The Keysight N5264A PNA-X Measurement Receiver is a high-performance instrument for demanding antenna characterization and RF device testing. Operating from 10 MHz to 10.5 GHz, this five-channel measurement receiver delivers simultaneous data acquisition at up to 400,000 points per second per channel in fast CW mode. The instrument achieves a noise floor as low as −145 dBm with exceptional dynamic range of 134 dB (at 0.1 dB compression), enabling precise gain, radiation pattern, and impedance measurements. Its 4 billion byte data buffer supports single-cut acquisitions up to 500 million points. The N5264A integrates with PNA-X Network Analyzer series systems and accepts external IF signals via SMA connectors for remote mixer and frequency converter applications. With IF bandwidth adjustable from 1 Hz to 5 MHz, measurement accuracy reaches 0.013 dB under specified reference conditions. Ethernet, USB, and GPIB interfaces enable seamless host computer control and trigger synchronization.
