4339B ARM Subsystem
:ARM[:SEQuence1][:LA Y er]:DELay <numeric value> [MS j S]
Sets the DUT charging time before a DUT is measured. The charge time denes the waiting
time when the 4339B triggered a measurement to when the measurement will actually start.
The test voltage is applied during this time .
<numeric value> is ,
Range Resolution
0 s Charge Time < 10 s 1 ms
10 s Charge Time < 100 s 10 ms
100 s Charge Time 999 s 100 ms
:ARM[:SEQuence1][:LA Y er]:SOURce fBUS j EXT ernal j MANual j IMMediateg
Sets the sequence measurement mode to ON or OFF , and selects the source for the ARM event
detector . When the ARM event is detected, the 4339B enables the output test voltage and
applies the test voltage to DUT . After charge-time wait, 4339B move from the ARM event
detection state to the TRIG event detection state .
When BUS , EXTernal , or MANual is selected as the ARM source , the 4339B automatically
enables the test voltage output at the time an ARM event is detected, and applies the test
voltage to the DUT . After the measurement, the 4339B automatically turns OFF the test
voltage output. When IMMediate is selected, the ARM event has no eect on test voltage
output enabling or disabling, you must control test voltage output.
Only one trigger source can be specied at a time for a given event detector . The available
trigger sources are:
P arameter Measurement
Sequence
Trigger Source
BUS
ON
GET or *TRG commands
EXTernal An external trigger signal from external trigger terminal
MANual The front-panel key .
IMMediate OFF No waiting for a ARM event to occur .
( The 4339B immediately advances to the TRIG event detection
state .)
Query response format is BUS , MAN , INT , or IMM .
