Test set

 

The test set is made up of independent reflectometer units, each with a generator path, a measurement receiver, and a reference receiver for each test port. Electronic switches for forward/reverse switchover of measurement paths are not required in the test set. The use of the reflectometer concept allows each test port to carry out measurements like a one-port network analyzer.

This new hardware concept allows parallel measurements on different DUTs or different ports of a DUT. Data processing is likewise in parallel up to the display, which considerably reduces measurement time. For example, the reflection parameters (S11 to S44) of four DUTs can be measured in parallel, reducing measurement time by a factor of four. Measurements are performed and data is transferred via IEC/IEEE bus or LAN virtually at the same time.

The analyzer's frontend receivers are based on a fundamental mixing concept, which has already proven successful with the R&S® ZVR family. This concept provides a wide dynamic range of typically 130 dB and low trace noise at large measurement bandwidths. The test port output power can be electronically varied by more than 50 dB, allowing nonlinear parameters of active components to be measured quickly and wear-free. When measuring active components, the required DC power is input via the PORT BIAS 1 to 4 BNC rear-panel connectors and supplied to the components via the inner conductors of the analyzer's RF test ports. The R&S®ZVB also features two rear-panel inputs (1 V DC MEAS and 10 V DC MEAS) for measuring low-frequency AC voltages.
