[SENSe:]COUNter:GATE:TIME[:INTernal]
Syntax
[SENSe:]COUNter:GATE:TIME[:INTernal] {<time>|MIN|MAX|DEF}, (@<ch_list>)
[SENSe:]COUNter:GATE:TIME[:INTernal]? [{MIN|MAX},] (@<ch_list>)
Description
This command sets the internal gate time for initiated measurements on the specified counter channels on the 34950A Digital I/O Module (each bank has it's own Gate input line). The specified gate time is the measurement aperture during which the signal data is gathered. For repetitive signals, longer gate times will lead to increased resolution for frequency, period, pulse width, and duty cycle measurements.
Used With:
34950A Digital I/O Module
Parameters

Name |
Type |
Range of Values |
Default Value |
|
<time> |
Numeric |
Desired gate time between 100 ns and 10 seconds, with 50 ns resolution. MIN = 100 ns, MAX = 100 seconds |
1 ms |
|
<ch_list> |
Numeric |
One or more counter channels in the form (@sccc).
|
This is a required parameter |
Remarks
Changing the gate time while an initiated measurement is in progress (see [SENSe:]COUNter:INITiate command) is not allowed.
The selected gate time is stored in volatile memory and will be set to 1 ms when power is turned off or after a Factory Reset (*RST command).
Return Format
The query command returns the gate time in the form "+1.00000000E-03" for each channel specified. Multiple responses are separated by commas.
Examples
The following command sets the gate time to 200 ms on counter channels 301 and 302 on the module in slot 3.
COUN:GATE:TIME 200E-3,(@3301,3302)
The following query returns the threshold voltage settings on counter channels 301 and 302 on the module in slot 3.
COUN:GATE:TIME? (@3301,3302)
Typical Response: +2.00000000E-01,+2.00000000E-01
