node[2].smua.trigger.measure.v(node[2].smua.nvbuffer
1)
node[2].smua.trigger.measure.action =
node[2].smua.ENABLE
Configure sweep voltage measurements.
Enable voltage measurements during the
sweep.
node[2].smua.trigger.count = 11
node[2].smua.trigger.arm.count = 6
Set trigger count to the number of steps
in the sweep.
Set arm count to six, the total number of
sweeps that will be run for all diodes.
node[2].tsplink.trigger[1].mode =
node[2].tsplink.TRIG_FALLING
node[2].tsplink.trigger[2].mode =
node[2].tsplink.TRIG_FALLING
Set TSP-Link trigger lines 1 and 2 to
send and receive falling edge trigger
signals.
node[2].tsplink.trigger[1].clear()
node[2].tsplink.trigger[2].clear()
Clear any latched triggers on TSP-Link
trigger lines 1 and 2.
node[2].smua.trigger.arm.stimulus =
node[2].tsplink.trigger[1].EVENT_ID
Configure sweep to start when signal
received on TSP-Link line 1.
node[2].tsplink.trigger[2].stimulus =
node[2].smua.trigger.SWEEP_COMPLETE_EVENT_ID
Configure System SourceMeter to output
trigger signal on TSP-Link line 2 when
sweep is complete.
end End of the function "Config SMU."
function runDiodeTest()
This function sequences the crosspoint
closures and triggering.
configSwitch() Call function to configure the Model 707B
or 708B.
configSMU()
node[2].smua.source.output = 1
node[2].smua.trigger.initiate()
scan.execute()
waitcomplete()
Call function that configures the System
SourceMeter instrument and turns on its
output.
Initiate the System SourceMeter so that it
is ready to sweep once a trigger signal is
received. Note that the output turns on
but no power is applied.
Initiate the System Switch to start a
foreground scan. Waits until Model
2635A finishes all measurements.
Remote operation pauses until all six
tests are complete. For other options on
running a scan, see
Using background
scans for longer scan lists (on page 5-
17).
node[2].smua.source.output = 0
channel.open("allslots")
Turn off the SMU output.
Open all crosspoints.
end
Ends the runDiodeTest function.
endscript
Ends the diodeTest script.
