Siglent introduces Entry-Level VNA Series
Siglents entry-level vector network analyzer series SNA5000X-E is now available on the european market. Covering frequency ranges up to 3 GHz and 6.5 GHz the VNAs target applications in embedded RF development, industrial electronics, education, and production testing.
The analyzers perform full two-port S-parameter measurements from 9 kHz up to the configured maximum frequency. This enables detailed characterization of filters, impedance matching networks, RF amplifiers, antennas, and interconnect structures used in wireless modules and signal integrity validation.
The availability of measurements starting at low frequencies supports broadband applications and mixed-signal designs. Engineers can verify impedance behavior across wide frequency ranges during early development stages, which is relevant for systems combining analog, digital, and RF functions.
Dynamic range and sensitivity
With a typical dynamic range of up to 125 dB, the instruments provide sufficient sensitivity to analyze both passive and active components. High stopband attenuation in filters or small reflection coefficients can be resolved, supporting accurate validation of RF circuits and front-end modules.
Calibration in practical setups
Integrated calibration methods such as SOLT and TRL enable accurate measurements across different test environments. This includes laboratory setups as well as fixture-based measurements using adapters, custom test fixtures, or PCB structures. Flexible calibration is required in these scenarios to maintain measurement accuracy despite additional signal paths.
Time-domain analysis and fault localization
In addition to frequency-domain measurements, the series supports time-domain transformation. This allows identification of impedance discontinuities along cables, connectors, and PCB transmission lines. The functionality is used in troubleshooting during prototype validation and in optimizing signal integrity in high-speed interconnects.
Differential measurements and de-embedding
Differential and balanced measurement techniques are included to support modern RF and mixed-signal designs that rely on differential signal paths. Fixture simulation and de-embedding functions help remove the influence of the measurement setup from the results. This isolates the behavior of the device under test and improves correlation between simulation and measurement.
Additional analysis functions
Receiver measurement capabilities extend the use of the instruments to applications requiring characterization of signal transmission and conversion behavior within RF subsystems. An integrated spectrum analysis function provides additional visibility during debugging and validation, reducing the need for separate instruments in compact lab environments.
Integration into test environments
The instruments support integration into automated test systems via LAN and USB interfaces, with SCPI-based remote control. This enables use in production verification setups and teaching laboratories where repeatable measurement procedures are required. A multi-window touchscreen interface allows simultaneous display of multiple S-parameters for efficient analysis.
Typical applications
Application areas include validation of embedded wireless modules, antenna matching, RF filter characterization, cable and interconnect testing, and signal integrity analysis in mixed-signal hardware. The instruments are also suited for educational use in RF measurement techniques, where combined functionality and frequency coverage are required.
