National Instruments PXIe-5651 PXI RF Analog Signal Generator

The National Instruments PXIe-5651 (Part Number: 781216-01) is an Analog Signal Generator with continuous-wave generation capabilities and FM, 2‑FSK, or OOK modulation. This model can generate AM, FM, PM, and pulse wave signals continuously. The NI PXIe-5651 supports a frequency range from 500 kHz to 3.3 GHz, a frequency resolution range from <3 Hz to 6 Hz, a maximum output power of 12 dBm, and a typical tuning time of 1.5 ms.

This module features a reference clock internal accuracy of ±3 ppm, a maximum initial and ±1 ppm, maximum at temperatures ranging from 15 ºC to 35 ºC. The PXIe-5651 Analog Signal Generator has an Internal Reference Output frequency of 10 MHZ, an output impedance of 50 Ω, and an amplitude of 1 Vpk-pk into 50 Ω. This model also has an external Reference Input frequency of 10 MHz ±10 ppm, an input impedance of 50 Ω, and an amplitude of 0.2 Vpk-pk to 1.5 Vpk-pk into 50 Ω. The device has a power requirement of 1 A maximum at both +3.3 V and +12 V.

The NI PXIe-5651 is flexible as it allows users to perform analog and digital modulation through the onboard DDS circuit, which provides frequency modulation and frequency-shift keying for applications, such as bit error rate test, antenna testing, or even keyless entry. The device has a recommended warm-up time of 30 minutes and should be calibrated at least once a year.

The PXIe-5651 is run using the NI-RFSG Instrument driver which can be programmed with software packages/application development environments (ADEs) such as LabVIEW, LabWindows/CVI, or Measurement Studio. The device hardware can be configured using the Measurement & Automation Explorer (MAX) tool.

The random vibration in a non-operating environment is between 5 Hz to 500 Hz, 2.4 grms. The PXIe-5651 is a 3U, one slot, PXI Express module. It weighs 14.6 oz., and measures 8.5 x 0.8 x 5.1 in. in physical dimensions. The NI device has a recommended operating temperature range of 0 °C to 55 °C, and a storage temperature range of -40 °C to 70 °C. It has a non-operating random vibration of 5 Hz to 500 Hz (2.4 grms).

The PXIe-5651 is available to be calibrated. While the recommended calibration period for individual parts varies, most parts should be calibrated either annually or every two years to ensure accuracy. If you need the PXIe-5651 calibrated, Apex Waves provides options. We offer high-quality NIST accredited calibrations through a 3rd party, with an average turnaround time of 1 to 2 weeks. When you order the PXIe-5651 with us, you can request basic (unaccredited) in-house calibration that will calibrate the part to the manufacturer specifications prior to being shipped.
