Agilent / Keysight N5221A 13.5 GHz PNA Microwave Network Analyzer

The Keysight N5221A is a 13.5 GHz PNA microwave network analyzer delivering precision S-parameter measurements across 10 MHz to 13.5 GHz. Available in 2-port and 4-port configurations, it combines 127 dB system dynamic range with trace noise as low as 0.002 dB rms at 1 kHz bandwidth, enabling accurate characterization of active and passive microwave devices. The instrument achieves measurement speeds from 4.5 to 26 µsec/point, with full-span sweeps completing in 6.3 ms at 201 points. Maximum output power reaches +13 dBm at the test port, supported by a noise floor of -114 dBm at 10 Hz IF bandwidth and receiver compression at +12 dBm input power. The analyzer maintains temperature stability of 0.05 dB/°C and supports 200 channels with up to 100,001 points per channel and unlimited traces. A 10.4″ LCD touch screen provides intuitive control, while 3.5 mm connectors, USB, LAN, and GPIB interfaces enable flexible integration into test systems.
