Signal not found
Indicates the PEAK ZOOM routine did not find a valid signal. (U)
Signals do not fit expected
%
AM pattern
Indicates that the % AM routine cannot perform the percent AM measurement because the
on-screen signals do not have the characteristics of a carrier with two sidebands. (U)
Signals do not flt expected TO1 pattern
Indicates that the TO1 routine cannot perform the third-order intermodulation measurement
because the on-screen signals do not have the characteristics of two signals and two
distortion products. (U)
SMPLR UNLCK
Indicates that the sampling oscillator circuitry is not functioning properly. If this message
appears, check that the external frequency reference is correctly connected to the EXT REF
INPUT. (U) and (H)

Indicates the step gain has failed. (H)
Stop at marker not available with negative detection
Indicates that the marker counter cannot be used when negative peak detection is selected.

EMPTY DLP MEM
Indicates that the user-defined items (user-defined functions, user-defined variables,
user-defined traces, user-defined softkeys) and any personalities (for example, the HP 85716A
CATV System Monitor Personality) in the spectrum analyzer’s memory have been deleted.
If this message appears, use ERASE DLP
NEM
to clear spectrum analyzer memory. If the
message is still displayed, it may indicate a hardware failure. See the spectrum analyzer’s
Service Guide for more information. (U)
TABLE FULL
Indicates the upper or lower table of limit lines contains the maximum number of entries
allowed. Additional entries to the table are ignored. (U)
TG SIGNAL NOT FOUND
Indicates the tracking generator output signal cannot be found. Check that the tracking
generator output (RF OUT 500 or RF OUT
75Q)
is connected to the spectrum analyzer input
connector with an appropriate cable. (U)
TG UNLVL
This message can indicate the following: that the source power is set higher or lower than
the spectrum analyzer can provide, that the frequency span extends beyond the specified
frequency range of the tracking generator, or that the calibration data for the tracking
generator is incorrect. See “Stimulus-Response Measurements” in Chapter 4 of the HP 8590

Too
many signal with valid N dB points
Indicates the N
dB
PTS function has located two or more signals that have amplitudes within
the specified
dB
from the signal peak. If this happens, you should decrease the span of the
spectrum analyzer so that only the signal that you want to measure is displayed. (U)
