The R&S®ZVB series of vector network analyzers covers the frequency ranges from 300 kHz to 4/8 GHz.
It has been designed for universal measurements on passive and active components. The R&S®ZVB series greatly simplifies vector
network analysis especially for multiport measurements and measurements on balanced devices. Featuring comprehensive measurement
functions, excellent specifications, high measurement and data transfer speeds and remote-control capability, the analyzers of the R&S®ZVB series are an ideal choice for both development and production applications.
Key Facts:
New multiport concept:
- Instruments with two or four test ports – for multiport and balanced measurements
- Two internal sources (four-port models) – to provide RF and LO signals for mixer measurements by means of a single unit
- Capability to perform balanced measurements – to characterize balanced DUTs by their mixed mode S-parameters
- Optional automatic calibration units – to speed up calibration and avoid operator errors
Outstanding specifications:
- 60001 points per trace
- Dynamic range better than 123 dB (typ. 130 dB)
- Power sweep range >50 dB
High speed:
- Measurement time < 4.5 ms for 201 test points (frequency sweep)
- Switching time between channels < 1 ms
- Switching time between instrument setups < 10 ms
- Data transfer time < 0.7 ms (201 test points via RSIB)
- Simultaneous measurement of more than one DUT
Modern user interface
- Intuitive Windows-based operation via mouse
- Operation by means of hardkeys and softkeys
- Large number of channels, traces and setups that can be loaded simultaneously
Features:
Wide range of functions for increased throughput
The new platform of the R&S®ZVB employs a fundamental mixing concept that has proven successful in the R&S®ZVR
series of vector network analyzers for more than ten years and that ensures a wide dynamic range of up to 123 dB
and low trace noise better than 0.01 dB. Measurement bandwidths range from 1 Hz to 500 kHz. A frequency sweep covering
201 test points takes less than 8 ms at a bandwidth of 500 kHz.
Measurement speed can be further optimized by means of a segmented sweep. This function allows you to divide a sweep into as many segments as you like,
their number being limited only by available RAM size. Sweep parameters such as the number of test points, the test point
spacing, the measurement bandwidth, and the source level can be defined separately for each segment and thus accurately adapted to the DUT characteristic.

Different setups can be stored on hard disk and loaded into RAM as required.
Several setups at a time can be loaded into RAM. Since all data of loaded setups, including calibration data,
is already in RAM, you can switch between setups (setup swapping) virtually without delay, i.e. in less than 10 ms
by remote control. With conventional instruments, recalling setups can take up to one second. Each setup is represented
by a separate measurement window. In manual operation, you can switch between windows by using the mouse or pressing a key.
Setup swapping
Trace data is transferred via the IEC/IEEE bus or LAN at the same time measured data is being captured, which means that data transfer time on the R&S®ZVB is insignificant.
The multigenerator concept of the R&S®ZVB allows test ports to be organized in groups. Each test port group carries
out measurements independently of the other groups; the measurements of all groups are performed simultaneously,
provided the test parameters are identical for each group. This allows several DUTs, or several paths of one DUT,
to be measured in parallel. The dialog for defining test port groups is shown below.
