smuX.nvbufferY.timestampresolution
X = SMU channel (a or b)
Y = NV buffer (1 or 2)
Attribute Timestamp resolution.
Default 1e-6
TSP-Link
accessibility
This attribute can be accessed from a remote TSP-Link node.
Usage tsres = smuX.nvbufferY.timestampresolution --Reads resolution.
smuX.nvbufferY.timestampresolution = tsres --Writes resolution.
tsres Timestamp resolution in seconds.
Remarks • Assigning to this attribute sets the resolution for the timestamps. Reading this attribute returns
the timestamp resolution value.
• The finest timestamp resolution is 0.000001 seconds (1µs). At this resolution, the reading
buffer can store unique timestamps for up to 71 minutes. This value can be increased for very
long tests.
• When setting this value it will be rounded to an even power of 2µs.
Details See Reading buffers in this section and in Section 7.
Also see smuX.measure.overlappedY, smuX.measure.Y, smuX.nvbufferY
Example Set the timestamp resolution for SMU A Buffer 1 to 8µs:
smua.nvbuffer1.timestampresolution = 0.000008
smuX.reset
X = SMU channel (a or b)
Function Turns off the output and resets the SMU to the default settings.
TSP-Link
accessibility
This function can be accessed from a remote TSP-Link node.
Usage smuX.reset()
Remarks Returns the SMU to the default settings.
Also see reset
smuX.savebuffer
X = SMU channel (a or b)
Function Saves one SMU dedicated reading buffer to internal memory (there are two dedicated reading
buffers per SMU).
TSP-Link
accessibility
This function can be accessed from a remote TSP-Link node.
Usage smuX.savebuffer(nvbuffer)
nvbuffer This may be either smua.nvbuffer1 or
smua.nvbuffer2 if smuX is smua. It is either
smub.nvbuffer1 or smub.nvbuffer2 if
smuX is smub.
Remarks • When the unit is turned off and back on, the dedicated reading buffers will be restored to their
last saved values.
