6243/44 DC Voltage Current Source/Monitor Operation Manual
4.4.2 Pulse Sweep
4-17
<Explanations of Illustrations>
• Bias values are output before sweep start and after sweep finish.
• When a start trigger is received, the start value is output.
• After receiving a start trigger, the 6243/44 waits for the Hold time + Source Delay time and then the
measurement starts.
• When the trigger mode is internal, after completion of measurement and period, the 6243/44 waits
for the Source Delay time and then outputs the next Step value or the Bias Value (End Value). When
the trigger mode is external, this takes place after the Step Trigger is input.
• After the next Step Value is output, the 6243/44 waits for the Measure Delay time and then the mea-
surement starts.
4.4.2 Pulse Sweep
In the same way as the staircase sweep (Section 4.4.1), linear pulse sweeps or log pulse sweeps can be
selected for the sweep type and one-way sweep or round-trip sweep can be selected with Reverse ON/OFF.
Table 4-6 Sweep Types for Pulse Sweep
Sweep type Output waveform Number of steps, No. K output value
Linear pulse sweep
Reverse-OFF
No. K output = Start value + (K-1) ï‚´ (Step value)
Number of steps = | Stop value - Start value | /Step value + 1
(Maximum 5000)
Linear pulse sweep
Reverse-ON
Log pulse sweep
Reverse-OFF
No. K output = (Start value) ï‚´ 10 K/n
n: Number of divisions per decade
• Start value, Stop value0
| Start value | ï‚£ | Stop value |
Start value polarity = Stop value polarity
