10. Differential channels are useful when you want to measure low level signals when noise is a significant part of the signal or when common mode voltage exists The BNC connection box is shipped in either a differential or single ended channel configuration For the STP and OEM versions of the module you configure the channel type as single ended or differential through software Note For pseudo differential inputs specify single ended in software in this case how you wire these signals determines the configuration Using the Open Layers Control Panel applet you can also select whether to use 10 kQ termination resistance between the low side of each differential channel and isolated analog ground This feature is particularly useful with floating signal sources Refer to page 51 for more information about wiring to inputs and configuring the driver to use bias return termination resistance Principles of Operation The DT9834 Series modules can acquire data from a single analog input channel or from a group of analog input channels The following subsections describe how to specify the channels Specifying a Single Analog Input Channel The simplest way to acquire data from a single analog input channel is to specify the channel for a single value analog input operation using software refer to page 84 for more information about single value operations You can also specify a single channel using the analog input channel li
11. The application displays the values acquired from each channel in a unique color on the oscilloscope view Click Stop from the Toolbar to stop the operation Verifying the Operation of a Module Testing Single Value Digital Input To verify that the module can read a single digital input value do the following 1 Connect a digital input to digital input line 0 on the DT9834 Series module Refer to page 56 for an example of how to connect a digital input 2 Inthe Quick DataAcq application choose Digital Input from the Acquisition menu 3 Select the appropriate DT9834 Series module from the Board list box 4 Click Get The application displays the entire 16 bit digital input value 0 to FFFF in both the Data box and the Digital Input box In addition the application shows the state of the lower eight digital input lines lines 0 to 7 in the graphical display If an indicator light is lit red the line is high if an indicator light is not lit black the line is low Note Although the DT9834 Series modules contain 16 digital input lines the Quick DataAcq application shows indicator lights for the lower eight digital input lines only The 16 bit value is the correct value for all 16 lines 69 Chapter 4 70 Testing Single Value Digital Output Note Although the DT9834 Series modules contain 16 digital output lines the Quick DataAcq application allows you to perform a digital output operation on the l
12. The maximum rate at which the module can read the analog input channels depends on the total number of analog input channels and or counter timer channels see page 80 in the list and whether or not you are reading the digital input port see the next section For example since the maximum throughput of the analog input subsystem is 500 kSamples s the module can read two analog input channels at a rate of 250 kSamples s each or four analog input channels at a rate of 125 kSamples s each 79 Chapter 5 Specifying the Digital Input Port in the Analog Input Channel List The DT9834 Series modules allow you to read the digital input port all 16 digital input lines using the analog input channel list This feature is particularly useful when you want to correlate the timing of analog and digital events To read the digital input port specify channel 16 or channel 32 in the analog input channel list Use channel 16 for modules with 16 single ended channels or eight differential channels use channel 32 for modules with 32 single ended channels or 16 differential channels You can enter channel 16 or 32 anywhere in the list and you can enter it more than once if desired The digital input port is treated like any other channel in the analog input channel list therefore all the clocking triggering and conversion modes supported for analog input channels are supported for the digital input port if you specify them this way Maximu

14. the module finishes outputting the specified number of samples and then stops all subsequent triggers are ignored In an abrupt stop the module stops outputting samples immediately all subsequent triggers are ignored Waveform Generation Use waveform generation mode if you want to output a waveform repetitively The waveform pattern can range from 2 to 120K 122 880 samples if you specify one output channel 2 to 60K 61 440 samples for two output channels 2 to 40K 40 960 samples for three output channels 2 to 30K 30 720 samples for four output channels or 2 to 24K 24 576 samples for five output channels Note The waveform pattern size must be the same for all output channels and the total number of samples must be a multiple of the total number of output channels Use software to fill the output buffer with the values that you want to write to the channels in the output channel list For example if your output channel list contains only DACO and the digital output port specify the values in the output buffer as follows the first output value for DACO the first output value for the digital output port the second output value for DACO the second output value for the digital output port and so on When it detects a trigger the host computer transfers the entire waveform pattern to the module and the module starts writing output values to the output channels as determined by the output channel list Use software to
