Used Rohde & Schwarz ZNB8-4 Vector Network Analyzer, 8.5GHz, 4-Port, Type N(f)

Product Highlights

Vector Network Analyzer 8.5GHz,4-Port,Type N(f)

• Frequency range from 9 kHz up to 40 GHz
• 4 ports
• Wide dynamic range of up to 140 dB
• Short sweep times, e.g. 4 ms for 401 points
• Wide power sweep range of 98 dB

With frequency ranges of 9 kHz to 4.5 GHz/8.5 GHz and 100 kHz to 20 GHz/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 R&S®ZNB is the right choice when it comes to developing, producing and servicing RF components such as amplifiers, mixers, filters, connectors and cables.

RF performance

Designed to meet the highest standards

The R&S®ZNB receivers combine high-power handling capacity with high sensitivity and low trace noise. The R&S®ZNB base unit provides typically 140 dB dynamic range. The R&S®ZNB8-B5x option extends the dynamic range to up to 150 dB for measurements between ports. The analyzer measures S-parameters with very low magnitude and phase drift of typically less than 0.01 dB/°C and 0.15°/°C. A calibrated R&S®ZNB allows precise measurements over several days without recalibration.

Versatile options

Convenient characterization of active and passive RF components

The R&S®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 including eye diagrams and frequency-converting measurements with two independent internal generators are also available.

High throughput in production

Fast measurements and easy control of external components

The R&S®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 R&S®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.
