Output
Termination
During use, output connectors must be properly terminated to
minimize signal reflection or power loss due to 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 3156B 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 instrument defaults
to some factory pre-selected conditions. A complete list of all
parameters, their default values, as well as their maximum and
minimum values is given in Chapter 4.
Use the following function call to place the instrument in its default
state:
