R&S®ZVA-Zxxx Millimeterwave converters

Frequency range

• 60 GHz to 90 GHz (R&S®ZVA-Z90);
• 75 GHz to 110 GHz (R&S®ZVA-Z110/R;&S®ZVA-Z110E)
• Using an R&S®ZVA24/40/50/67 or an R&S®ZNA26/43/50/67 network analyzer

Wide dynamic range

• R&S®ZVA-Z90: > 100 dB, typ. 115 dB
• R&S®ZVA-Z110: > 100 dB, typ. 110 dB
• R&S®ZVA-Z110E: > 95 dB, typ. 110 dB

Variable and electronic output power

Typ. +10 dBm (R&S®ZVA-Z90);
Typ. +10 dBm (R&S®ZVA-Z110);
Typ. up to +2 dBm (R&S®ZVA-110E);
A control screw can reduce power by 40 dB (R&S®ZVA-Z110). The output power can be electronically reduced by 25 dB with the R&S®ZVA-Z110E. The R&S®ZVA-Z110 can reduce it by 70 dB with RF input power variation.

Automatic parameter setting

R&S®ZVA and R&S®ZNA firmware runs the converters with the R&S®ZVA-K8/R&S®ZNA-K8 converter control option. The network analyzer will automatically set the correct parameters based on the selected converter type. The network analyzer also protects converters by limiting output power to the converter coaxial inputs. Appropriate calibration is available for each converter band.

Convenient handling

The converter waveguide connectors are arranged on a bar extending from the converter for convenient usage. The screwed flange joints are easily accessible for calibration and connecting the DUT. The converters can have three or four height-adjustable feet. Three feet make it much easier to align the test-port flange. The converters have no fans – a big advantage in particle-sensitive environments.

Multiport and true differential measurements

Multiport devices such as couplers can be analyzed with three or four converters. The setup can use an R&S®ZVA24, R&S®ZVA40, R&S®ZVA50 or R&S®ZVA67 plus an external generator and one converter per test port. The R&S®ZNA26, R&S®ZNA43, R&S®ZNA50 or R&S®ZNA67 enable up to four converters, which can be connected without needing an external signal generator. The R&S®ZVA-Z90/R&S®ZVA-Z110 and the R&S®ZVA-Z110E are ideal for generating true differential signals (true differential mode).

Pulsed measurements

The converters can also be operated in pulsed mode − to characterize pulsed amplifiers. This applies to both measurements versus frequency (average pulse and point-in-pulse) and pulse profile measurements.
