  • Page 3 NI-9232 Getting Started NI-9232 Getting Started NI-9232 Overview In this article, the NI-9232 with screw terminal and NI-9232 with BNC are referred to inclusively as the NI-9232. The information in this document applies to all versions of the NI-9232 unless otherwise specified.
  • Page 4 The small amount of variation in gain with respect to frequency is called the passband flatness. The digital filters of the NI-9232 adjust the frequency range of the passband to match the data rate. Therefore, the amount of gain or attenuation at a given frequency depends on the data rate.

  • Page 5: Alias-Free Bandwidth

    NI-9232 Getting Started Alias-Free Bandwidth Any signal that appears in the alias-free bandwidth of the NI-9232 is not an aliased artifact of signals at a higher frequency. The alias-free bandwidth is defined by the ability of the filter to reject frequencies above the stopband frequency, and it is equal to the data rate minus the stopband frequency.
  • Page 6 NI-9232 Getting Started Data Rates with the Internal Master Timebase The following table lists the available data rates with the internal master timebase. Table 1. Available Data Rates with the Internal Master Timebase (kS/s) Decimation Rate Clock Divider 102.40 51.20 34.13...
  • Page 7 0.98 External Master Timebase The NI-9232 also can accept an external master timebase or export its own master timebase. To synchronize the data rate of an NI-9232 with other modules that use master timebases to control sampling, all of the modules must share a single master timebase source.

  • Page 8: Connecting Signal Sources

    NI-9232 Getting Started 13.1072 MHz, the NI-9232 has a different set of data rates. Refer to the software help for information about configuring the master timebase source for the NI-9232. Connecting the NI-9232 The NI-9232 provides connections to three simultaneously sampled analog input channels.
  • Page 9 NI-9232 Getting Started If you make a ground-referenced connection between the signal source and the NI-9232, make sure the voltage on the AI+ and the AI- connections are in the channel-to-earth safety voltage range to ensure proper operation of the NI-9232.

  • Page 10: Wiring For High-Vibration Applications

    Negative analog input signal connection Wiring for High-Vibration Applications If your application is subject to high vibration, NI recommends that you follow these guidelines to protect connections to the NI-9232 with screw terminal: Use ferrules to terminate wires to the detachable connector.
