TRIGger[:STARt]:COUNt

Comments Executable when initiated: No

Coupled Command: This command is coupled to SENSe:SWEep:POINts, SENSe:SWEep:OFFSet:POINts, ARM:STARt:COUNt, and MEMory:BATTery:STATe.

TRIGger:STARt:COUNt values between 1 and 7 will be rounded to 1 or 7, whichever is closer to the specified count.

If the count is set to INFinity or 9.9E+37, the ABORt command must be used to return the trigger system to the idle state before any readings taken may be read from memory. Due to this, the READ? command can not be used when TRIGger:STARt:COUNt is set to INFinity, attempts to do so will result in error -214, "Trigger deadlock".

Multiple bursts of a measurement process involving both pre-arm and post-arm readings (ARM:STARt:COUNt > 1 and SENSe:SWEep:OFFSet:POINts < 0) is a special case which causes memory partitioning to occur. This partitioning of memory is handled automatically by the instrument, and is a function of ARM:STARt:COUNt and TRIGger:STARt:COUNt (SENSe:SWEep:POINts). TRIGger:STARt:COUNt is satisfied first, and then ARM:STARt:COUNt is attempted.
