NOTE
In the interest of PRESERVING its usability the information in
this chapter has been retained in its original form without
changes. No attempt has been made to update the equipment,

necessary for the user of this manual to consider the

This chapter provides procedures to test the electrical performance of the
5071A Primary Frequency Standard, using the specifications listed in
Chapter 6, “Specifications.” Three types of tests are provided:
•
Operational Verification
•
Complete Performance Tests
•
RS-232 Verification
Operational Verification
The Operational Verification test is an abbreviated series of checks that may
be performed to give a high degree of confidence that the instrument is
operating properly without performing the complete Performance Tests. An
operational verification is useful for incoming inspection, routine
maintenance, and after instrument repair.
Complete Performance Tests
The complete Performance Tests verify the specifications listed in Chapter 6
of this manual. All tests can be performed without access to the inside of the
instrument.
RS-232 Verification
The RS-232 Serial Port verification checks the serial port for successful data
communication with a terminal or PC.
