Has this issue with the SignalHound SA44B being unable to correctly measure power levels of OQPSK been resolved?
Does this issue exist on the SM200B?

We were never able to close the loop with this customer and determine why he was seeing a discrepancy with their measurements. In general the SA44B has some measurement quirks, but it is possible to measure power levels of OQPSK signals with the SA44B. This customer had very specific measurement requirements, which I believe were contributing to the issue.
In general, the BB60C and SM200 analyzers are better for wideband modulated signals.
