Using The Instrument
Overview
This chapter contains information about how to operate the Model
3152. Unlike bench-type instruments, the Model 3152 must be
programmed to turn on functions, change parameters and configure
various operating modes. The instrument can be programmed using
a set of SCPI commands. A list of SCPI commands that control the
Model 3152 is given in Table 4-1. The following paragraphs
describe the various modes of operation and give examples on how
to program the Model 3152.
Output
Termination
During use, output connectors must be properly terminated to
minimize signal reflection or power loss due to an impedance
mismatch. Proper termination is also required for an accurate
amplitude level at the main output connector. Use 50
S
cables and
terminate the main and SYNC cables with terminating resistors.
Always place the 50
S
termination at the far end of the cables.
Input/Output
Protection
The Model 3152 provides protection for internal circuitry connected
to input and output connectors. Refer to the specifications in
Appendix A to determine the level of protection associated with
each input or output connector.
Power On/Reset
Defaults
At Power On or as a result of a software reset, the Model 3152
defaults to the conditions shown in Table 3-1. A complete list of all
parameters and their default values is given in Chapter 4.
Use the following command to place the instrument in its default
state:
RESet;
Using the IEEE-STD-488.2 common command *RST will have the
same result.
