Using SCXI with Measure DAQ This chapter describes how to use the Measure data acquisition (DAQ) Add-in in Excel with your Signal Conditioning Extension for Instrumentation (SCXI) equipment. SCXI is a set of modules and terminal blocks used as a signal condition front-end for your data acquisition devices. These modules perform tasks such as multiplexing large numbers of signals, amplifying lowlevel signals, providing isolation between your data acquisition devices and transducers, and so on.
Chapter 3 Using SCXI with Measure DAQ 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. Not all data acquisition devices or SCXI modules support the parallel mode. Consult your data acquisition hardware user manual for more information.
Chapter 3 Using SCXI with Measure DAQ ‘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.
Chapter 3 Using SCXI with Measure DAQ Figure 3-1. Selecting the Add>> button Table 3-1 lists other possible combinations for SCXI channel strings. Table 3-1. SCXI Channel Strings Syntax String Syntax Description ob0!sc1!md2!5 Channel 5 on module 2 of SCXI chassis 1 is read through onboard channel 0. ob0!sc1!md2!0:7 ob0!sc1!md4!5:12 Channels 0-7 on module 2 and channels 5-12 on module 4 of chassis 1 are read through onboard channel 0.
Chapter 3 Using SCXI with Measure DAQ SCXI Analog Output 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.
Analog Input Reference 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. DAQ Device Overview Measure works with a wide variety of National Instrument DAQ devices. This chapter provides a technical overview and reference information about using Measure for analog input operations.
Chapter 4 Analog Input Reference Analog Input Configuration Overview Select DAQ»Configure DAQ Tasks and then press the AI button to open the Analog Input Configuration dialog box, shown in Figure 4-1. The sections below describe the fields within the Analog Input Configuration dialog box, and Table 4-2 explains the remaining options at the bottom of the Analog Input Configuration dialog box. Figure 4-1.
Chapter 4 Analog Input Reference left-to-right is the order that Measure scans the channels. The following is a table of valid channel strings. Table 4-1.
Chapter 4 Analog Input Reference Low Limit 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. When you create an AI task, Measure enters the default value for your device.
Chapter 4 Analog Input Reference 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. 0 1 2 3 0 1 2 3 0 1 2 3 scan interval channel interval Figure 4-2. Scan Clock and Channel Clock Measure automatically calculates the smallest, safe interchannel delay for your given configuration and device.
Chapter 4 Analog Input Reference Display When determining where to display the acquired data, Measure uses three pieces of information you specify.
Chapter 4 Mode Description OK Cancel Analog Input Reference Change the analog input mode from the setting that you specify when you run the NI-DAQ Configuration Utility, WDAQCONF.EXE. Measure automatically selects the option that reflects the current setting for your device. Enter a short description of your task. Measure displays a description of a task below the task list in the DAQ Tasks dialog box.
Chapter 4 Analog Input Reference Table 4-3. Choices for Hardware Digital Trigger Choices for Hardware Digital Trigger Description Start acquisition on trigger Select this option if you want to start your acquisition on the rising edge of the PFI0/EXTTRIG/STARTTRIG (depending on the board you are using) input on the connector. Otherwise, Measure starts the acquisition with a software trigger.
Chapter 4 Analog Input Reference Table 4-4 contains a list Analog Input Mode choices with descriptions of their use. Table 4-4. Choices for Analog Input Mode Dialog Box Choices for Analog Input Mode Description Differential Channels Select this option if you want each channel to use two analog channel input lines. One line connects to the positive input of the device amplifier, and the other connects to the negative input of the amplifier.
Chapter 4 Analog Input Reference Advanced Timing Settings 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. Figure 4-6.
Analog Output Reference 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. Analog Output Configuration Overview To configure an analog output task, first you must select the channels on which you want to generate your signals. Refer to Table 5-1 for detailed information. Figure 5-1.
Chapter 5 Analog Output Reference Table 5-1. Analog Output Configuration Reference Option Description 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-toanalog converter (DAC) for the channel.
Chapter 5 Note: Analog Output Reference 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.
Chapter 5 Analog Output Reference Table 5-2. Advanced Analog Output Configuration Options 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. Imax = Vref + 2.5/0.625 mA The following list contains the default settings for high limit.
Using Measure Data Acquisition Tasks with VBA 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. 1. Indirectly, you can use Application.Run returnValue=Application.Run(“FuncName”, arg1) Application.Run “FuncName”, arg1 2. 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.
Chapter 6 Using Measure Data Acquisition Tasks with VBA Parameters Option Description 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.
Chapter 6 Using Measure Data Acquisition Tasks with VBA GetDAQErrorMessage Finds and returns a description of an error code returned by the DAQ function. Syntax Function GetDAQErrorMessage(ErrorCode As Integer) As String Parameters Option ErrorCode Description A non-zero number returned by the DAQ function that indicates an error. Return Value A short description of the error code. Example See the previous example for the DAQ function.

Title: Measure® Data Acquisition User Manual Edition Date: August 1996 Part Number: 321004B-01 Please comment on the completeness, clarity, and organization of the manual.
Prefix Meaning Value pnµmkM- piconanomicromillikilomega- 10-12 10-9 10-6 10-3 103 106 Numbers/Symbols 1D One-dimensional. 2D Two-dimensional. A A/D Analog-to-digital. ADC Analog-to-digital converter. An electronic device, often an integrated circuit, that converts an analog voltage to a digital number. ADC resolution 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. AI Analog input.
Glossary Analog Input Configuration The specification of the analog input channels, input limits, input mode, and scan rate that Measure will use to acquire a waveform. Analog Output Configuration The specification of the analog output channels, output limits, data points, and update rate that Measure will use to generate a waveform. analog trigger A trigger that occurs at a user-selected point on an incoming analog signal.
Glossary C channel Pin or wire lead to which you apply or from which you read the analog or digital signal. Analog signals can be single-ended or differential. For digital signals, you group channels to form ports. Ports usually consist of either four or eight digital channels. channel clock The clock controlling the time interval between individual channel sampling within a scan. Boards with simultaneous sampling do not have this clock.
Glossary DMA Direct memory access. A method by which data you can transfer data to computer memory from a device or memory on the bus (or from computer memory to a device) while the processor does something else. DMA is the fastest method of transferring data to or from computer memory. driver Software that controls a specific hardware device, such as a data acquisition board. E EISA Extended Industry Standard Architecture.
Glossary does not uniquely determine the upper and lower voltage limits. An input range of 10 V could mean an upper limit of +10 V and a lower of 0 V or an upper limit of +5 V and a lower limit of -5 V. The combination of input range, polarity, and gain determines the input limits of an analog input channel. For some boards, jumpers set the input range and polarity, while you can program them for other boards. Most boards have programmable gains.
Glossary output limits The upper and lower voltage or current outputs for an analog output channel. The output limits determine the polarity and voltage reference settings for a board. P PGIA Programmable gain instrumentation amplifier. postriggering The technique you use on a data acquisition board to acquire a programmed number of samples after trigger conditions are met.
Glossary SCXI Signal Conditioning eXtensions for Instrumentation. The National Instruments product line for conditional low-level signals within an external chassis near sensors, so only high-level signals in a noisy environment are sent to data acquisition boards. sec Seconds single-ended inputs Analog inputs that you measure with respect to a common ground. software trigger A programmed event that triggers an event such as data acquisition.
Glossary V V volts. Visual Basic for Applications (VBA) The programming language built into Microsoft Excel. Vref Voltage reference. W waveform Measure Data Acquisition User Manual Multiple voltage readings taken at a specific sampling rate.
