TRIGger[:STARt]:COUNt

[: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.
