  • Page 38: Connecting Analog Input Signals

    Chapter 4 Connecting Signals Connecting Analog Input Signals The NI PCI-6110/6111 channels are configured as pseudodifferential inputs. The input signal of each channel, ACH<0..3>+, is tied to the positive input of the PGIA, and each reference signal ACH<0..3>–, is tied to the negative input of the PGIA.

  • Page 39: Types Of Signal Sources

    The PGIA applies gain and common-mode voltage rejection and presents high input impedance to the AI signals connected to the NI PCI-6110/6111. Signals are routed to the positive and negative inputs of the PGIA. The PGIA converts two input signals to a signal that is the difference between the two input signals multiplied by the gain setting of the amplifier.

  • Page 40: Differential Measurements

    See text for information on bias resistors. Differential Connection Considerations A differential connection is one in which the NI PCI-6110/6111 AI signal has its own reference signal or signal return path. The device channels are always configured in DIFF input mode. The input signal is tied to the positive input of the PGIA, and its reference signal, or return, is tied to the negative input of the PGIA.

  • Page 42: Differential Connections For Nonreferenced Or Floating Signal Sources

    Common-Mode Signal Rejection Considerations Figure 4-4 shows connections for signal sources that are already referenced to some ground point with respect to the NI PCI-6110/6111. In theory, the PGIA can reject any voltage caused by ground-potential differences between the signal source and the device. In addition, with pseudodifferential input connections, the PGIA can reject common-mode noise pickup in the leads connecting the signal sources to the device.

  • Page 43: Working Voltage Range

    Like any amplifier, the common-mode rejection ratio (CMRR) of the PGIA is limited at high frequency. This limitation has been compensated for in the design of the NI PCI-6110/6111 by using a common-mode choke on each channel. The purpose of the 10 nF capacitance on the ACH<0..3>–...

    Field Wiring Considerations Environmental noise can seriously affect the measurement accuracy of the NI PCI-6110/6111 if you do not take proper care when running signal wires between signal sources and the device. The following recommendations apply mainly to AI signal routing to the device, although they also apply to signal routing in general.

  • Page 69: Calibration

    Calibration refers to the process of minimizing measurement and output voltage errors by making small circuit adjustments. On the NI PCI-6110/6111, these adjustments take the form of writing values to onboard calibration DACs (CalDACs). Most applications require some form of device calibration. If you do not calibrate the device, the signals and measurements could have very large offset, gain, and linearity errors.

  • Page 70: Self-Calibration

    It is better to self-calibrate when the device is installed in the environment in which it is used. Self-Calibration The NI PCI-6110/6111 can measure and correct for almost all of its calibration-related errors without any external signal connections. NI-DAQ provides a self-calibration method. This self-calibration process, which generally takes less than a minute, is the preferred method of assuring accuracy in your application.

    Sampling rate is the fastest you can acquire data on the device and still achieve accurate results. The NI PCI-6110/6111 has a sampling rate of 5 MS/s. This sampling rate is at 5 MS/s regardless if 1 or 4 channels are acquiring data.
  • Page 87 The NI-DAQ User Manual for PC Compatibles describes the general programming flow and provides example code for using the NI-DAQ API. For a list of functions that support the NI PCI-6110/6111, you can refer to the NI-DAQ Function Reference Help (for NI-DAQ version 6.7 or later) or the NI-DAQ Function Reference Manual (for NI-DAQ version 6.6 or...
  • Page 88 Analog Input and Output Why is there a minimum sampling rate on the NI PCI-6110/6111? The NI PCI-6110/6111 makes use of a pipelined ADC in order to achieve its high sampling rates. Sampling at rates below 20 kS/s can result in improper digitalization, which would appear as noise in the acquired data.

  • Page 90 If you are using NI-DAQ with LabVIEW, some applications that were built using the CTR VIs still run. However, there are many differences between the counters of the NI PCI-6110/6111 and those of other devices: the counter numbers are different, timebase selections are different, and the DAQ-STC counters are 24-bit counters (unlike the 16-bit counters on devices without the DAQ-STC).
