NOTE
If you wish to use the HP 83487A optical plug-in module in an HP 54750A digitizing
oscilloscope, a firmware upgrade must first be installed. Order the HP 83480K communi-
cations firmware kit and follow the installation instructions.
The purpose of the plug-in module is to provide measurement channels,
including sampling, for the mainframe. The plug-in module scales the input
signal, sets the bandwidth of the system, and allows the offset to be adjusted
so the signal can be viewed. The output of the plug-in module is an analog sig-
nal that is applied to the ADCs on the acquisition boards inside the mainframe.
The plug-in module also provides a trigger signal input to the time base/trigger
board inside the mainframe.
For HP-IB programming information, refer to the HP 83480A, 54750A Pro-
grammer's Guide supplied with the mainframe.
