TLA721 Benchtop & TLA7XM Expansion Mainframe Service Manual
4- 1
Performance Verification Procedures
This chapter contains procedures for functional verification, certification, and
performance verification procedures for the TLA721 Benchtop Mainframe and
TLA7XM Expansion Mainframe. Generally, you should perform these proce-
dures once per year or following repairs that affect certification.
Summary Verification
Functional verification procedures verify the basic functionality of the instru-
ment inputs, outputs, and basic instrument actions. These procedures include
power-on diagnostics, extended diagnostics, and manual check procedures.
These procedures can be used for incoming inspection purposes.
Certification procedures certify the accuracy of an instrument and provide a
traceability path to national standards. Certification data is recorded on calibra-
tion data reports provided with this manual. The calibration data reports are
intended to be copied and used for calibration/certification procedures.
After completing the performance verification procedures or the certification
procedures, you can fill out a calibration data report to keep on file with your
instrument.
Performance verification procedures confirm that a product meets or exceeds the
performance requirements for the published specifications documented in the
Specifications chapter of this manual. Refer to Figure 4--1 on page 4--2 for a
graphic overview of the procedures.
Test Equipment
These procedures use external, traceable signal sources to directly test character-
istics that are designated as checked (
n
) in the Specifications chapter of this
manual. Table 4--1 on page 4--3 shows the required equipment list. Always
warm up the equipment for 30 minutes before beginning the procedures.
