Operator’s Check

Purpose

This operator’s check verifies that the Agilent 85330A can close switches, showing that the 85330A, switch control units, and switches are working.

You can perform this check daily, or as desired. This is not a performance verification procedure (refer to

Chapter 2, “Performance Verification” for

more information).

This procedure asks you to close every switch in your standard system, and look for an appropriate signal with the measurement system.

2. If the {CLOSE} softkey does not appear, press [Prev Menu] until it does.

3. Press: {CLOSE} a.

If the switch you want to close is connected to SWITCH PORT 1, press {PORT_1} .

b.

If the switch you want to close is connected to SWITCH PORT 2, press {PORT_2} .

4. Enter the switch address using the numeric keypad. In a standard system, simply enter the channel number (1, 2, 3, or 4), and press

[Return] . If you have a custom system, refer to

Chapter 5, “Manual

Operation” for instructions.

5. Look at the channel LEDs on the front of the switch control unit. The light for the selected channel should be ON. This shows that the SCU is responding properly.
