Program 3B. Diode Characterization Log Sweep
--[[
Diode_Fwd_Char_Log(): USES TABLES
This program performs a log sweep forward characterization test on a diode and prints
data.
Required equipment:
(1) Single-channel Keithley Series 2600 System SourceMeter instrument
(1) Silicon diode or equivalent
Running this script creates functions that can be used to measure the IV characteristics
of diodes.
The functions created are:
1. Diode_Fwd_Char_Log(ilevel, start, stop, points) --Default values ilevel =
0s,
--start = 1ua, stop = 10ma
--points = 10
2. Print_Data(steps,volt,curr)
See detailed information listed in individual functions
To run:
1) From Test Script Builder
- Right-click in the program window, select “Run as TSP”
- At the TSP> prompt in the Instrument Control Panel, type Diode_Fwd_Char_Log()
2) From an external program
- Send the entire program text as a string using standard GPIB Write calls.
