4.1.7 Rate (Integration Time)

Definition
Integration time is the period of time the analog-to-digital (A/D)
converter takes to sample the input signal. The integration time feature
allows you to optimize either the speed or the resolution, as well as the
noise rejection and the accuracy of the measurement. The unit of the
integration time is in PLC (power line cycles). One PLC for 60 Hz is 16.67
ms, and for 50 Hz is 20 ms.
There are 4 different integration times in M3500A for you to select from:
0.02, 0.1, 1 and 10 PLCs.
Default
For DCV, DCI, and resistance measurement, the default integration time
is 1 PLC. The user selected value is stored in a volatile memory and the
default value will be restored when the meter is power-off.
How to set the integration time:
You can set the integration time either through the front panel operation
or through the remote interface operation.
Front Panel Operation
Integration time is set indirectly when you select the measurement
resolution. Please refer to chapter 4.1.3 for details about how to set
resolution or the digits. Table 4-1 on page 51 shows the relationship
between the resolution and the integration time.
Remote Interface Operation
Use the following commands on your PC terminal to set the resolution.
CONFigure:< function> <range>, <resolution>
MEASure:< function>? <range>, <resolution>
SENSe:< function>:RESolution <resolution>
Or you can set integration time directly by the following commands.
