PERFORMANCE TESTS
4-25. The following procedures test the electrical performance of the
HP
5334B Universal Counter using the
specifications
in
Table
1-1
as the performance standards. The tests included here are much more specific and
rigorous than the operational verification procedures. Use these procedures to ensure that the instrument in
question is operating at its highest level at
incoming
QA,
the annual calibration cycle check, or following any of
the adjustment procedures.
4-26.
The procedures were designed to be performed sequentially in order to fully test the
HP
5334B.
NOTE
If the performance tests are to be considered valid, the the following condi-
tions must be met:
a.
The Universal Counter must have
a
30-minute warmup.
b.
The reference oscillator must be set to a frequency standard. Perform
the Reference Oscillator Frequency Adjustment before beginning these
tests. This is adjustment
5-15
in Section
V,
ADJUSTMENTS, of this
manual.
NOTE
The
+
resolution limits specified in the following procedures assume that
the test equipment being used is calibrated and operating at its perfor-
mance limits. When this is not the case, problems can occur. For example,
noise on an input signal to the Counter will result in the display of what
seems to be an inaccurate measurement. This condition must be con-
sidered when observed measurements do not agree with the performance
test limits
4-27. Preliminary Procedure
CAUTION
Before the Universal Counter is switched on, it must be set to the
same line voltage as the power source or damage to the instrument
may result. For details, see Power Requirements, Line Voltage Selec-
tion, Power Cable, and associated warnings and cautions in Section
II
of the Operating and Programming Manual.
