Performance Verification
4-8
AWG710 Service Manual
The tests in this section produce an extensive, valid confirmation of performance
and functionality when the following requirements are met:
H The cabinet must be installed on the instrument.
H You must have performed and passed the procedures under Self Tests, found
on page 4–3.
H The waveform generator must have been recently adjusted at an ambient
temperature between +20_ C and +30_ C, must have been operating for a
warm-up period of at least 20 minutes, and must be operating at an ambient
temperature between +10_ C and +40_ C.
Refer to Conventions on page 4–2 for more information.
These procedures use external, traceable signal sources to directly check
warranted characteristics. Table 4–2 lists the equipment required to complete the
performance tests.
