Hello,
I had the same problem as Michelv – which was solved by firmware update (From 3 to 4).
However-
1. few of these spectrum analyzers have stopped working after a while.
2. One has even stopped working immediately after completing firmware update- its led doesn’t turn on and it’s not recognized by the computer/Spike software.
Furthermore, the device manager refreshes repeatedly while it’s connected to the computer.
What do you suggest? Are those problems familiar?
Looking forward for your assistance.
