“ARM[:START|:SEQuence[1]]”: Changes the normally high output level to
low as soon as an ARM event (ARM:STARt:SOURce) is processed. The level
remains low until the ARM cycle is completed by TRIGger:STARt:COUNt
readings being taken. This signal begins at the detection of the arm event, and
does not include any programmed delay (ARM:STARt:DELay). The expected
use of this signal is to allow a master module to detect an arm event and then
arm other modules by using this signal.
“READy”: Changes the normally high output level to low whenever the trigger
system is initiated. If multiple groups (ARM:STARt:COUNt > 1) of pre-arm
and post-arm measurements are being taken, the level changes back to high
while the microprocessor changes which memory segment will receive the next
burst of data, and then the level goes low again when the HP E1429 is again
initiated. If only one burst of pre-arm and post-arm readings are taken, or if all
data is post-arm, then the level changes back to high when the measurement is
complete.
