Yesterday Siglent published their latest firmware for the SSA3021X spectrum anlyser.
This device is notorious for three reasons:
- It is the most affordable spectrum analyser with the best price/performance ratio.
- It is hackable and Siglent doesn't seem to care too much.
- It not only features lots of great functionality and high refresh rate, it supports SCPI commands over USB and LAN, also.
I had to test it and mind you, telnet with root login is still possible and the hackabilty status remains the same. It is safe to upgrade from P08.01.
