[SENSe:]CURRent[:DC]:APERture {<seconds> | MIN | MAX | DEF} [, (@<ch_list>)]

[SENSe:]CURRent[:DC]:APERture? [{(@<ch_list>) | MIN | MAX | DEF}]

Enables the aperture mode and sets the integration time in seconds (called aperture time) for DC current meas-

urements.

Parameter Typical return

200 μs to 1 s (2 μs resolution). Default: 100 ms +1.00000000E- 01

Enable aperture time mode, set the aperture time to 300 ms:

CURR:APER:ENAB ON

CURR:DC:APER 300E-03

–

You can specify MIN (smallest value accepted) or MAX (largest value accepted) instead of <seconds>.

– Only the integral number of power line cycles (1, 2, 10, 20, 100, or 200 PLCs) provide normal mode (line fre-

quency noise) rejection.

– The CONFigure:CURRent[:DC], MEASure:CURRent[:DC], [SENSe:]CURRent[:DC]:NPLCycles, [SENSe:]CURRent

[:DC]:RESolution commands automatically disable the aperture time mode, and select an integration time in

number of power line cycles.

– This parameter is set to its default value after a Factory Reset (*RST command).

[SENSe:]CURRent[:DC]:APERture:ENABle {OFF | ON} [, (@<ch_list>)]

[SENSe:]CURRent[:DC]:APERture:ENABle? [(@<ch_list>)]

Enables the setting of integration time in seconds (called aperture time) for DC current measurements. If aperture

time mode is disabled (default), the integration time is set in PLC (power-line cycles).

Parameter Typical return

{OFF | ON}. Default: OFF 0 (OFF) or 1 (ON)
