With frequency ranges of 9 kHz to 4.5/8.5 GHz and 100 kHz to 20/26.5/40/43.5 GHz, the ZNB network analyzers are targeted at applications in the mobile radio, electronic goods and aerospace and defense sectors, plus they can be used in high-speed printed board design. The ZNB is the right choice when it comes to developing, producing and servicing RF components such as amplifiers, mixers, filters, connectors and cables.
The 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 ZNB analyzers combine high measurement accuracy with exceptional speed – better than 5 µs per point. They feature excellent temperature and long-term stability, which ensures reliable measurements over several days without having to recalibrate the units.

RF Performance
(Designed to meet the highest standards)
| The ZNB receivers combine high-power handling capacity with high sensitivity and low trace noise.
The ZNB base unit typically has a 140dB dynamic range.
The ZNB8-B5x option extends the dynamic range to up to 150dB for measurements between ports.
The analyzer measures S-parameters with very low magnitude and phase drifts typically lower than 0.01 dB/°C and 0.15°/°C.
A calibrated ZNB allows precise measurements over several days without recalibration.

Versatile Options
(Convenient characterization of active and passive RF components)
| The ZNB offers many features and options including embedding/de-embedding features, mixed-mode S-parameters for balanced DUT characterization and redefined S-parameters for flexible test setup configuration.
Time domain measurement options with eye diagrams, frequency-converting measurements and two independent internal generators are also available.
|
High Throughput in Production
(Fast measurements and easy control of external components)
| Fast synthesizer settling times give the ZNB very short measurement periods.
Large IF bandwidths enable fast sampling times.
It also provides high speed data processing to the display and fast LAN or IEC/IEEE data transfer to the controller.
Features such as segmented sweep further improve measurement times.
Modules or external parts can easily be controlled with integrated control interfaces such as RFFE GPIO, GPIB and handler I/O
|
Multiport Measurements
(Measurements on up to 48 ports)
| The ZNB in combination with various switch matrices is a comprehensive solution for complex measurements on modules with up to 48 ports.
The matrices from Rohde & Schwarz deliver full crossbar measurements to determine all S-parameters for a multiport DUT.
Automatic calibration units with up to 24 ports enable quick and accurate setup calibration.
