Is that per channel or on all channels? The instrument is equipped with 16 analog to digital (A/D) converters, each with a maximum sampling rate of 250 kHz. Each of the 4 voltage input is sampled at 1024 samples per cycle (Elspec G4430) or every 16/19.5 microseconds (60/50 Hz) on two scales, 800V for constant low voltage monitoring, and 8000V to catch transients. 4 current inputs are sampled at 256 samples per cycle in all three models. The 2 additional current inputs are currently reserved for future use. The 3 temperature inputs are sampled once every cycle.
