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).
Procedure This procedure asks you to close every switch in your standard system, and
look for an appropriate signal with the measurement system.
1. Press: [Select Instr] {85330A} .
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.
6. Perform a measurement with your system. The measurement system
should be able to measure any signal present on the selected channel.
7. Repeat these steps for each channel on each switch port.
