Indicates the specified trace could not be saved because the trace name is not allowed. ‘lb
avoid this problem, use an underscore as the second character in the trace name, or avoid
beginning the trace name with the following pairs of letters: LB, OA, OL, TA, TB, TR, MA,
MF, TS, OT, and DR. (U)
INVALID VALUE PARAMETER:

avoid this problem, use an underscore as
the second character in the variable label, or avoid beginning the variable label with the
following pairs of letters: LB, OA, OL, TA, TB, TR, MA, MF, TS, OT, and DR. (U)

The specified window is invalid. See the description for the TWNDOW programming
command. (U)
LOST SIGNAL
For the HP
8592L,
HP 85933, or HP 85963, this message indicates that the cable from the
100 MHz COMB OUT connector to the spectrum analyzer input is defective or has become
disconnected during the CAL YTF routine. For the HP 85953, this message indicates that the
cable from the CAL OUT connector is defective or has been disconnected during the CAL
YTF routine. Be sure to use a short, low-loss cable to connect the signal to the spectrum
analyzer input when performing the CAL YTF routine. (U)
LO UNLVL
Indicates that the spectrum analyzer’s local oscillator distribution amplifier is not functioning
properly. (H)
Marker Count Reduce SPAN
Indicates the resolution bandwidth to span ratio is too small to use the marker count
function. Check the span and resolution bandwidth settings. (U)
Marker Count Widen RES BW
Indicates that the current resolution bandwidth setting is too narrow to use with the marker
counter function. The marker counter function can be in narrow resolution bandwidths
(bandwidths that are less than 1
kHz)
with the following procedure:
1. Place the marker on the desired signal.
2. Increase the resolution bandwidth to 1
kHz
and verify the marker is on the signal peak.
3. If the marker in on the signal peak, the marker count function can be used in either the
1
kHz
resolution bandwidth or the original narrow resolution bandwidth setting. If the
marker is not on the signal peak, it should be moved to the signal peak and the marker
counter function should not be used with a resolution bandwidth setting of less than
1
kHz.

No card found
Indicates that the memory card is not inserted. (U)
No points defined
Indicates the specified limit line or amplitude correction function cannot be performed
because no limit line segments or amplitude correction factors have been defined. (U)
