HP-MSIB Troubleshooting Utility
The HP-MSIB Troubleshooting Utility is built into the display element of the analyzer.This
utility is not automatic, and it interferes with normal system operation. Refer to the display's
Installation and Verication Manual for additional information.

systems
.
There
are separate system diagnostics programs designed for use
with
specic

.
When
testing
a
lightwave
signal
analyzer and using System Diagnostics software versions dated
C.01.00,
and
earlier
,
disconnect
the cable between the RF OUTPUT of the lightwave section
and
the RF INPUT of the RF section. Connect the CALIBRATOR output directly to the RF
INPUT
of the RF section and perform the diagnostics test. Performing the test in this manner
veries
the performance of the spectrum analyzer. Refer to the \Troubleshooting a Lightwave
Signal Analyzer" section in this chapter for troubleshooting information about the lightwave
section.

The
System
Diagnostic program is loaded into the HP 70900B local oscillator source RAM at the
factory
for most precongured systems.
For more detailed information on the software, refer to \System Diagnostics" later in this
section. Refer to the
HP 70000 Modular Spectrum Analyzer Installation and Verication
Manual
for listings of which versions of System Diagnostics software, module hardware,and
rmware models are compatible.
Operation Verication
Operation Verication is an external test program that runs on HP 9000 Series 200/300
controller and requires external test equipment.
The primary purpose of Operation Verication is to verify that the spectrum analyzer meets
its major specications; however, it also contains several testing modes that are useful for
troubleshooting. For example, Operation Verication allows repeated testing of individual
specications. Repeated testing can be useful for troubleshooting intermittent problems
.
Since Operation V
erication tests the spectrum analyzer against specications
, the test may nd
failures that are not found by System Diagnostics
.
