There are four types of signal distribution that can be used with the

58502A:

• Distribution of one input (A or B)

• Distribution of two inputs (A and B)

• Distribution of input A with internal backup oscillator (OCXO)

• Distribution of the internal backup oscillator (OCXO) only

Each of the above require a different set of commands to be used with

this instrument. See the subsection “Setup Commands for the

Different Distribution Applications” starting on page 1-12.

There are tasks that are common to all distribution applications. These

are:

• Checking the Output Channels Status

• Changing the RS-232 Serial Port Characteristics

The example commands to perform these tasks are described in the

subsection “Commands That Are Common to All Distribution

Applications” starting on page 1-14.
