smuX.measure.analogfilter
X = SMU channel (a or b)
(Models 2635A and 2636A only)
Attribute Controls the use of an analog filter when measuring on the lowest current ranges.
TSP-Link
accessibility
This attribute can be accessed from a remote TSP-Link node.
Usage
option = smuX.measure.analogfilter -- Reads the filter setting.
smuX.measure.analogfilter = option -- Writes the filter setting.
option Indicates the filter setting
Where option is:
0 filter off
1 filter on
Remarks • This attribute engages an approximately 1Hz analog filter across the current range elements.
• The analog filter is only active when using the 1nA and 100pA measurement ranges.
Example Turns off the analog filter:
smua.measure.analogfilter = 0
smuX.measure.autorangeY
X = SMU channel (a or b)
Y = SMU measure function (v or i)
Where: v = voltage, i = current
Attribute Measurement auto range setting.
Default smuX.AUTORANGE_ON
TSP-Link
accessibility
This attribute can be accessed from a remote TSP-Link node.
Usage autorange = smuX.measure.autorangei -- Reads current measure auto
-- range.
smuX.measure.autorangei = autorange -- Writes current measure auto
-- range.
autorange = smuX.measure.autorangev -- Reads voltage measure auto
-- range.
smuX.measure.autorangev = autorange -- Writes voltage measure auto
-- range.
autorange Indicates whether measurement auto range is active.
Set autorange to one of the following values:
0 or smuX.AUTORANGE_OFF Disables measurement auto range.
1 or smuX.AUTORANGE_ON Enables measurement auto range.
Remarks • This attribute indicates the measurement auto range state. Its value will be
smuX.AUTORANGE_OFF when the SMU measure circuit is on a fixed range and
smuX.AUTORANGE_ON when it is in auto range mode.
• Setting this attribute to smuX.AUTORANGE_OFF puts the SMU on a fixed range. The fixed range
used will be the range the SMU measure circuit was currently using.
• Setting this attribute to smuX.AUTORANGE_ON puts the SMU measure circuit into auto range
mode. It will remain on its present measure range until the next measurement is requested.
Details See Range in Section 6.

Example Enables voltage measurement autoranging for SMU A:
smua.measure.autorangev = smua.AUTORANGE_ON
