smuX.measure.analogfilter
This attribute controls the use of an analog filter when measuring on the lowest current ranges. This attribute is
available on the Models 2634B/2635B/2636B only.
Type TSP-Link accessible Affected by Where saved Default value
Attribute (RW) Yes
Instrument reset
SMU reset
Recall setup

Usage
option = smuX.measure.analogfilter
smuX.measure.analogfilter = option
option
Enables or disables the analog filter: set to one of the following:
0: Filter off
1: Filter on
X
Source-measure unit (SMU) channel (for example,
smua.measure.analogfilter applies to SMU channel A)
Details
This attribute engages an approximately 1 Hz analog filter across the current range elements.
The analog filter is only active when using the 1 nA and 100 pA measurement ranges.
Example
smua.measure.analogfilter = 0
Turns off the SMU channel A analog filter.
