  • Page 25 your data acquisition device. The multiplexed mode is the default and recommended mode to use with SCXI. In the parallel mode, each SCXI module is directly connected to one data acquisition device and each analog input channel on a SCXI module is connected to a separate analog input channel on the data acquisition device.
  • Page 26 ‘z’ in the SCXI channel string represents the actual channel number (e.g. 3). Channels on the SCXI modules are numbered starting at zero. You specify a range of channels on your SCXI modules by listing the first and last channel separated with a colon (e.g. 0:5). You only use the SCXI channel string when the SCXI is operating in multiplexed mode and channels are multiplexed onto one or more channels of the data acquisition device.
  • Page 27 Table 3-1 lists other possible combinations for SCXI channel strings. String Syntax ob0!sc1!md2!5 ob0!sc1!md2!0:7 ob0!sc1!md4!5:12 ob0!sc1!md3!3:4 ob1!sc2!md1!20:24 In the parallel mode, each analog input SCXI module is connected directly to a DAQ device and you must specify the channels of your DAQ device in the channel list, not the SCXI channel string.
  • Page 28 The current version of Measure does not support the use of analog output (AO) channels on the SCXI-1124 module. You can use the analog output channels of the SCXI-1200 module by selecting the device number and the AO channel number as you would with any other DAQ device.
  • Page 29 This chapter introduces some basic concepts of data acquisition and contains a reference for analog input configuration, hardware digital triggering, analog input modes, and advanced timing. You should be familiar with the hardware capabilities of your data acquisition device. Measure works with a wide variety of National Instrument DAQ devices.

  • Page 32 Enter the lower voltage limit for the channels in the channel string. This voltage is the minimum voltage that is measured at any of the analog input channels that are specified in the channel string. You may add more than one channel string to your scan list and each channel string may have a different set of high and low limits.
  • Page 33 in time the channels are sampled within each scan. The reciprocal of the channel clock rate is called the interchannel delay, or channel interval, shown in Figure 4-2. channel interval Figure 4-2 Measure automatically calculates the smallest, safe interchannel delay for your given configuration and device.

Choices for Analog Input Mode Differential Channels Referenced Single-Ended Channels Non-Referenced Single-Ended Channels Note: The Analog Input Mode on some devices is not configurable within Measure. If you have such a device, you must exit Measure and change the mode using the NI-DAQ Configuration Utility.
  • Page 38 Most of the time, you do not have to configure the advanced timing settings because Measure automatically selects reasonable values for you. In some cases, however, you might want to select an interchannel delay or even use an external channel clock. You can configure these settings through the Advanced Timing Settings dialog box, shown in Figure 4-6.
  • Page 39 This chapter introduces some concepts of data acquisition and contains a reference for basic and advanced Analog Output Configuration. You should be familiar with the hardware capabilities of your data acquisition device. To configure an analog output task, first you must select the channels on which you want to generate your signals.
  • Page 40 Option Channel Specify the analog output channel on which to generate a signal. You may only specify one channel at a time. Data cells Specify the source range of the voltage values to write to the digital-to- analog converter (DAC) for the channel. Either explicitly type the cell address, or highlight the text in this field and then select a row of cells or a column of cells on any worksheet in the workbook.
  • Page 41 Note: If you want to generate waveforms on more than one channel, each channel must be added separately to the channel list. Also, Measure requires that all channels have the same number of voltage values to generate. If the range of data for one channel is larger than for another channel in the scan list, the shorter range of data is padded with the value 0 when Measure generates the waveforms.
  • Page 42 Option Description High Limit (volts) The high limit is equal to your reference voltage and is the maximum voltage the DAC can produce. If you have an AT-AO-6/10 board and your Channel Type is current, you can calculate the maximum possible current with the following equation.
  • Page 43 This chapter describes how to run tasks from within Visual Basic for Applications. There are two ways to execute DAQ Add-In functions in a VBA module. Indirectly, you can use Application.Run returnValue=Application.Run(“FuncName”, arg1) Application.Run “FuncName”, arg1 Directly, after you add a reference to the DAQ Add-In. To add a reference to the DAQ Add-In, select Tools»References and select the checkbox next to the Data Acquisition Add-In.
  • Page 44 Option TaskName The name of a task in the active workbook. NewTargetRange The address of a range on a worksheet that receives the acquired data. If you fail to specify a worksheet explicitly in the address of this macro, Measure assumes that the range is on the active worksheet. If no worksheet is active, Measure returns an error.

  • Page 85 Prefix Meaning µ- ADC resolution Value pico- nano- micro- milli- kilo- mega- One-dimensional. Two-dimensional. Analog-to-digital. Analog-to-digital converter. An electronic device, often an integrated circuit, that converts an analog voltage to a digital number. The resolution of the ADC, which is measured in bits. An ADC with 16 bits has a higher resolution, and thus a higher degree of accuracy than a 12-bit ADC.
  • Page 86 Analog Input Configuration Analog Output Configuration analog trigger array Asynchronous bipolar buffer Byte The specification of the analog input channels, input limits, input mode, and scan rate that Measure will use to acquire a waveform. The specification of the analog output channels, output limits, data points, and update rate that Measure will use to generate a waveform.
