Troubleshooting

An understanding of how the 85330A system operates is required before undertaking the troubleshooting of this system. Please read “Theory of Operation” on page 9-2.

This system may be broken down into four parts: multiple channel controller (mainframe), switch control unit, RF switch, and cables. In order to determine which part of the system is not working correctly, a performance veriﬁcation may be run. For more information, see Chapter 2, “Performance Veriﬁcation.”

NOTE

Turn ON Self Check

The following screen should appear when you turn the 85330A ON.

SYSTEM 85330A IBASIC (see note below)

IBASIC is present only if the IBASIC option is installed.

If you see this display, go on to the next troubleshooting section. If you do not see this display, load the 85330A downloadable driver ﬁles as explained in Chapter 1, “Installation.”

Multiple Channel Controller

Run the test “Verifying the Multiple Channel Controller” on page 2-6.

VXI Mainframe

For troubleshooting information on the E1301B VXI mainframe, see the Service chapter in the Agilent E1301B Service Manual. There are a couple of VXI mainframe self tests that can be used, as well as the command *TST?.

85330-60002 Card

The multiple channel controller tests, shown above, will check this plug-in card.

To check the SWITCH PORT1 and SWITCH PORT2 output connector, refer to Table 9-3 on page 9-11for each control line function. Use a digital scope or a logic analyzer to monitor these lines.
