Programming Basics
Programming Tips
To Optimize the Measurement Range
The most effective way to improve measurement speed is to reduce the number of
range changes. The limited auto ranging mode is more effective than the auto
ranging mode. The fixed range mode is the most effective.
Check the typical value of the measurement data, select the optimum range, and
perform measurement using the fixed range mode.
To Optimize the Integration Time
For best reliability and repeatability of the measurement data, the integration time or
the number of averaging samples of the A/D converter must be increased. This
increases the measurement time.
A long integration time and numerous samples are required for low current/ voltage
measurements. However, the values can be decreased for medium or high
current/voltage measurements. Enter the following commands:
AV Sets the number of averaging samples of the A/D converter. This
command is compatible with the AV command of the Keysight 4142B.
AAD Selects the type of the A/D converter (high-speed ADC or
high-resolution ADC) of the Keysight E5270B.
AIT Sets the integration time of the high-resolution ADC or the number of
averaging samples of the high-speed ADC of the Keysight E5270B.
The AIT command covers the function of the AV command. The last
command setting is available for the measurement.
For more information regarding these commands, refer to Chapter 4, “Command
Reference.” The AAD/AIT commands are available only for the Keysight E5270B.
To Disable the ADC Zero Function
This information is effective only for the Keysight E5270B and when the high
resolution A/D converter is used for the measurement. If measurement speed is
given top priority or is more important than reliability, disable the ADC zero
function by sending the
AZ 0
command. This roughly halves integration time.
NOTE The ADC zero function is the function to cancel offset of the high resolution ADC.
This function is especially effective for low voltage measurements.
