LO Fixed freq should be
greater than RF Stop freq
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
LO Start freq should be
greater than IF Fixed
freq
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

Low-pass filter set to
OFF
Turning on any band pass filter will turn off low-pass filters
No spurs have been found You 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
Preparing Calculation…
Preselector is centered The preselector has been successfully centered
Preselector not used in
this frequency range.
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

Probe connected, no probe
cal; using cable cal
data; <port>; <probe>
A probe has been connected and no probe calibration data is available. The latest
cable calibration data will be used
Probe disconnected,

A probe has been disconnected, calibration data reverting to the last cable
calibration data
Reading SNS data… The Keysight Smart Noise Source has been connected and the application is
