3.8 Setting measurement
There are three measurement modes: REPEAT, SINGLE, and SWEEP. The upper part on the
screen shows the current measurement mode.
3.8.1 REPEAT
Pressing REPEAT key allows this instrument to change to REPEAT mode; i.e., signals are
generated from the step generator at the specified interval and measurement is repeated.
3.8.2 SINGLE
Pressing STOP/SINGLE key allows this instrument to change to SINGLE mode; i.e., the signal
with the set number of steps is generated from the step generator once and measurement is done.
When the measurement ends, this instrument changes to STOP state. In addition, use of this key
allows REPEAT measurement and SWEEP measurement to end and this instrument to change to
STOP state.
In STOP state, output and measurement with the step generator stop. For collector supply output,
the output stops at the time of AC, SINE (full-wave rectified), or DC. The collector supply in
LEAKAGE always generates the setting voltage.
3.8.3 SWEEP
Conditions for collector supply SWEEP
The collector supply SWEEP function is available if the step generator is set to PULSE and
HORIZONTAL source is set to COLLECTOR. In this case, selection of SWEEP TYPE from
DOWN/UP/CUSTOM/DOWN UP
Note
allows operations as shown below:
- DOWN: It sweeps the range from VARIABLE setting value when SWEEP starts to 0.0
%
.
- UP: It sweeps the range from 0.0
%
to VARIABLE setting value when SWEEP starts.
- CUSTOM: It sweeps the range from VARIABLE setting value when SWEEP starts to the setting value of
SWEEP END VARIABLE.
- DOWN UP
Note
:
Sweep from the VARIABLE set value in point that starts SWEEP to the set value of SWEEP END
VARIABLE. In addition, turn as it is continuously, and sweep up to the VARIABLE set value in point
that starts SWEEP in the opposite direction.
In any case above, after SWEEP measurement ends, VARIABLE setting value returns to the value when
SWEEP starts.
Note ) When the use of DOUBLE SWEEP optional CS-801 and this function have been turned on, DOWN UP of
SWEEP TYPE can be selected. Refer to section 3.11.7 for details of this option CS-801.
Conditions for step generator SWEEP
If the step generator is set to PULSE and HORIZONTAL source is set to BASE-EMITTER, the step
generator SWEEP is available. In this case, the range from the offset voltage up to the maximum
value of the step signal (voltage per step
×
number of steps
+
offset voltage) is automatically swept
using the set number of steps for measurement.
SWEEP start
When SWEEP is available, pressing SWEEP key allows SWEEP to start.
