Performance Tests
These procedures confirm that the oscilloscope functions within warranted
limits.The procedures are in three groupings: Signal Acquisition System Checks,
Time Base System Checks, and Trigger System Checks. They check all the
characteristics that appear in boldface type under Warranted Characteristics on
page 1–1.
Prerequisites
The tests in this subsection comprise an extensive, valid confirmation of
performance and functionality when the following requirements are met:
H The cabinet must be installed.
H You must have performed and passed the procedures under Self Test, on
page 4–5, and those under Functional Test, on page 4–7.
H The oscilloscope 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 +55_ C.
Signal Acquisition System Checks
These procedures check signal acquisition system characteristics that are listed as
checked under Warranted Characteristics in the Specifications section.
WARNING. Performance of this procedure requires input voltages up to 98 VDC.
Contact with live circuits could cause injury or death. Be sure to set the DC
calibration generator to 0 volts before connecting, disconnecting, or moving the
test hookup during the performance of this procedure.
