The power sensors report their error states to the R&S NRX. The error states depend
on the power sensor type. Described notifications:
2001 - sensor maximum allowed count
.......................................................................493
2003 - sensor settings conflict
.....................................................................................493
...........................................................................................493
............................................................................................. 494
............................................................................................... 494
2008 - sensor protocol minor mismatch
