Comments • Executable when initiated: No
• Coupled Command: Yes. This command is coupled to
TRIGger:STARt:COUNt, SENSe:SWEep:POINts, ARM:STARt:COUNt,
ARM:STARt:DELay, and MEMory:BATTery:STATe.
• Readings which are taken before the arm event occurs are called "pre-arm"
readings. Readings taken after the arm event are called "post-arm" readings.
• The INITiate command "triggers" pre-arm readings. If any arming events occur
before the pre-arm count is satisfied, the arms are ignored and an error occurs.
When the pre-arm count is satisfied and a legal arm event occurs, post-arm
sampling begins. The remaining number of TRIGger:STARt:COUNt
(SENSe:SWEep:POINts) readings are then taken.
• If pre-arm readings are not 0, then there must be at least 7 post-arm readings.
Therefore, (SENSe:SWEep:POINts + SENSe:SWEep:OFFSet:POINts) must be
≥ 7. (Note that in the previous equation, :OFFSet:POINts will be a negative
number).
• Pre-arm reading count values between -3 and 0 will be rounded to -3 or 0,
whichever is closer to the specified count.
• If an ABORt or power failure occurs during a sequence of measurements, the
digitizer will return (FETCh?) or recover (FETCh:RECover?) between one and
TRIGger:STARt:COUNt number of readings. Because the digitizer processor
does not know when the arm occurs, the readings returned may be pre-arm only,
post-arm only, or a combination of both. If less than TRIGger:STARt:COUNt
readings have been taken, then that number of readings are returned. If greater
than TRIGger:STARt:COUNt readings have been taken, then
TRIGger:STARt:COUNt readings are returned.
