Using The Instrument
Overview
This chapter contains information about how to operate the Model
3151/3151A. Unlike bench-type instruments, the Model 3151/3151A
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 affect the Model 3151/3151A is given in Table 4-1.
The following paragraphs describe the various modes of operation
and give examples on how to program the Model 3151/3151A.
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
Ω
cables and
terminate the main and SYNC cables with terminating resistors.
Always place the 50
Ω
termination at the far end of the cables.
Input/Output
Protection
The Model 3151/3151A 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
3151/3151A 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
.
