## .. DSWEEP XXXXX U.start ........mV U.step ........mV
U.end ........mV Sweep rate XXXXXXXXmV/s
Function Voltage sweep without measured value recording (Dummy Sweep).
Parameter Range; Default value / Meaning
t/s display only
Time for voltage step
In the line time (which can not be edited), the time for the voltage
sweep is displayed and is calculated as follows:
(U.end - U.start)
Sweep time = –––––––––––––––––––––
Sweep rate
U.start -3000...3000 mV; -
Initial voltage
Initial voltage for the voltage sweep.
U.end -3000...3000 mV; -
Final voltage
Final voltage for the voltage sweep. This voltage is retained after the
end of the sweep until a new voltage is applied or until it is switched off
by
ØMEAS or END in the main program on the "OP.SEQUENCE" page.
U.step 2, 4, 6, 8, 10, 12 mV; 6 mV
Voltage step
Voltage step for direct current ramp.
Sweep rate display only
Ramp slope
Here, the slope of the direct current ramp is displayed in mV/s. It is
calculated as follows:
U.step
Sweep rate = ––––––––
t.step
The parameter t.step originates from the measurement mode, which
must be entered before the SWEEP instruction.
