Error Messages
Error Messages in Alphabetical Order
INSUFFICIENT MEMORY FOR PRINT/PLOT
Error Number
There is not enough memory available for the print or plot function. Increase the
168
available memory by changing or eliminating a memory-intensive operation
such as reducing the number of points in the sweep.
INSUFFICIENT MEMORY, PWR MTR CAL OFF
Error Number
There is not enough memory space for the power meter calibration array.
154
Increase the available memory by clearing one or more save/recall registers, or
by reducing the number of points.
INVALID KEY
Error Number
You pressed an undefined softkey.
2
LIMIT TABLE EMPTY
Error Number
Limit lines cannot be turned on unless a limit table has been created. Refer to
205
the "Making Measurements" chapter of the user's guide for information on how
to create a limit table.
LIST MODE OFF: INVALID WITH LO FREQ
Error Number
List mode has been turned off in the frequency offset mode because it is
182
incompatible with your selected LO frequency.
LIST TABLE EMPTY
Error Number
The frequency list is empty. To implement list frequency mode, add segments to
9
the list table.
LOG SWEEP REQUIRES 2 OCTAVE MINIMUM SPAN
Error Number
A logarithmic sweep is only valid if the stop frequency is greater than four times
150
the start frequency. For frequency spans of less than two octaves, the sweep type
automatically reverts to linear sweep.
LOW PASS: FREQ LIMITS CHANGED
Information
The frequency domain data points must be harmonically related from dc to the
stop frequency. That is, stop = n × start, where n = number of points. If this
Message
condition is not true when a low pass mode (step or impulse) is selected and
transform is turned on, the analyzer resets the start and stop frequencies. The
stop frequency is set close to the entered stop frequency, and the start frequency
is set equal to stop/n.
