CHAPTER 4 2 Operation This chapter describes the following features of the PCIE-1744 card: • Analog input ranges and gains • Analog input acquisition modes • A/D sample clock sources • Trigger sources • Analog Input Data Format
Chapter 4 Operation 4.1 Analog Input Ranges and Gains Each channel on the PCIE-1744 can measure bipolar analog input signals ranging within ± 5 V FSR, and can be set up with different input ranges respectively. The sampling rate can be up to 30 MS/s. The PCIE-1744 also provides various gain levels that are programmable on each channel. Table 4-1 lists the effective ranges supported by the PCIE-1744 using these gains. Table 4.1: Gains and Analog Input Range Gain Code 1 2 5 10 Input Range ±5 ± 2.
4.2.2 Pacer Acquisition Mode Use pacer acquisition mode to acquire data if you want to accurately control the time interval between conversions of individual channels in a scan. A/D conversion clock comes from A/D counter or external clock source on connector. A/D conversion starts when the first clock signal comes in, and will not stop if the clock is still continuously sending into it. Conversion data is put into the A/D FIFO.
4.2.4 Delay Trigger Acquisition Mode In delay trigger mode, data acquisition will be activated after a preset delay number of sample has been taken after the trigger event. The delay number of sample ranges from 2 to 65535 as defined in DMA counter. Delay-trigger acquisition starts when the PCIE-1744 detects the trigger event and stop when the specified number of A/D samples has been acquired or when you stop the operation. This triggering mode must work with the DMA data transfer mode enabled.
4.2.5 About Trigger Acquisition Mode Use about-trigger acquisition mode when you want to acquire data both before and after a specific trigger event occurs. This operation is equivalent to doing both a pre-trigger and a post-trigger acquisition. When using software, please specify the following parameters after About-Trigger Acquisition Mode has been set.
4.2.6 Pre-Trigger Acquisition Mode Pre-Trigger mode is a particular application of about-trigger mode. Use pre-trigger acquisition mode when you want to acquire data before a specific trigger event occurs. Pre-trigger acquisition starts when you start the operation and stops when the trigger event happens. Then the specific number of samples will be reversed in the FIFO before the pre-trigger event occurred. Please specify the following parameters, after Pre-trigger Acquisition Mode: has been set.
4.3.1 Internal A/D Sample Clock The internal A/D sample clock uses a 60 MHz time base. Conversions start on the rising edge of the counter output. You can use software to specify the clock source as internal and the sampling frequency to pace the operation. The minimum frequency is 234375 S/s, the maximum frequency is 30 MS/s. According to the sampling theory (Nyquist Theorem), you must specify a frequency that is at least twice as high as the input’s highest frequency component to achieve valid sampling.
4.4 Trigger Sources The PCIE-1744 supports the following trigger sources for post-, delay-, about- and pre-trigger acquisition modes: • Software trigger • External digital (TTL) trigger • Analog threshold trigger. You can define the type of trigger source as rising-edge or falling-edge. These following sections describe these trigger sources in more detail. 4.4.
4.4.3 Analog Threshold Trigger For analog input operations, an analog trigger event occurs when the PCIE-1744 detects a transition from above a threshold level to below a threshold level (falling edge), or a transition from below a threshold level to above a threshold level (rising edge). You should connect the analog signals from the external device to one of the four BNC source connectors.

CHAPTER 5 2 Calibration This chapter offers you a brief guide to the calibration procedure.
Chapter 5 Calibration The PCIE-1744 has been calibrated at the factory for initial use. You are not required to calibrate the PCIE-1744 in normal conditions. However, if calibration is required, the procedure shown in the next pages will show how it is done. To perform an effective calibration, prepare a standard 4-1/2 digits resolution, stable and low-noise DC voltage source. It is important as the accuracy of the device will depend on the accuracy of the DC source. 5.
Step 2:Select the input range of the channel which you want to calibrate. Step 3:Click the Calibration button to start the calibration process. The Calibration Wizard window will pop up. Note: Each calibration process can calibrate only one channel and one input range at a time. Figure 5.2: Click the Calibration Button to Launch the Calibration Step 4:Follow the instruction of Calibration Wizard to input a correct DC voltage as a reference and click the Next button to proceed to the next step. Figure 5.
Step 5:Click the Start button to start the Offset Calibration. Note that the Status will indicate Unknown as default at the beginning. Figure 5.4: The Adjustment Process of Offset Calibration Step 6:If the reference DC voltage source and the wiring are both correct, the calibration will proceed automatically after the Start button is clicked. When the offset calibration is completed, the Status will indicate Succeeded, then click the Next button to proceed to the next step Figure 5.
Step 6a:Once the Status indicates Failed, please check if both the wiring and the input voltage are correct. When finished checking, click the Start button again to restart the procedure, or click the Cancel button to stop the calibration. Figure 5.6: Offset Calibration Failed Step 7:If the offset calibration is completed, it will proceed to the Gain Calibration. The steps of gain calibration are quite similar to those of the offset calibration.
Step 8:Click the Start button to start gain calibration. Note that the Status will indicate Unknown as default at the beginning. Figure 5.8: The Adjustment Process of Gain Calibration Step 9:When the gain calibration is completed click the Next button to proceed. Figure 5.
Step 9a:Once the Status indicates Failed, please check if both the wiring and the input voltage are correct. When finished checking, click the Start button again to restart the procedure, or click the Cancel button to stop the calibration. Figure 5.10: Gain Calibration Failed Step 10:When the current channel is calibrated, click the Finish button to end the procedure.
