SpecificationsMeasurement RatesTable 1-1 illustrates typical maximum measurement rates for different measurement collection modes.The rate of measurement depends on several factors including the controller speed and the number ofaverages. The Fast Buffered Mode speed does not include bus communication time. Measurement speedincreases significantly using the 8650A Fast Buffered Mode. Storing data in the power meter’s memoryfor later downloading to your controller reduces GPIB protocol overhead. Up to 5000 readings can bebuffered.Table 1-1: Measurement RatesMeasurementCollection ModeReadings per Second(CW Measurement)Readings per Second(MAP, PAP, BAPMeasurement)Normal (TR3), Continuous SingleReadings>300 150Swift Mode, Continuous orBuffered, Bus/TTL triggered >1750 800Fast Buffered Mode, Buffered Data, TimeInterval = 0Fast Modulated Mode, Continuous SingleReadings26,000 N/AN/A 800Individual data points are read immediately after measurement in the Normal mode.
