The R&S ZNLE vector network analyser from Rohde & Schwarz brings high RF performance and fast measurements to the economy class. The easy-to-use instrument is said to be the lightest, most compact VNA in its class, making S-parameter measurements easy.

Rohde & Schwarz has launched the R&S ZNLE vector network analyser to address the requirements of customers looking to perform RF measurements to characterise components such as antennas, attenuators, filters and PCBs. The standalone instrument weighs only 6 kg and has a footprint of just 408 x 235 mm, saving up to two-thirds of space on the workbench compared with competitor VNAs, according to the company.

The two-port vector network analyser not only saves space but also provides quick measurements due to its easy-to-use S-parameter wizard. The R&S ZNLE performs bidirectional measurements of the S11, S21, S12 and S22 S-parameters. An optional GPIB interface is available for remote control of the analyser. The instrument comes in two models with frequency ranges from 1 MHz to 3 GHz (R&S ZNLE3) and to 6 GHz (R&S ZNLE6).

The R&S ZNLE offers good RF performance with a wide dynamic range of typically 120 dB and measurement bandwidths from 1 Hz to 500 kHz. Measurement time is just 9.6 ms for 201 points at 100 kHz measurement bandwidth, for a 200 MHz span, with two-port TOSM/SOLT calibration. For stable, repeatable measurements, the R&S ZNLE produces low trace noise of typically 0.001 dB. Another feature is the large 10.1″ WXGA touch screen, providing good visibility of all traces.
