Keithley Series 2600 Application Manual page 118

(1) Keithley Model 2636 System Sourcemeter instrument (Required for low current
measurement)
(1) Crossover Ethernet Cable
(1) SD210 N-Channel MOSFET
- Connect the single-channel SourceMeter instrument to the dual-channel master using a
crossover Ethernet cable.
- Connect the test fixture to both units using appropriate cables.
- Turn on the SourceMeter instrument and allow the unit to warm up for two hours for rated
accuracy.
Configure the TSP-Link communications for each instrument:
Slave: A single-channel instrument such as the Model 2601, 2611, or 2635.
1. Press the MENU key to access MAIN MENU.
2. Select the COMMUNICATION menu. (Skip this step if the Series 2600 instruments
used have firmware Revision 1.4.0 or later installed.)
3. Select the TSPLINK_CFG menu. (If the Series 2600 instruments used have firmware
Revision 1.4.0 or later installed, the menu name should be TSPLINK.)
4. Select the NODE menu.
5. Set the NODE number to 2 and press ENTER.
Master: A dual-channel instrument such as the Model 2602, 2612, or 2636.
1. Press the MENU key to access MAIN MENU.
2. Select the COMMUNICATION menu. (Skip this step if the Series 2600 instruments
used have firmware Revision 1.4.0 or later installed.)
3. Select the TSPLINK_CFG menu. (If the Series 2600 instruments used have firmware
Revision 1.4.0 or later installed, the menu name should be TSPLINK.)
4. Select the NODE menu.
5. Set the NODE number to 1 for the Master and press ENTER.
6. Select the TSPLINK_CFG menu. (If the Series 2600 instruments used have firmware
Revision 1.4.0 or later installed, the menu name should be TSPLINK.)
7. Select the RESET to initialize the TSP-Link.
Running this script creates functions that can be used to measure the common source
characteristics of an N-channel MOSFET with substrate bias. The default values are for an
N-channel MOSFET type SD210.
The functions created are:
1. FET_Comm_Source_Vsb(vgsstart, vgsstop, vgssteps, vdsstart, vdsstop,
vdssteps, vsbsource)
--Default values vgsstart = 0, vgsstop = 10V, vgssteps = 5, vdstart = 0V,
vdstop = 10V,
--vdsteps = 100, vsbsource = -1V
2. Print_Data(vgssteps,vdssteps, vds_data,Id_data, vgs_data, vsbsource)
See detailed information listed in individual functions.
