HP 8590 E-Series User Manual

Error Messages
The spectrum analyzer can generate various messages that appear on its screen during
operation to indicate a problem.
There are three types of messages: hardware error messages (H), user-created error messages
(U), and informational messages (M).
n Hardware error messages indicate the spectrum analyzer hardware is probably broken.
w User-created error messages appear when the spectrum analyzer is used incorrectly. They are
usually generated during remote operation (entering programming commands using either a
controller or the external keyboard).
n Informational messages provide information indicating the spectrum analyzer progress within
a specific procedure.
The messages are listed in alphabetical order on the following pages; each message is defined,
and its type is indicated by an (H), (U), or (M).
4 LOCK OFF
Indicates slow YTO tuning. This message may appear if the spectrum analyzer is using
default correction factors. If this message appears constantly, perform the CAL FREQ routine
to try to eliminate this message. 4 LOCK OFF appears briefly during the CAL FREQ routine,
during instrument preset, or when the frequency value is changed; this is normal and does
not indicate a problem. (U) and (H)
ADC-2V FAIL
ADC-GND FAIL
ADC-TIME FAIL
Cal harmonic > = 5.7 GIIz NOT found
Indicates that the CAL YTF routine for an HP 85953 cannot find a harmonic of the 300 MHz
calibration signal. If this happens, ensure that the CAL OUT connector is connected to the
spectrum analyzer input, perform the CAL FREQ & AMPTD routine, and then perform the
CAL YTF routine again. (U) and (H)
CAL:- - -
During the self-calibration routine, messages may appear on the display to indicate how the
calibration routines are progressing. For example, sweep, freq, span, MC delay, FM coil,
and atten can appear on the spectrum analyzer display. 4 LOCK OFF appears briefly during
the CAL FREQ self-calibration routine; this is normal and does not indicate a problem. (M)
CAL: DONE: Press CAL STORE to save
Indicates that the self-calibration routine is finished and that you should press CAL STORE .
(Ml
CAL: cannot execute CALAMP enter: 0 dB PREAMP GAIN
The preamplifier gain should be set to 0 dB before the CAL AMPTD routine is performed.
The preamplifier gain is set by using EXTERNAL PREAMPG . This message also sets SRQ 110.
