Chapter 1 Performance Tests
Operational Verification
Operational Verification
Operational Verification is an abbreviated series of tests that you can
perform (instead of performing the Complete Performance Tests) to
provide a high degree of confidence that the instrument is operating
properly. Operational Verification is useful for incoming inspection,
routine maintenance, and after instrument repair.
If you are not familiar with operating the Counter, you should review
Chapter 1, "Getting Started," in the Agilent 53150A/151A/152A
Operating Guide. However, the procedures in this chapter are written so
that little experience is necessary. These procedures should be followed in
the order in which they appear.
Power-On Self Tests
This test is appropriate for the Agilent 53150A, 53151A, and 53152A
Counters.
Inspect the Counter for damage.
Make sure no cables are connected to the Counter's inputs.
Connect the power cord to the Counter and the power source.
Since the Counter's power supply automatically senses the line voltage,
there is no AC input-voltage setting.
Turn on the Main ~ Power switch on the Counter's rear panel.
It is normal for the fan in the Counter to run when the Counter is in
Standby mode. Power is supplied to the timebase whenever the
Main ~ Power switch is on to maintain long-term measurement reliability,
and the fan helps to maintain the timebase's temperature stability.
Press and release the Power button on the front panel.
