Step generator SWEEP
The step generator SWEEP is available when the step generator is set to PULSE and
HORIZONTAL source is set to BASE-EMITTER (see Section 3.9.1). SWEEP STEPS can be
set only when the step generator SWEEP function is available (see Section 3.8.3).
Example of SWEEP STEPS display
NUMBER OF STEPS
It sets the number of steps (range: 0 to 20 steps)
SWEEP STEPS setting range
One step of the step generator can be divided into 1 to 200 measurement points using 1-2-5 step
(1, 2, 5, 10, 20, 50, 100, 200).
However, the maximum number of measurement points in all steps (SWEEP STEPS setting value)
shall not exceed 1000.
Starting SWEEP measurement
When the step generator is in PULSE and HORIZONTAL source is in BASE-EMITTER, pressing
SWEEP key starts SWEEP measurement.
Operation states are displayed during SWEEP measurement as shown below:

Stopping and restarting SWEEP measurement
When the data up to SWEEP STEPS setting value is acquired, the measurement stops and the
state returns to STOP. If SWEEP measurement is to be done again, press SWEEP key.
Memo
For example, if NUMBER OF STEPS(6, the number of measurement points can be the minimum of 6 (i.e., 1
point per step) up to the maximum of 600 (i.e., 100 points per step). Since the next of 100 measurement point
setting is 200, the total number of points in all steps (6) is 1200. Therefore, the maximum points in this case
should be 100.
Voltages from (206mV (offset
voltage) to 1.206V (200mV
( 5 ( 206mV) are swept at
1000 points.
