------------------ Keithley TSP Function ------------------
function Diode_Fwd_Char_Pulse(ilevel, start, stop, ton, toff, steps) --Configure instrument
to source a
--bias current,and perform a pulsed current sweep from start to stop in a user-defined
number of steps.
--Each pulse is on ton (s) and off toff (s) and returns to the bias level during the toff
time.
--Returns measured voltage and current values.
--Global variables
local l_irange = 100E-2 --Current source range
local l_ilevel = ilevel --Initial source value
local l_vcmpl = 6 --Source compliance
--Shared local variables
local l_nplc = 0.1 --Integration rate of measurement
--Local sweep variables
local l_start = start --Sweep start current
local l_stop =
local l_steps = steps --Number of steps in sweep
local l_delay = 0.001 --Source delay
local l_ton = ton --Pulse on duration
local l_toff = toff --Pulse off duration
local l_tonwm --Adjusted Pulse on duration to accomodate Measurement Duration
--Default values and level check
if (l_ilevel == nil) then --Use default value
l_ilevel = 0
end --if
if (l_ilevel > 1E-1) then --Coerce value
l_ilevel = 1E-1
end --if
stop --Sweep stop current
