(external trigger) and BUS
When the trigger mode is set to INT mode, JK2817N will repeat the test continuously.
When the trigger mode is set to MAN mode, ach time you press the [TRIGGER] key on the front
panel, JK2817N performs a test.
When the trigger mode is set to EXT mode, the HANDLER interface receives a positive pulse
signal every time
，
JK2817N performs a test.
When the trigger mode is set to BUS mode, the IEEE488 interface receives the "TRIGGER"
command once every time,JK2817N performs a test.BUS trigger mode can not be set in the front
panel of the instrument.
Note:When JK2817N/JK2811B is being tested, a trigger signal is received and the trigger signal is
ignored. Therefore, it is necessary to send the trigger signal when the JK2817N/JK2811B test is
completed.
Set the trigger mode to EXT mode when you need to trigger JK2817N/JK2811B from the selected
HANDER interface.
1) move the cursor key to the trigger domain. The soft key display area of the screen will display
the following soft keys.
● internal
●
Manual
● external
1) use the soft key to set the trigger mode of INT (internal), MAN (manual), EXT (external).
3.3.2 Automatic level control function
The automatic level control function can adjust the actual test level (the voltage at both ends of the
test piece or the current flowing through the test piece) to the value of the test level you set.
Using this function, the test voltage or current at both ends of the tested part can be kept constant.
When the automatic level control function is adopted, the test level can be set as follows:
Constant voltage setting range:10 mVrms to 1Vrms
Constant current setting range:100 µArms to 10 mArms
Note: When the constant level function is valid, if the level setting exceeds the above range, the
constant level function will be automatically set to OFF.The current level is generally used as a
non constant level value.
Automatic level control function setting operation steps
Perform the following steps to set the constant level function to ON or OFF..
1) move the cursor to the constant level domain. The soft key area of the screen displays the
following soft keys.
●
ON
● OFF
2) press the ON soft key and turn on the automatic level control function ON.
