.
Install a device (Power FET, LED array, etc .) in the appropriate
6 .
transistor socket of the test fixture .
Now, we must send the code to the instrument . The simplest
7 .
method is to right-click in the open script window of TSB,
and select ‘
Run as TSP file
’ . This will compile the code and
place it in the volatile run-time memory of the instrument .
To store the program in non-volatile memory, see the “TSP
Programming Fundamentals” section of the Series 2600 Refer-
ence Manual .
Once the code has been placed in the instrument run-time
8 .
memory, we can run it at any time simply by calling the func-
tion ‘
RunHighVoltage(sourcev, points)
’, where
sourcei
is the desired voltage value and
points
is the
number of voltage measurements .
In the program ‘
9 .
KI2602Example_High_Voltage.tsp
’, the func-
tion
RunHighVoltage(sourcev,points)
is created .
sourcev
•
represents the voltage value delivered to the
DUT Note that the actual voltage value programmed for
each SMU is half the sourcev value .
points
•
represents the number of voltage measurements
acquired
If you wanted to source 80V total to the DUT and collect 100
voltage measurements, you would send
RunHighVoltage(80, 100)
to the instrument .
The sources will be enabled, and the voltage source and cur-
10 .
rent measurements will be executed .
Once the measurements have been completed, the data will
11 .
be presented in the Instrument Console window of TSB .
6.2.3 Program 16 Description
After the SMUs are returned to default conditions, SMUA is con-
figured as follows:
Source V
•
1A compliance, autorange
•
1 NPLC integration rate
•
sourcev
•
: DUT voltage
points
•
: Number of points to measure
Next, SMUB is set up to operate in the following manner:
Source I
•
1A, autorange
•
sourcev
•
: DUT voltage
After the instrument is set up, the outputs are zeroed and enabled .
Each SMU performs a DC voltage source and SMUA begins to
measure the current . When the data collection has reached the
desired number of points, the outputs are disabled and the cur-
rent data is printed to the Instrument Console of TSB .
Warning:
If either SMU reaches a compliance state, the instru-
ment, device, or both could be damaged. To avoid
this, set the compliance value to the maximum for
your instrument and avoid shorting the SMUs when
in Voltage Source mode.
