Gate Time
Applies to frequency and period measurements only.
The multimeter provides four choices of gate time (also called aperture) for
frequency or period measurements. The gate time selection affects resolution
as shown below.
• Front Panel Operation: Press and then press .
CONFIGURE > FREQENCY > GATE TIME or
CONFIGURE > PERIOD > GATE TIME
Select a gate time in seconds (.001, .01, .1, or 1), and then step through or exit
the menu.
• Remote Interface Operation: The following commands set the gate time
(aperture) for frequency or period measurements:
[SENSe:]FREQuency:APERture {<
seconds
>>MIN>MAX>DEF}
[SENSe:]PERiod:APERture {<
seconds
>>MIN>MAX>DEF}
The following commands query the gate time setting:
[SENSe:]FREQuency:APERture? [{MIN>MAX}]
[SENSe:]PERiod:APERture? [{MIN>MAX}]
Refer to the Agilent 34410A/11A/L4411A Programmer’s Reference Help for
a complete description and syntax for these commands.
