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 freq's for an LSB or
DSB (for DSB measurements the setup uses LSB values) downconverter setup. Use
the graph icon on the DUT setup form to clarify the setup required.
Logarithmic scaling cannot be used for time domain sweeps (0 Hz span).
The demodulated burst type has not been found in the originally demodulated slot
location within the frame.
The frequency context parameter has been changed either by the user or the
system. The frequency menu will now contain the frequencies for the new context.
No action required.
Turning on any band pass filter will turn off high-pass and low-pass filters.
Turning on any band pass filter will turn off high-pass filters.
The setup frequencies break the rules for an upconverter measurement. The
measurement will still run, but check setup frequencies are correct before
continuing. The IF fixed freq should be greater than the LO Stop freq for a USB
upconverter swept LO setup. Use the graph icon on the DUT setup form to clarify
the setup required.

The instrument's input is set to internal (the internal amplitude reference signal). So
any signals connected to the front/rear panel inputs cannot be measured.
