Quick Start: Learning How to Make Measurements

If You Encounter a Problem

CAUTION If the error message:

CAUTION: OVERLOAD ON INPUT X, POWER REDUCED

appears on the analyzer display, too much source power is being applied at the input. In such a case, the input power will need to be reduced before the source power will remain on.

❏If phase-lock error messages appear on the analyzer display, check that the front panel jumper is secure on the R CHANNEL connectors. If the jumper is secure and the error messages still appear, contact your nearest Agilent Technologies ofﬁce for service. A list of Agilent Technologies sales and service ofﬁces is provided in Table 2-1 on page 2-26.
