  • Page 84: Calibration

    This chapter discusses the calibration procedure for the device. Calibration is the process of minimizing measurement and output voltage errors by making small circuit adjustments. On the NI 6052E, these adjustments take the form of writing values to onboard calibration DACs (CalDACs).

  • Page 85: Self-Calibration

    Self-Calibration The device can measure and correct for almost all of its calibration-related errors without any external signal connections. NI software provides a self-calibration method, which generally takes less than a minute and is the preferred method of ensuring accuracy in your application. Initiate self-calibration to minimize the effects of any offset, gain, and linearity drifts, particularly those due to the device not being fully warmed up.

  • Page 101 What is the DAQ-STC? The DAQ-STC is the system timing control application-specific integrated circuit (ASIC) designed by NI and is the backbone of the E Series devices. The DAQ-STC contains seven 24-bit counters and three 16-bit counters. The counters are divided into the following three groups: •...
  • Page 102 What jumpers should I be aware of when configuring the device? The PCI-6052E, PXI-6052E, and DAQPad-6052E are jumperless and switchless. Which NI document should I read first to get started using DAQ software? The DAQ Quick Start Guide and the NI-DAQ documentation or ADE release notes are good places to start.
  • Page 103 The NI-DAQ User Manual for PC Compatibles contains example code and describes the general programming flow when using the NI-DAQ C API. For a list of functions that support the NI 6052E, refer to the NI-DAQ Function Reference Help (NI-DAQ 6.7 or later) or the NI-DAQ Function Reference Manual for PC Compatibles (NI-DAQ 6.6 or earlier).

  • Page 105 For example, can I configure ACH 0 in DIFF input mode and ACH1 in RSE input mode? You can enable channels on the NI 6052E to acquire in different modes, but different pairs of channels are used in different modes. In the example configuration given above, ACH0 and ACH8 are configured in DIFF mode and ACH1 and AIGND are configured in RSE mode.

  • Page 107 Do the counter/timer applications that I previously wrote work with the DAQ-STC? If you are using NI-DAQ with LabVIEW, some of your applications drawn using the CTR VIs do still run. However, there are many differences in the counters between the E Series and other devices. The counter numbers are...
