Agilent / Keysight N5239A PNA-L Microwave Network Analyzer, 8.5 GHz

The Keysight N5239A PNA-L is a 2-port and 4-port microwave network analyzer covering 300 kHz to 8.5 GHz. Purpose-built for S-parameter characterization of RF and microwave components, it delivers 133 dB dynamic range and supports up to 100,001 measurement points across 200 independent channels. The instrument combines high output power (+13 dBm) with low noise floor (-120 dBm at 10 Hz IF bandwidth) for demanding measurement environments.
