If the System Fails the Verification Test
1. Disconnect and clean the device that failed the verification test.
2. Reconnect the device making sure that all connections are torqued to the
proper specifications.
3. Measure the device again.
4. If the analyzer still fails the test, check the measurement calibration by
viewing the error terms as described in “Accessing Error Terms” on
page 8-6.
5. Refer to Figure 3-11 for additional troubleshooting steps.
For printed output, it is assumed that the printer has been tested and the
Windows driver is installed for the printer that is being used. The system
verification test prints to the printer that has been designated as the
default printer. (On the Windows Desktop display, click on My Computer,
Control Panel, and then Printers to verify the printer setup.)
Inspect all connections. Do not remove the cable from the analyzer test
port. This will invalidate the calibration that you performed earlier
