7. Sample reading Scan Sequencer Simultaneous Sample and Hold Single ended mode Trigger TTL Unipolar Differential mode voltage refers to a voltage difference between two signals that are referenced to a common point Example Signal 1 is 5 VDC referenced to common Signal 2 is 6 VDC referenced to common If the 5 VDC signal is used as the reference the differential mode voltage is 1 VDC 6 VDC 5 VDC 1 VDC If the 6 VDC signal is used as the reference the differential mode voltage is 1 VDC 5 VDC 6 VDC 1 VDC Electrostatic discharge ESD is the transfer of an electrostatic charge between bodies having different electrostatic potentials This transfer occurs during direct contact of the bodies or when induced by an electrostatic field ESD energy can damage an integrated circuit IC Some transducers e g strain gages thermistors and resistance temperature detectors RTDs require a known voltage or current Typically the variation of this signal through the transducer corresponds to the condition measured The degree to which an input signal is amplified or attenuated to allow greater accuracy and resolution can be expressed as xn or dB The arrangement or operation of a circuit so that signals from another circuit or device do not affect the isolated circuit In reference to Daq devices isolation usually refers to a separation of the direct link between the signal source and the ana
8. The advantage of this mode is that the digital and counter inputs do not consume an analog input time slot and therefore do not reduce the available bandwidth for making analog input measurements For example presume all 24 bits of digital input are enabled and all four 32 bit counters are enabled and eight channels of analog inputs are in the scan sequence at full lusec channel rate At the beginning of each analog input scan sequence which would be 8 usec in total duration all digital inputs and counter inputs will be measured and sent to the PC during the first usec of the analog scan sequence 1 4 Daq Systems and Device Overviews 988093 DaqBoard 3000 Series User s Manual Another synchronous mode allows digital inputs to be scanned every time an analog input channel 1s scanned For example if eight analog inputs are scanned at 1 usec per channel continuously and 24 bits of digital inputs are enabled then the 24 bits of digital inputs will be scanned at 24 bits per 1 usec If counters are enabled in this mode they will be scanned at once per scan in the same manner as in the first example above Note It is not necessary to read counters as often as it is to read digital inputs This is because counters continue to count pulses regardless of whether or not they are being read by the PC Example 1 Analog channel scanning of voltage inputs The figure below shows a simple acquisition The scan is programmed pre acquisition and is made up o
9. When using a counter for a trigger source it is a good idea to use a pre trigger with a value of at least 1 The reason is that all counters start at zero with the initial scan and there will be no valid reference in regard to rising or falling edge Setting a pre trigger to 1 or more ensures that a valid reference value is present and that the first trigger will be legitimate Introduction Rotary shaft encoders are frequently used with CNC equipment metal working machines packaging equipment elevators valve control systems and in a multitude of other applications in which rotary shafts are involved The encoder mode allows the 3000 Series board to make use of data from optical incremental quadrature encoders When in the encoder mode the board accepts single ended inputs When reading phase A phase B and index Z signals the 3000 Series board provides positioning direction and velocity data J Fi e e e fel The 3000 Series board can only receive input from up to two encoders The 3000 Series board supports quadrature encoders with a 16 bit Counter Low or a 32 bit Counter High counter 20 MHz frequency and x1 x2 and x4 count modes With only phase A and phase B signals 2 channels are supported with phase A phase B and index Z signals 1 channel is supported Quadrature encoders generally have 3 outputs A B and Z The A and B signals are pulse trains driven by an optical sensor inside the encoder As the encoder s

13. Going back to the above example if the setpoint for analog input Channel 2 required a DAC update it would occur 5us after the ADC conversion for Channel 2 or 6us after the start of the scan When using setpoints to control any of the DAC outputs increased latencies may occur if attempting to stream data to DACs or pattern digital output at the same time The increased latency can be as long as the period of the DAC pacer clock For these reasons avoid streaming outputs on any DAC or pattern digital output when using setpoints to control DACs 6 6 Setpoint Configuration for Output Control 908794 DaqBoard 3000 Series User s Manual More Examples of Control Outputs Detection on an Analog Input DAC and P2C Updates Update Mode Update on True and False Criteria Ch 5 example Below Limit Ch 4 example Inside Window In this example Channel 5 has been programmed with reference to one setpoint Limit A defining a low limit and Channel 4 has been programmed with reference to two setpoints Limits A and B which define a window for that channel Channel Condition State of Action Detect Signal Below Limit A True When Channel 5 analog input voltage is below the limit A for Channel 5 update DAC1 with Output Value 0 0V False When the above stated condition is false update DAC1 with the Output Value of minus 1 0V Within Window True When Channel 4 analog input voltage is within the window Between Limit A update P2C with 70h

45. an output can be updated is determined by the following three factors o scan rate o synchronous sampling mode o type of output to be updated Example We set an acquisition to have a scan rate of 100 kHz This means each scan period is 10us Within the scan period we will sample six analog input channels These are shown in the following figure as Channels 1 through 6 The ADC conversion occurs at the beginning of each channel s lus time block lt Start of Scan Start of Scan 3 P2C Example of P2C or DAC Latency If we apply a setpoint on analog input Channel 2 then that setpoint will get evaluated every 10us with respect to the sampled data for Channel 2 Due to the pipelined architecture of the Analog to Digital Converter system the setpoint cannot be evaluated until 2us after the ADC conversion In the example above the P2C digital output port can be updated no sooner than 2us after Channel 2 has been sampled or 3us after the start of the scan This 2us delay is due to the pipelined ADC architecture The setpoint is evaluated 2us after the ADC conversion and then P2C can be updated immediately P2C digital outputs can be updated immediately upon setpoint detection This is not the case for analog outputs as these incur another 3us delay This is due to the shifting of the digital data out to the D A converter which takes lus plus the actual conversion time of the D A converter 1 e another 2us worst case
