VOLTage:DC:APERture {<time>MINMAX}[,(@<ch_list>)] RESistance:APERture {<time>MINMAX}[,(@<ch_list>)] FRESistance:APERture {<time>MINMAX}[,(@<ch_list>)] CURRent:DC:APERture {<time>MINMAX}[,(@<ch_list>)]

Select the aperture time for the function selected on the specified channels. MIN selects the smallest value accepted for this parameter, which gives the most resolution. MAX selects the largest value accepted for this parameter, which gives the least resolution.

For more information on aperture time, refer to “Custom A/D Integration Time” in chapter 4 starting on page 103.

FREQuency:APERture {0.010.11MINMAX}[,(@<ch_list>)] PERiod:APERture {0.010.11MINMAX}[,(@<ch_list>)]

Select the aperture time (or gate time) for frequency or period measurements on the specified channels. Specify 10 ms (41⁄2 digits),

100 ms (default; 51⁄2 digits), or 1 second (61⁄2 digits). MIN = 0.01 seconds. MAX = 1 second.

[SENSe:]

FREQuency:APERture? [{(@<ch_list >)MINMAX}] PERiod:APERture? [{(@<ch_list>)MINMAX}]

Query the aperture time for frequency or period measurements on the specified channels. Returns a number in the form “+1.00000000E-01”.
