System Diagnostics Requirements: Version C.03.00
Requirements for running System Diagnostics are explained in this section. Also provided is
information on how to avoid problems.
System Diagnostics can be destroyed if the program is in the local oscillator RAM and then the
ERASE command is executed or the
NNNNNNNNNNNNNNNNNNNNNNNNNNNNN
ERASE ALL
softkey is pressed. It can also be destroyed by
the user if each user-dened function (FUNCDEF) and variable denition (VARDEF) has been
individually unprotected and the DISPOSE ALL command executed.
System Diagnostics will take up approximately 12 K of local oscillator RAM to run. To
determine how much user RAM is available after the system diagnostics program is loaded,
display a catalog of internal memory by pressing

HP-MSIB Addressing Order
In addition to meeting the normal addressing requirements, the HP-MSIB addresses of the
spectrum analyzer must meet these additional requirements:
The local oscillator must have a row address of 0.
If the HP 70900B local oscillator source is a sub-master, not addressed in row zero, its master
must
be
removed
and
the
HP
70900B
local oscillator source readdressed to row zero before
system
diagnostics
will
run.
The
local
oscillator
to
be
tested
must have a lower column address than other local oscillators
at
row
address
0.
Error
messages
are
generated
if
the
above requirements are not met.

Calibrator Signal
To run System Diagnostics for an HP 71100C modular spectrum analyzer/HP 71200C modular
spectrum analyzer/HP 71210C microwave spectrum analyzer, the CALIBRATOR output of the
HP 70900B local oscillator source must be connected to the RF INPUT of the RF Section. This
connection is not necessary for any system with an HP 70907A/B external mixer interface
module used as the RF Section to be tested. The HP 70907A/B external mixer interface module
provides its own internal calibrator.To run System Diagnostics for the HP 71400C lightwave
signal analyzer and HP 71401C lightwave signal analyzer, disconnect the cable between the
RF OUTPUT of the lightwave section and the RF INPUT of the RF section. Connect the
CALIBRATOR signal directly to the RF INPUT of the RF section.
The System Diagnostics program cannot be run with the lightwave section in the signal path.
Rerouting the signal path allows the performance of the spectrum analyzer portion of the
lightwave signal analyzer to be tested separately
. The HP 71400C lightwave signal analyzer
combines an HP 70810B lightwave section with an HP 71210C microwave spectrum analyzer
modular spectrum analyzer. The HP 71401C lightwave signal analyzer combines an HP 70810B
lightwave section with an HP 71100C modular spectrum analyzer.
Making Backup Copies of System Diagnostics
If there is access to an HP 9000 Series 200/300 controller for running System Diagnostics,the
System Diagnostics disk shipped with this manual can serve as the backup.For instructions,
refer to \Running the System Diagnostics Utilities".
If access to an HP 9000 Series 200/300 controller is not possible,usetheUSTATE command
to make a backup copy for your computer. Refer to
HP 70000 Modular Spectrum Analyzer
