With frequency ranges of 9 kHz to 4.5 GHz, 9 kHz to 8.5 GHz, 100 kHz to 20 GHz and 100 kHz to 40 GHz, the 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.

RF Performance
(Designed to meet the highest Standards)
| Then ZNB receivers combine high-power handling capacity with high sensitivity and low trace noise.
The ZNB base unit provides typically 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 drift of typically less than 0.01dB°c and 0.15°/°c.
A calibrated ZNB allows precise measurements over several days without re-calibration.

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. |
High Throughput in Production
(Fast measurements and easy control of external components)
| The ZNB features very short measurement times due to fast synthesizer settling times.
Large IF bandwidths enable fast sampling times.
It also provides high-speed data processing up 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 handlers can easily be controlled thanks to integrated control interfaces like RFFE GPIO, GPIB or 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, allowing all S-parameters of a multiport DUT to be determined.
Automatic calibration units with up to 24 ports enable quick and accurate setup calibration.
