Command Reference
AAD
AAD
This command is used to specify the type of the A/D converter (ADC) for each
measurement channel.
Execution
Conditions
Enter the AIT command to set up the ADC.
Syntax AAD chnum,type
Parameters chnum : SMU measurement channel number. Integer expression. 1 to 10 or 101
to 1001. See Table 4-1 on page 4-16.
type : Type of the A/D converter. Integer expression. 0, 1, or 2.
0: High-speed ADC for high speed DC measurement. Initial setting.
1: High-resolution ADC. For high accurate DC measurement.
Not available for the HCSMU, HVSMU, and MCSMU.
2: High-speed ADC for pulsed-measurement
The pulsed-measurement ADC is automatically used for the pulsed spot, pulsed
sweep, multi channel pulsed spot, multi channel pulsed sweep, or staircase sweep
with pulsed bias measurement, even if the AAD chnum,2 command is not executed.
The pulsed-measurement ADC is never used for the DC measurement. Even if the
AAD chnum,2 command is executed, the previous setting is still effective.
Example
Statements
OUTPUT @B1500;"AAD 1,0"
OUTPUT @B1500;"AAD 1,1"
AB
The AB command aborts the present operation and subsequent command execution.
This command stops the operation now in progress, such as the measurement
execution, source setup changing, and so on. But this command does not change the
present condition. For example, if the B1500 just keeps to force the DC bias, the AB
command does not stop the DC bias output.

Example
Statements
OUTPUT @B1500;"AB"
