Programming Basics
Getting Started
To Set the Integration Time
To adjust the balance of the measurement accuracy and the measurement speed,
change the integration time or the number of averaging samples of the A/D
converter (ADC) by using the AV command. The AV command is compatible with
the AV command of the Keysight 4142B.
For accurate and reliable measurement, set the integration time longer or set the
number of samples larger. For details about the integration time settings, refer to
Chapter 4, “Command Reference.”
The Keysight E5270B has the following two types of the A/D converter. Use the
AAD command to select the type of ADC, and use the AIT command to set the
integration time or the number of samples.
Example The following example sets the number of samples to 10 for the A/D converter
(high-speed ADC for the Keysight E5270B).
OUTPUT @E5270;"AV 10,1"
The following example is for the Keysight E5270B, and sets the power line cycle
mode (PLC) for both the high-speed ADC and the high-resolution ADC. And
channel 1 uses the high-resolution ADC and other channels use the high-speed
ADC.
OUTPUT @E5270;"*RST"
OUTPUT @E5270;"AIT 0,2,1"
OUTPUT @E5270;"AIT 1,2"
OUTPUT @E5270;"AAD 1,1"
Type of ADC Description
High-speed ADC Effective for the high speed measurement. In the multi
channel sweep measurement mode (MM16), multiple
measurement channels can perform synchronous
measurements.
The number of averaging samples must be set by the
AIT or AV command.
High-resolution ADC Effective for the accurate measurement. Cannot be used
for the pulsed measurement channel and the
simultaneous measurement channel.
The integration time must be set by the AIT command.
