Chapter 4 Signal Connections National Instruments Corporation 4-31 DAQCard E Series User Manual scan. The sample interval counter is started if you select internally triggered CONVERT*. As an output, the STARTSCAN signal reflects the actual start pulse that initiates a scan.
Chapter 4 Signal Connections DAQCard E Series User Manual 4-32 National Instruments Corporation The CONVERT* pulses are masked off until the DAQCard generates the STARTSCAN signal. If you are using internally generated conversions, the first CONVERT* will appear when the onboard sample interval counter reaches zero.
Chapter 4 Signal Connections National Instruments Corporation 4-33 DAQCard E Series User Manual Scans generated by either an internal or external STARTSCAN signal are inhibited unless they occur within a data acquisition sequence.
Chapter 4 Signal Connections DAQCard E Series User Manual 4-34 National Instruments Corporation The ADC switches to hold mode within 60 ns of the selected edge. This hold-mode delay time is a function of temperature and does not vary from one conversion to the next.
Chapter 4 Signal Connections National Instruments Corporation 4-35 DAQCard E Series User Manual mode, the first active edge disables the STARTSCAN signal, and the second active edge enables STARTSCAN.
Chapter 4 Signal Connections DAQCard E Series User Manual 4-36 National Instruments Corporation UISOURCE Signal Any PFI pin can externally input the UISOURCE signal, which is not available as an output on the I/O connector. The UI counter uses the UISOURCE signal as a clock to time the generation of the UPDATE* signal.
Chapter 4 Signal Connections National Instruments Corporation 4-37 DAQCard E Series User Manual General-Purpose Timing Signal Connections The general-purpose timing signals are GPCTR0_SOURCE, GPCTR0_GATE, GPCTR0_OUT, GPCTR0_UP_DOWN, GPCTR1_SOURCE, GPCTR1_GATE, GPCTR1_OUT, GPCTR1_UP_DOWN, and FREQ_OUT.
Chapter 4 Signal Connections DAQCard E Series User Manual 4-38 National Instruments Corporation The 20 MHz or 100 kHz timebase normally generates the GPCTR0_SOURCE signal unless you select some external source.
Chapter 4 Signal Connections National Instruments Corporation 4-39 DAQCard E Series User Manual input (High-Z) at startup. Figure 4-26 shows the timing of the GPCTR0_OUT signal.
