Set up the solar cell I-V sweep using TSP commands
The following TSP code is designed to be run from Keithley Instruments Test Script Builder (TSB).
TSB is a software tool included on one of the CD-ROMs that came with your Model 2450. You can
install and use TSB to write code and develop scripts for TSP-enabled instruments. Information
about how to use TSB is in the online help for TSB and in the “Introduction to TSP operation” section
of the
Model 2450 Reference Manual
.
To use other programming environments, you may need to make changes to the example TSP code.
By default, the Model 2450 is configured to use the SCPI command set. You must select the TSP
command set before sending TSP commands to the instrument.
To enable TSP commands:
1. Press the
MENU
key.
2. Under System, select
Settings
.
3. Select the button next to Command Set and select
TSP
.
4. You are prompted to reboot. Select
Yes
.
In this application, a linear voltage sweep is configured to output voltage from 0 V to 0.53 V in 56
steps. The instrument measures the resulting current from the solar cell during the sweep.
