“[SENSe[1|2]]:SWEep:OFFSet:POINts”: Changes the normally high output
level to low after the pre-arm count (SENSe:SWEep:OFFSet:POINts) has been
met. This would be used to determine when an arming event could occur
without getting an "Arm ignored" error due to the pre-arm count not being
satisfied. The level would not return to high again until either the next arm
cycle (if ARM:STARt:COUNt > 1) or the next INITiate command if this is the
last or only arm cycle. This source is only useful when pre-arm and post-arm
readings are being taken; it is allowed without error in post-arm measurements,
but is not of any real use.
“[SENSe[1|2]]:ROSCillator”: The reference oscillator clock is output. For all
reference oscillator sources except EXTernal, the resulting output signal is the
inverse of the actual reference (i.e. the output pulse goes low on the rising edge
of the reference oscillator). For SENSe:ROSCillator:SOURce EXTernal, the
output level goes low on the falling edge. Note that this signal begins being
output as soon as this feed is selected, and will be output continuously until the
feed source is changed to some other selection.
“TRIGger[:STARt|:SEQuence[1]]”: Outputs an approximately 25
nanosecond wide negative going pulse each time a convert pulse (TRIGger) is
sent to the A to D converter. Note that these pulses will also be generated when
data is read out of memory from the VINStrument:LBUS or
VINStrument:LBUS subsystems.
Note These pulses will also be generated when data is read out of memory from the
VINStrument:LBUS or VINStrument:VME subsystems.
