ZNB4 Vector Network Analyzer, 2 Port, 4.5 GHz, N

The R&S ZNB vector network analyzers feature a wide dynamic range of up to 140 dB (at 10 Hz IF bandwidth), low trace noise of less than 0.004 dB RMS (at 10 kHz IF bandwidth) and high output power of up to +13 dBm, which can be adjusted electronically in a range of more than 95 dB.

The new analyzers combine high measurement accuracy with exceptional speed- better than 10 s per point. They feature excellent temperature and long-term stability, which ensures reliable measurements over several days without having to recalibrate the units.

These short-depth, compact two-port and four-port analyzers leave plenty of space on the workbench for the measurement application. They feature low operating noise thanks to low power consumption and a sophisticated cooling concept. The low power consumption also reduces operating costs and protects the environment.
