Most equipment is subject to a small amount of drift when it is first
turned on. To ensure accuracy, turn on the power to the Model 2074
and allow it to warm-up for at least 30 minutes before beginning the
performance test procedure.
To avoid confusion as to which initial setting is to be used for each
test, it is required that the instrument be reset to factory default values
prior to each test. To reset the Model 2074 to factory defaults, use the
Factory Rest option in the Utility menu.
Recommended test equipment for troubleshooting, calibration and
performance checking is listed in Table 6-1 below. Test instruments
other than those listed may be used only if their specifications equal or
exceed the required characteristics.

Use the following procedures to check the Model 2074 against the
specifications. A complete set of specifications is listed in Appendix A.
The following paragraphs show how to set up the instrument for the
test, what the specifications for the tested function are, and what
acceptable limits for the test are. If the instrument fails to perform
within the specified limits, the instrument must be calibrated or tested
to find the source of the problem.
Frequency accuracy checks tests the accuracy of the internal
oscillators. All channels share the same output frequency and the
same reference oscillators and therefore, the accuracy is tested on
channel 1 only.
