About the function of DOUBLE SWEEP option CS-801
It explains the usage and the function of this option.
It is also possible to measure by the SWEEP function when measuring in this instrument. Four
kinds of SWEEP functions are provided when dividing by the action (Refer to Section 3.8.3.).
The DOWN UP action in four kinds can be actioned by DOUBLE SWEEP option.
DOUBLE SWEEP is an optional function to observe hysteresis etc. when the Ic-Vce characteristic
etc. of the semiconductor devices are measured. The difference between the characteristic when
SWEEP is done in the direction of UP and the characteristic when SWEEP is done in the direction of
DOWN can be observed in a short time as shown in the figure below.
(The example of the figure below
is a drawn image figure because it explains to the last like there is an extreme difference.)
Do SWEEP in the direction of UP up to the set value of SWEEP END VARIABLE from the VARIABLE
set value in SWEEP Start point A to Turning point B as shown in the figure below.
In addition, turn as it is continuously from Turning point B, and do SWEEP in the direction of DOWN
up to the VARIABLE set value to SWEEP Start point A.
It is necessary to set COLLECTOR SWEEP DOUBLE available by the APPLICATION menu to make
the function of this option available. Refer to Section 3.11.7.4 for the setting.
Moreover, it is necessary to set the item etc. of following (1) to (3) beforehand by the ACQUIRE menu
about the action of this option. Refer to Section 3.7.5 for details of the setting item.
(1) SWEEP TYPE: Select DOWN UP from four kinds of UP, DOWN, CUSTOM, and DOWN UP.
(2) SWEEP END VARIABLE: Setting value of turn of DOUBLE SWEEP (%)
(3)
Setting value of VARIABLE: Setting value of start of DOUBLE SWEEP (%)
