TheoB:
tinySA Ultra could work fine. Depends on the accuracy (+/-2dB) and resolution (0.5dB) that you need. But it is capable of doing most things an expensive SA can do at a sub 200 dollar price point.
Example:
--- Code: ---cu -l /dev/ttyACM0 -s 19200
rbw 850
attenuate auto

This is just measuring 10 points with a whip antenna over USB. Max hold values over the entire band can also be retrieved using data. See https://tinysa.org/wiki/pmwiki.php?n=Main.USBInterface
