34410A/11A/L4411A Service Guide 71
Calibration Procedures 3
AC Current Verification Test
Configuration: AC Current (CONFigure:CURRent:AC)
LF 3 HZ:SLOW ([SENSe:]CURRent:AC:BANDwidth 3)
1 Make sure you have read “Test Considerations” on page 63.
2 Connect the calibrator to the input terminals.
a For the 34410A/11A use the front panel input terminals and select
the Front input terminals with the Front/Rear switch.
3 Set the AC Current function and the 3 Hz input filter. With the slow
filter selected, each measurement takes 1.7 seconds to complete.
4 Select each range in the order shown below. Provide the input current
and frequency indicated. Compare measurement results to the
appropriate test limits shown in the table. (Be certain to allow for
appropriate source settling.)
