Siglent extends SNA5000A VNA to 26.5GHz

The development of radio and mobile communication technologies has led to an increase in applications in the microwave frequency range. In response the measurement technology market is developing and optimising the verification of active and passive components and networks. Siglent has introduced two models to expand its SNA5000A vector network analyser (VNA) series. 

The two new models are available in 13.5 and 26.5GHz bandwidths. They join the HF generator SSG5000A (up to 20GHz) and the spectrum analyser SSA5000A (up to 26.5GHz).

While the existing models are available as two or four-port analysers, the SNA5022A and SNA5032A are only available as a two-port version for the time being. The dynamic range spans 125dB and enables, for example, a precise analysis of the stopband of a filter without losing sight of the passband. All typical S-parameters and, with the four-port devices, all differential S-parameters can be measured. The company’s SNA5000-TDA (time domain analysis) or SNA5000-TDR (advanced time domain analysis) it is possible to carry out analyses in the time domain. This includes, the display of the eye diagram and the measurement of jitter. As an option, the series can also be supplemented with spectrum analyser functionality.

The accuracy of a network analyser is closely linked to the accuracy of the calibration. Depending on the application, different calibration techniques are necessary to obtain optimal results. The SNA5000A series offers a variety of options, including the changeable reference plane, port matching and embedding / de-embedding of test sockets to reduce external influences. 

The SNA5000A series VNAs offer five sweep types: linear and logarithmic frequency sweep, output power sweep, time domain sweep, and segmented sweep. The formula editor and the mask test support the developer in the analysis of the test object and accelerate the evaluation and verification. The large 12-inch touchscreen can be configured so that several windows with different measurements can be clearly displayed. The shortcut menu helps with configuration and offers quick access to the most important functions. There is also external mouse and keyboard support and the VNA can be controlled from the computer with the integrated web server without external software.
