57, Chapter 3: Architecture 4 7 Auto-regeneration Waveform (circular waveform) Auto-regeneration waveform mode can be used to create fixed length waveforms (2048 samples maximum) without any host PC intervention after initialization of the subsystem. An application writes d…

54, Chapter 3: Architecture 44 The following calculations should be performed to convert the raw, stored hexadecimal data to scaled (Voltage) data: 1. Determine the value of a single bit (“bit weight”) in Volts depending on the input range. 12-bit PowerDAQ (span)/40…

25, United Electronic Industries PD2-MF Chapter 2: Installation and Configuration 1 5 Figure 3: Single-ended Inputs Note Unused channels should be shorted to ground using a 1- to 10-KΩ resistor. Differential Inputs: Differential inputs allow up to 32 channels. Each differential channel uses two analog channels — one a…
