Smux.measure.adc - Keithley 2651A Reference Manual

Section 7: Command reference
Details
Reading buffers can be created and allocated dynamically using this function. Use bufferSize to designate the
number of readings the buffer can store.
Dynamically allocated reading buffers can be used interchangeably with the smuX.nvbufferY buffers.
A reading buffer can be deleted by setting all references to the reading buffer equal to nil, then running the
garbage collector (see the collectgarbage() function in
Example
mybuffer2 = smua.makebuffer(200)

Details
When making measurements, the SMU uses one of two types of analog to digital converters. This attribute
controls which analog to converter is used.
Example
smua.measure.adc = smua.ADC_FAST

Recall
The analog to digital (A/D) converter used for measurements. Set to one of the
following:
0 or smuX.ADC_INTEGRATE: Integrating A/D converter
1 or smuX.ADC_FAST: Fast A/D converter
Source-measure unit (SMU) channel (for example, smua.measure.adc applies to
SMU channel A).

Standard libraries
Creates a 200 element reading buffer (mybuffer2)for
SMU channel A .
