Powering Up the Distribution Amplifier

 

Overview of the Power-Up Procedure (What to

 

Expect)

 

When you power up the 58502A Distribution Amplifier for the first

 

time, you should expect it to run through the following sequence:

 

• front-panel Alarm indicator momentarily flashes, indicating the

 

unit is going through self-test, and

 

• enters steady-state operation, acting as a twelve-channel

 

distribution amplifier.

 

To Power Up the Distribution Amplifier

 

The 58502A may be operated without a terminal or computer. The

NOTE

 

computer is needed for you to remotely monitor the status of the

 

58502A and to change setup parameters.

 

 

1As shown in Figure 1-3 (note that the terminal or computer is optional), connect the 58502A’s outputs as required for your application, and provide at least one input at either the input A or B rear-panel input connector.

NOTE

Without 50Ω termination of the outputs, the front-panel OUTPUT

 

STATUS indicators may not operate properly because the amplitude of

 

the output signals may not be within specifications.

 

See the section “Features and Functions” in Chapter 3, “Features and

 

 

Functions,” for information on connection and operation for your

 

chosen application.

2If you are using the Distribution Amplifier with a terminal, personal computer (PC) see the section “Connecting a Terminal or Computer to the 58502A” starting on page 1-5.

3Apply the proper power source to the rear-panel AC input jack of the Distribution Amplifier. (See the subsection “To Connect AC Power” on page 1-5.)

If an input signal is connected to either input A or B, the 58502A should now be distributing the input signal to all 12 output ports.
