select input
rst module in the signal path (another example is the
NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN
IN 1 LW 70810A softkey). The modules
are displayed in a sequence that is dependent on the HP-MSIB address and module model
designation of each module . The order of input ports is sorted by the module address , column
address before row address , in ASCII order . If there are two input ports at one HP-MSIB
module address , the module model number is also used to determine the order of input ports .
F or example , an HP 70810B lightwave section sets the system input-port order so that its
OPTICAL INPUT is input 1 and its RF INPUT is input 2.
Refer to HP 70000 Modular Spectrum Analyzer Installation and V erication Manual for
information about the correct HP-MSIB module addresses to use for proper spectrum analyzer
and lightwave signal analyzer system conguration.
The input-port number is required during certain programming situations . Checking the
input-port number on the softkey label is a simple way to determine the input-port number .
Note
Changes in hardware conguration or rmware revision can aect the
displayed numbering of the system inputs . When programming the commands
INPUT , INPUTMOD , and MOD ADD can be used to verify the proper input
selection.
