Network analyzer from Rohde & Schwarz with a frequency range of 10 MHz to 110 GHz

Rohde & Schwarz has introduced a new high-end network analyzer, the R&S ZVA110, with a frequency range from 10 MHz to 110 GHz. The analyzer is suitable for measurements on passive and active components into the millimeter-wave range. Rohde & Schwarz millimeter-wave converters take the R&S ZVA110 beyond the 110 GHz limit and make it suitable for band-specific solutions in the range up to 500 GHz. This network analyzer can also perform frequency-converting pulsed measurements.

The R&S ZVA110 can characterize two-port DUTs with a continuous frequency range from 10 MHz to 110 GHz. The analyzer is suggested for applications such as vehicular radar and parking assist systems (at 77 GHz) for automobiles, general radar applications (e.g. at 94 GHz) or wireless backhaul applications in the 79/80 GHz range. The R&S ZVA110 is based on the R&S ZVA67 four-port network analyzer, which has a range of up to 67 GHz. Two frequency converters with electronic power control have been added to cover the range from 70 GHz to 110 GHz.

The electronic attenuator of the frequency converters allows power calibration and power sweeps, even for compression measurements on amplifiers above 70 GHz. The DUT can be connected directly via the 1 mm plug or it can be connected to a wafer prober, depending upon the type of application. The R&S ZVA67 base unit integrates four test ports, four integrated signal sources and eight receivers. This architecture allows the user to perform multiport measurements on amplifiers, mixers and balanced DUTs. The R&S ZVA110 can also measure short pulses with high resolution (12.5 ns in the pulse profile mode).
