Driver Function Reference
hpe5250a_self_test
the R, L, and C value, measure R, L, and C of the cable using the 4284A, and divide
them by cable length (in m). Compensation data must be the value for 1 m length.
Do not change the data format in the file.
hpe5250a_self_test
This function causes the instrument to perform a self-test and returns the result of
that self-test. This is used to verify that an instrument is operating properly. A failure
may indicate a potential hardware problem.
Syntax ViStatus _VI_FUNC hpe5250a_self_test(ViSession vi, ViPInt16 test_result,
ViChar_VI_FAR test_message[ ]);
Parameters vi Instrument handle returned from hpe5250a_init( ).
test_result Numeric result from self-test operation. 0: No error.
test_message[ ] Self-test status message. This is limited to 256 characters.
hpe5250a_testClear
This function clears the test result for the specified relay card or the front panel or
the controller.
Syntax ViStatus _VI_FUNC hpe5250a_testClear(ViSession vi, ViInt16 framecard_clear);
Parameters vi Instrument handle returned from hpe5250a_init( ).
framecard_clear Test result to be cleared. 0 (test result of all test), 1 (card 1 relay
test result), 2 (card 2 relay test result), 3 (card 3 relay test
result), 4 (card 4 relay test result), 5 (relay test result of all
card), 6 (front panel test result), or 7 (controller test result).
