3.3.1
Trigger mode
There are 4 trigger modes on U2836: INT, MAN, EXT and DUT.
When the trigger mode is set as INT, U2836 will make sequential and repeated
tests.
When the trigger mode is set as MAN, press [TRIG] once, U2836 will make one
test.
When the trigger mode is set as EXT, once the HANDLER interface receives a
positive impulse, U2836 will execute one measurement.
When the trigger mode is set as DUT, once the test fixture receives a component,
U2836 will execute one measurement.
When the trigger mode is set as BUS, once the IEEE 488 interface receives a
TRIGGER command, U2836 will execute a test. The BUS mode cannot be set on
the front panel.
———————————————————————————————————————
Note: In the process of testing, when U2836 receives a trigger signal, it will be
ignored. So the trigger signal should be sent after the test is done.
When optional HANDLER interface triggers U2836, the trigger mode is set as
EXT.

Operation steps for the trigger mode setup
Execute the operation of other trigger modes except BUS trigger. If BUS trigger
mode is necessary, then use IEEE4888 interface to send
TRIGger:SOURce BUS
command.
1)
Move the cursor to the
TRIG
zone, the following soft keys will be displayed:
INT
MAN
EXT
DUT
2)
Use above soft keys to set the trigger mode.
3.3.2
Average
The AVERAGE function can calculate the average value of two or more test results.
The average times can be set from 1 to 255 with an increase or decrease of 1.
Operation steps for setting test average times.
1)
Move the cursor to the
AVG
zone, the following soft keys are displayed.
INCR
+
This key is used to increase the average times.
DECR
-
This key is used to decrease the average times.
