Reading buffer commands
The following table summarizes commands associated with the reading buffers. See the
command reference
Reading buffer commands*
Command
Commands to save/clear readings:
smuX.savebuffer(smuX.nvbufferY)
smuX.nvbuffer1.clear()
smuX.nvbuffer2.clear()
mybuffer = smuX.makebuffer(n)
mybuffer = nil
savebuffer(smuX.nvbuffer1,"csv",
"mybuffer.csv")
Commands to store readings
smuX.measure.count = count
smuX.measure.overlappedi(rbuffer)
smuX.measure.overlappediv(ibuffer,
vbuffer)
smuX.measure.overlappedp(rbuffer)
smuX.measure.overlappedr(rbuffer)
smuX.measure.overlappedv(rbuffer)
smuX.measure.v(rbuffer)
smuX.measure.i(rbuffer)
smuX.measure.iv(ibuffer,
vbuffer)
smuX.measure.r(rbuffer)
smuX.measure.p(rbuffer)
smuX.trigger.measure.v(rbuffer)
smuX.trigger.measure.i(rbuffer)
smuX.trigger.measure.r(rbuffer)
smuX.trigger.measure.p(rbuffer)
smuX.trigger.measure.iv(ibuffer,
vbuffer)
Commands to access readings:
printbuffer(start_index,
end_index,
st_1, st_2, ... st_n)
* smuX: For Models 2601B, 2611B, and 2635B, this value is smua (SMU Channel A); for Models 2602B, 2604B, 2612B,
2614B, 2634B, and 2636B, this value can be smua (for SMU Channel A) or smub (for SMU Channel B).

Series 2600B System SourceMeter® Instrument Reference Manual
(on page 7-1) for detailed reading buffer command information.
Description
Saves the reading buffer to the nonvolatile memory on the Series
2600B.
Clears buffer 1.
Clears buffer 2.
Creates a dynamically allocated buffer for n readings.
Deletes the dynamically allocated buffer.
Saves the reading buffer to the USB flash drive.
The number of measurements to acquire.
Takes current measurements; stores readings in rbuffer.
Takes both current and voltage measurements; stores current
readings in ibuffer and stores voltage readings in vbuffer.
Takes power measurements; stores readings in rbuffer.
Takes resistance measurements; stores readings in rbuffer.
Takes voltage measurements; stores readings in rbuffer.
Takes voltage measurements; stores readings in rbuffer.
Takes current measurements; stores readings in rbuffer.
Takes both current and voltage measurements; stores current
readings in ibuffer and stores voltage readings in vbuffer.
Takes resistance measurements; stores readings in rbuffer.
Takes power measurements; stores readings in rbuffer.
Configures voltage measurements to be made during a sweep
including the location where readings will be stored (rbuffer).
Configures current measurements to be made during a sweep
including the location where readings will be stored (rbuffer).
Configures resistance measurements to be made during a sweep
including the location where readings will be stored (rbuffer).
Configures power measurements to be made during a sweep
including the location of readings where readings will be stored
(rbuffer).
Configures both current and voltage measurements to be made
during a sweep including the location of where readings will be
stored; current readings will be stored in ibuffer and voltage
readings will be stored in vbuffer.
Prints data from buffer subtables: start_index (starting index of
values to print).
end_index (ending index of values to print).
st_1, st_2, ... st_n (subtables from which to print, each
separated by a comma).
