A milestone for R&S®ZNA based enhanced amplifier and converter testing

Two models with frequency ranges from 10 MHz to 44 GHz and 67 GHz

The R&S®ZN-ZCG comb generator is designed for a precision phase calibration of the R&S®ZNA vector network analyzer. It offers a phase-characterized spectrum for frequency harmonics, serving as a reference signal for phase calibration in wideband receivers. Utilizing the proven R&S ZNA SMARTerCal technique, it features an intuitive graphical user interface to facilitate the calibration of all ZNA ports, similar to a standard calibration unit.

Features & benefits

Complementary wideband phase calibration with a single connection

Simplify harmonic and mixer sideband phase tests using the R&S®ZN‑ZCG

Harmonic or mixer sideband phase calibration often needs extra hardware, increasing setup complexity. The R&S®ZN‑ZCG simplifies this with a single connection to an R&S®ZNA port. Covering 10 MHz to 44/67 GHz, its RF output works with R&S®SMARTerCal to calibrate all measurement and reference receivers in one step. Once calibration is complete, all ports are free for measurement, maximising efficiency and minimising effort.

Seamless integration into the R&S®ZNA error correction concept

Phase calibration made native to the R&S®ZNA workflow with R&S®ZN‑ZCG

The R&S®ZN‑ZCG fits directly into the R&S®ZNA error correction process, with built-in GUI control and no need for extra sequences. SMARTerCal enables single-port connection while calibrating all receivers automatically. Calibration is quick, efficient, and does not interfere with measurement availability.

Optimization features

Advanced Optimisation for Precise Wideband Phase Calibration

The R&S®ZN‑ZCG functions as a high-speed pulse generator, producing evenly spaced pulses that translate into a comb-like spectrum. Each spectral line's magnitude and phase is factory-characterised, forming the basis for precise calibration of all R&S®ZNA receivers. With pulse widths under 20 ps and selectable frequency spacing from 1 MHz to 100 MHz - or even user-defined up to 2 GHz - the system adapts to diverse setups.

Easy system integration for various applications

R&S®ZN‑ZCG adapts to your system with effortless integration

The R&S®ZN‑ZCG supports precision phase calibration across varied setups, enabling reliable harmonic phase analysis in amplifier LSA, mixer testing, embedding/deembedding, and waveform reconstruction. Its flexible calibration approach supports full frequency spans or setup-specific bands, ensuring accurate, system-integrated results in demanding RF applications.

Three operation modes

Flexible Operation with Three Versatile Modes

The R&S®ZN‑ZCG offers three operational modes:

R&S®ZNA system error correction (adding wideband phase calibration)
Evaluation for verification and optimization
Stand-alone and system integration
