Model 8642A/B Performance Tests
PERFORMANCE TESTS
4 - 1 . INTRODUCTION
The procedures in this section test the instrument's electrical performance using the
specifications from Table 1 - 1 as the performance standards. All tests can be performed without
access to the interior of the instrument. Data points are given both for the 8642A and the
8642B; when testing an 8642A delete the data points that apply only to the 8642B. In general,
these are the specifications for RF frequencies greater than 1057.5 MHz unless otherwise noted.
NOTES
/ / the performance tests are to be valid the following
conditions must be met:
a. The HP 8642 must have a 30 minute warmup.
b. The mains (line) voltage must be within +5-10%
of 100, 110, 220 or 240 volts rms AC at 47.5 -
440 Hz-
c. The ambient temperature must be 0 to +55
degrees C.
d. Before aging rate tests are performed, the HP
8642 must have a 8 day warmup if it has been
disconnected from the Mains power for more
than 24 hours, or if the HP 8642 has been
disconnected from the Mains power for less
than 24 hours it must have a 24 hour warmup.
4-2. RECOMMENDED TEST EQUIPMENT
Equipment required for the performance tests is listed in the Recommended Test Equipment
table in Section I. Any equipment that satisfies the critical specifications given in the table may
be substituted for the recommended model(s).
4 - 3 . TEST RECORD
Results of the performance tests may be tabulated in the Test Record at the end of the
procedures. The Test Record lists all of the tested specifications and their acceptable limits. The
results recorded at incoming inspection can be used for comparison in periodic maintenance and
troubleshooting and after repairs or adjustments.
