NI-9222 Specifications
Connector Types
The NI-9222 has more than one connector type: NI-9222 with screw terminal and NI-9222 with BNC. Unless the connector type is specified, NI-9222 refers to both connector types.
Definitions
Warranted specifications describe the performance of a model under stated operating conditions and are covered by the model warranty.
Characteristics describe values that are relevant to the use of the model under stated operating conditions but are not covered by the model warranty.
- Typical specifications describe the performance met by a majority of models.
- Nominal specifications describe an attribute that is based on design, conformance testing, or supplemental testing.
Specifications are Typical unless otherwise noted.
Conditions
The following specifications are typical for the range -40 °C to 70 °C unless otherwise noted. All voltages are relative to the AI- signal on each channel unless otherwise noted.

Safety Voltages
Connect only voltages that are within the following limits:

Measurement Category I
Measurement Category I is for measurements performed on circuits not directly connected to the electrical distribution system referred to as MAINS voltage. MAINS is a hazardous live electrical supply system that powers equipment. This category is for measurements of voltages from specially protected secondary circuits. Such voltage measurements include signal levels, special equipment, limited-energy parts of equipment, circuits powered by regulated low-voltage sources, and electronics.

1 Refer to the Safety Voltages section for more information about safe operating voltages.
2 The minimum measurement voltage range is the largest voltage the NI-9222 is guaranteed to accurately measure.
3 FPGA User-Controlled I/O Sampling provides low level access to sample acquisition and transfer, and higher sample rates. Visit ni.com/info and enter the Info Code samplerate for information about FPGA User-Controlled I/O Sampling.
4 Range equals ±10.6 V.
5 Uncalibrated accuracy refers to the accuracy achieved when acquiring in raw or unscaled modes where the calibration constants stored in the module are not applied to the data.
6 -3 dB bandwidth for input amplitude at 10% of the input range.
