Installation
The SD-42/SD-46 Optical-to-Electrical Converter Head fits into the front panel
of an 11800 Series Digital Sampling Oscilloscope or a CSA 803 Communica-
tions Signal Analyzer. See Figure 1–1.
The SD-42/SD-46 Optical-to-Electrical Converter Head converts optical signals
to electrical signals to be sampled. At least one sampling head must be installed
in the oscilloscope for the instrument to sample signals.
For the converted output signal from the SD-42/SD-46 to be sampled, the output
of the SD-42/SD-46 must be connected to the input of an SD-24 or SD-26
Sampling Head (the SD-42 can also be connected to an SD-22). To accomplish
this using the U-link provided with the SD-42/SD-46, the SD-24 or SD-26 must
be in the plug-in slot immediately to the right of the slot occupied by the SD-46.
The output of the SD-42/SD-46 is then connected to the lower input of the
SD-24 or SD-26.
To install a plug-in, first switch off the oscilloscope. Then place the plug-in in a
compartment and slowly push it in with firm pressure. Once the plug-in is
seated, turn the screw shaft on the plug-in to tighten the plug-in in place.
