[:STARt]:COUNt
TRIGger[:STARt]:COUNt <number> specifies the total number of readings
which will be taken during each ARM:STARt:COUNt cycle of a measurement. This
command is identical to (and coupled to) SENSe:SWEep:POINts; setting either will
set both to the same count.

MINimum selects 1 reading.
Memory, post-arm readings only: MAXimum = 524,288 / ARM:STARt:COUNt
Memory battery enabled: MAXimum = (524,288 / ARM:STARt:COUNt) - 4
A/D converter to VME (VXI data transfer) bus: MAXimum = 16,777,215
A/D converter to Local bus: MAXimum = 16,777,215

NOTE: If the non-volatile mode of memory is enabled
(MEMory:BATTery:STATe ON), then all of the maximum reading counts
shown above decrease by four. These four memory locations in each
segment hold the data necessary to recover all readings after a power
failure.
