Getting Started
The HP 83487A Optical/Electrical Plug-In Module
Front panel of the plug-in module
The plug-in module takes up two of the four mainframe slots. The optical
channel provides calibrated measurement of optical waveforms in power
units. The electrical channel provides calibrated measurement of electrical
signals in volts. Bandwidths are selectable on both channels to optimize sensi-
tivity and bandwidth.
The front panel of the plug-in module has two channel inputs and an external
trigger input. The front panel also has a Probe Power connector for HP 54700-
series probes, an Aux Power connector for general purpose use, and a key for
each channel that displays the softkey menu. The softkey menu allows you to
access the channel setup features of the plug-in module.
The front-power Probe Power connector allows automatic channel scaling and
probe calibration with HP 54700 series probes. The front-panel Aux Power con-
nector provides only power to HP 54700 series probes for use as a trigger
input. Probe calibration and scaling are not required for a trigger input.
