What it is
The N5230A is available as a 2-port or 4-port PNA-L microwave network analyzer. The instrument covers frequencies from 300 kHz to up to 50 GHz depending on the configuration. The N5230A offers a high dynamic range of 127 dB at 20 GHz at the test port. The analyzer features low trace noise of 0.002 dB rms at 1 kHz bandwidth. The N5230A provides fast measurement speed of 4.5 to 26 µsec per point. The analyzer has high stability of 0.05 dB per degree Celsius. The N5230A supports 32 measurement channels, unlimited traces, and up to 16,001 points per channel. The instrument has connectivity with an open Windows XP operating system, six USB connectors, LAN, and GPIB.[1][2][4][3]
How it works
The N5230A supports state-of-the-art calibration capabilities and a wide range of electronic calibration (ECal) modules. The analyzer can perform single-ended and balanced measurements. The N5230A offers advanced applications for mixer and pulse measurements.[1]
