Herb,
The commands you recognize are the same as the nanoVNA. The returned data per trace is only one number as the power measurement is scalar and not a vector
Next to the nanoVNA level commands there are a number of low level commands. These can be used to scan any amount of points in one scan.
If you enable the tinySA.exe output logging you will see the commands used.
tinySA specific commands:
?
mode low|high input|output
spur on|off
attenuate 0..31|auto
rbw 2..600|auto
if {freq}? ? ? ? ? ? ? ? ? ? Sets or shows the first IF
v 0|1? ? ? ? ? ? ? ? ? ? ? ? Selects the LO for next commands. v0 is for setting the frequency of the RX SI4432 (effectively the IF), v1 for setting the LO of the first mixer.
selftest 1..3
x addr {value}? ? ? ? ? ? ? ?Sets of reads SI4432 registers, addr and value use hex without 0x
o 240000000...960000000? ? ? Sets the frequency of the SI4432 in Hz
a 240000000...960000000? ? ? Sets start of a scan in Hz
b 240000000...960000000? ? ? Sets stop of a scan in Hz
s 100...1000000? ? ? ? ? ? ? Sets the number of points to scan
m? ? ? ? ? ? ? ? ? ? ? ? ? ? Perform sweep en return RSSI
The command set will change
