R&S®ZVA Vector Network Analyzers

The R&S^®ZVA series is an ideal choice for demanding measurements in the lab and in production – from filter measurements requiring maximum dynamic range to linear and nonlinear measurements on amplifiers and mixers as well as on receivers and transceivers.

The R&S^®ZVA has set milestones for the most challenging applications:

• First VNA with four internal sources up to 67 GHz for fast two-tone measurements on amplifiers and mixers
• First VNA up to 67 GHz that generates phase-coherent signals
• First VNA with IF bandwidths up to 30 MHz for pulsed measurements on amplifiers and mixers up to 110 GHz

The R&S^®ZVA contains one source per each pair of ports. In addition four source models are available for R&S^®ZVA24 and R&S^®ZVA40. TheR&S^®ZVA67 has one source per port. A special switch arrangement allows parallel signal output, i. e. signals can be output to the DUT via all ports at the same time. In addition, direct generator and receiver access is provided optionally. This concept offers many advantages with regard to measurement speed and functionality.

The above design features make the R&S^®ZVA an analyzer of unprecedented performance and functionality, which is especially true for the four-port model. Following are a few highlights:

• Use of the second source as an LO for fast mixer measurements
• Generation of a swept two-tone signal for fast intermodulation measurements versus frequency or power
• True differential measurements on balanced DUTs
• Parallel signal output and measurement at the test ports for measuring two or more DUTs simultaneously.
• Direct generator / receiver access (option) enabling the following, for example:
  • Loop-in of preamplifiers into generator paths
  • Loop-in of attenuators into the receiver paths
  • Connection of external test setups, e.g. power amplifiers, or use of analyzer as a multichannel receiver, e.g. for antenna measurements

• Short measurement times due to fast synthesizers, wide IF bandwidths and high dynamic range

• More than 100 traces and channels
• Measurement wizard for easy setup of multiport and balanced measurements

• Versatile calibration techniques for test fixtures as well as for coaxial and on-wafer applications
• Automatic calibration with calibration unit

• Virtual and true differential mode for linear and nonlinear testing of differential components

• Simultaneous measurement of noise figure and S-parameters
• Wide power sweep range for small and large signal analysis in one sweep
• Second internal source for fast hot S₂₂, IMD and mixer measurements
• Phase and group delay measurements of the conversion loss on mixers and converters with and without LO access
• Conversion loss measurement of converters with up to three conversion stages
• Intermodulation measurements on mixers

• Direct access to the generators and receivers for 30 dBm output power and 150 dB dynamic range
• Time domain with linear prediction for increased resolution

• Easy setup of pulse profile measurements with 12.5 ns time resolution and up to 30 MHz measurement bandwidth

• Extension unit for the R&S^®ZVA with integrated combiner, pulse modulators and harmonic filters
