Overview

Product overview

Key product information and technical features.

The PXI-5651 supplies continuous-wave RF signals and onboard modulation for automated test systems. Its direct digital synthesis architecture supports high-resolution frequency hopping and phase-continuous sweeping for fixture and device characterization.

Output amplitude capability varies with frequency. Use the frequency-dependent amplitude tables and settling-time conditions in the official specifications when planning test levels or frequency changes.

  • Continuous-wave RF generation across a 500 kHz to 3.3 GHz range.
  • Onboard FM, binary frequency-shift keying and on-off keying.
  • FM waveform choices include sine, triangle and square.
  • External 10 MHz reference input for frequency referencing.
