Aooendix B: Pcrformarxc Verification
Performance Test Overview
The proccdurcs arc in three groupings: Signal Acquisition System Checks, ?ime
Bass System Checks, and Triggering System Checks. They check ah the
characteristics that appear in boldface type und&Warranted Characteristics on
page A-l.
Prerequisites
The tests in this subsection comprise an extensive, valid confrrnation of
performance and functionality when the following requirements are met:
The cabinet must bc installed.
You must have performed and passed the procedures under Self Tests, on
page l-5 and those under Functional Tests, on page 1-7.
The digitizing oscilloscope must have been operating for a warm-up period
of at least 20 minutes, and must bc operating at an ambient tcrnperature
between -10” C and +5S” C.
Signal Acquisition System Checks
These procedures check signal acquisition system characteristics that are listed as
checked under Wurranted Characteris6ics in the Specifications
sccl:ion.

Measurement Accuracy
n
!
WARNING. Pe~fom~ance of this procedure requires input voltages tip to 98 VUC.
Contact with live circuits could cause injury or death. Be sure to set the DC
calibration generator to 0 vah bcforc connecting, disconnecting, and/or moving
the test hookua durinz the oerformance ofchis orocedure.
Equipment Required: One dual-banana connector (Item 3). one DC calibration
generator (Item 6), and one precision coaxial cable (Item 2).
Time Required: Approximately 35 minutes.
Prerequisites: The oscilloscope must meet the prerequisites listed on
page B-5.
Procedure:
1. Set the output of a DC calibration generator to 0 volts.
