Specifications
Real Time Math using hardware
16 (select analog waveform storage or Real Time Math result storage)
Analog channel 1 to channel 16 (multi-channel modules can also be selected as math
sources)
16 bits (2400 LSB/div). Results are converted to 16-bit values according to the scaling
setting and stored in memory.
Math can be performed independently on each channel. Math can be performed on up
to 16 channels at the same time.
Max. math rate (sample rate): 1 MS/s. The math rate is selected automatically
depending on the set frequency. The possible rates are 1 MS/s, 100 kS/s, 10 kS/s,
1 kS/s and 100 S/s.
