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.
Sweep Points/Span is < minimum. Results
may be inaccurate.
The sweep point to span ratio is below the minimum required to
ensure the bucket ratio is large enough to test DVB-T masks
Trace file saved. The trace saving operation was successful.
High-pass and Low-pass filters set to
OFF
Turning on any band pass filter will turn off high-pass and
low-pass filters.
High-pass filter set to OFF Turning on any band pass filter will turn off high-pass filters.
Low-pass filter set to OFF Turning on any band pass filter will turn off low-pass filters.
Band-pass filter set to OFF Turning on any high-pass or low-pass filter will turn off band pass
filters.
Cal Cancelled; Calibration data cleared User has cancelled the cal either directly or indirectly by changing
the setup parameters. The current cal data has been erased.
Perform a new user cal to obtain calibrated results again.
Use Gate View Sweep Time in the Gate
menu.
When in Gate View you use Gate View Sweep Time, rather than
Sweep Time, to control the Gate View window
Allowable Center Frequency exceeded for
the current span
When rotating the knob or step up/down keys to change the
Center frequency, the value of the Span is kept constant.
Therefore, the center frequency is limited by the frequency range
of the instrument.
Allowable Span exceeded for the current
center frequency
When rotating the knob or step up/down keys to change the Span,
the value of the Center frequency is kept constant. Therefore, the
span is limited by the frequency range of the instrument.
Allowable Start Frequency exceeded for
the current span
When rotating the knob or step up/down keys to change the Start
frequency, the value of the Span is kept constant. Therefore, the
start frequency is limited by the frequency range of the instrument.
Allowable Stop frequency exceeded for
the current span
When rotating the knob or step up/down keys to change the Stop
frequency, the value of the Span is kept constant. Therefore, the
stop frequency is limited by the frequency range of the instrument.
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
No spurs have been found 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.
