Description

NI  SCXI-1124  Analog output module

Channel parameters: It is equipped with 6 independently isolated analog-to-digital converter channels, capable of simultaneously processing and outputting multiple signals, meeting the requirements of multi-channel signal output.
Signal output: Each channel can be configured as either voltage or current output. The voltage output can be selected from one of the three unipole or three bipolar ranges. When it comes to current output, each channel can output 0 to 20mA.
Isolation feature: Each channel has an isolation function, which can ensure that the signal is not interfered with during transmission, improve measurement accuracy and stability, and is suitable for occasions with high requirements for signal purity.

Sampling rate correlation: The measurement rate is 600,000S/s per channel, and the sampling rate accuracy is 50ppm. When the sequence length is less than 300 steps, each channel in each cycle can be updated 100,000 times per second. When the sequence length is ≥300 steps, each board is updated 100,000 times per second in each cycle.
Trigger characteristics: The input trigger types include start, source, sequential advancement, measurement, etc. The source is the PXI trigger line from 0 to 7, with configurable polarity and a minimum pulse width of 100 nanoseconds. The output flip-flop types include active completion, sequence iteration completion, etc. The destination is PXI flip-flop 0 to 7, the polarity is configurable, and the pulse width can be configured between 250ns and 1.6μs.

Calibration-related: The module is software-configurable. The on-board EEPROM is used to store calibration constants, facilitating users to configure and calibrate through software.
Power supply requirements: PXI explicitly states that the 12V power supply rail is 2.1A and the 3.3V power supply rail (no specific current requirements are mentioned).
Physical parameters: Dimensions are 3U, single slot, PXI high-speed/CompactPCI fast module, approximately 2.0 cm ×13.0 cm ×21.6 cm, weight 408 grams. The front panel connector is a 25-bit D-SUB male connector.

Working environment: The working temperature range is 0°C to 55°C, and the relative humidity range is 10% to 70% without condensation. For every temperature above 40°C, the relative humidity decreases by 1.3%. The storage temperature range is -40 °C to 70°C, and the relative humidity range is 5% to 95% without condensation. During operation, the shock peak is 30g, semi-sinusoidal, 11ms pulse, the random vibration frequency ranges from 5 Hz to 500 Hz, 0.3grms. The random vibration during non-operation ranges from 5 Hertz to 500 Hertz, and is 2.4grms.
