Description/Correction Information
The setup frequencies break the rules for a downconverter measurement.
The measurement will still run, but check setup frequencies are correct
before continuing. The LO fixed freq should be greater than the RF Stop
freq's for an LSB or DSB (for DSB measurements the setup uses LSB
values) downconverter fixed LO setup. Use the graph icon on the DUT
setup form to clarify the setup required.
The setup frequencies break the rules for an upconverter measurement.
The measurement will still run, but check setup frequencies are correct
before continuing. The LO Start freq should be greater than the IF fixed
freq for an LSB upconverter swept LO setup. Use the graph icon on the
DUT setup form to clarify the setup required.

Turning on any band pass filter will turn off low-pass filters.
You has started a measurement in examine meas type in single or
continual sweep mode, or full meas type in single sweep mode, but no
spurs were found.
The preselector has been successfully centered
You cannot center or adjust the preselector because it is not used at all at
the current marker frequency or between the current start and stop
frequencies
A probe has been connected, calibration data is being reapplied
A probe has been connected and no probe calibration data is available.
The latest cable calibration data will be used
A probe has been disconnected, calibration data reverting to the last cable
calibration data
