you change display units to dBuV and use a transducer calibrated in dB/m.? At a single frequency you can enter the tranducer factor (plus

The tinySA uses the same VID/PID as the NanoVNA so if you are writing a script or program to communicate with the tinySA, and both a NanoVNA and tinySA are connected to your computer at the same time,

I've already used mine for tracking power line noise t 300mhz using a small yagi for that band. With an untuned amplified .3M untuned HF loop I"ve tracked all sorts of items emitting significant

Besides the faster speed and unlimited points, the tinySA 'scanraw ' command transfers corrected data - unlike the similar command on the NanoVNA which transfers raw data and requires you to

Don't forget to check PC supplies, The worst I found was a PICO supply.

A very useful use of the TinySA is to track down sources of interference. The horrors of today's unfiltered unscreened (and often unsafe - we had one leave burn marks all up our lounge wall after it

Make sure you use the "scanraw" command i.s.o scan or sweep as scanraw can do unlimited points and sends data in binary, much faster

I think so.

Erik, Is that the only change in FW release v1.0-52? - Herb
