2 Equipment Required; 4-3'. Calibration Cycle - HP 41951A Operation Note

SECTION 4
VERIFICATION TEST
4~1. SNTRODUCTION
This section contains the basic operational checkout procedures for the HP 41951 A. All
tests can be performed without access to the interior of the 41951 A, The verification test is
typically used for incoming inspection of the 41951 A, and to verify that the Impedance Test
Adapter is in good order after it has been repaired.
4-2. EQUIPMENT REQUIRED
Table 4-1 lists the equipment required to perform the verification test. Equipment that meets
or exceeds the critical specifications listed in the table may be used as a substitute for the
recommended models. The equipment used for verification testing must be calibrated.

4-3. CALIBRATION CYCLE
The 41951A requires periodic performance verification. The 41951A (Impedance Test
Adapter) should be checked out using the verification test at least once a year or more
depending on the frequency of use. Preventive maintenance should be performed at least
twice a year to keep down-time to a minimum, and to insure optimum operation,
