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.
