4·34. Test Equipment Substitutions
The included Semi-Automatic Performance Test software is designed to be used with the
calculator, printer and frequency synthesizers listed under Recommended Test Equipment,
Table 4-6. Other HP-IB compatible controllers and instruments may be used for the tests;
however, the user must write his own software to be compatible with his particular equip­
ment. Substitute test equipment must meet the critical specifications listed in Table 4-1 .
HP-IB is Hewlett-Packard's implementation of IEEE std
488-1975,
strumentation ".
4·3 5. Manual Tests
Before pro ceding with the calculator controlled portion of the semi-automatic performance
tests, two manual tests must be performed. The first of these tests is for frequency accuracy,
and the second test checks the 1 M ohm input impedance and capacitance.
4·36. Frequency Accuracy
This test verifies the frequency accuracy of the 3585A by using an external counter to check
the internal frequency reference. It is important that the frequency counter used to do this
test has a reference which is more accurate than that of the 3585A.
Specification: Counter Accuracy, ± O.3Hz ± lxlO- 7 /month
