Munich, Germany. Rohde & Schwarz has launched the R&S ZNLE vector network analyzer to address the requirements of customers looking to perform RF measurements to characterize components such as antennas, attenuators, filters, and PCBs. The new standalone instrument weighs 6 kg and has a footprint of 408 mm x 235 mm, saving up to two thirds of space on the workbench compared with competitive VNAs, the company said.
The R&S ZNLE offers 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 a 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.
The R&S ZNLE features a 10.1” WXGA touchscreen, providing good visibility of all traces. The touchscreen supports zooming in and out of traces using multitouch gestures. The user interface makes it possible to access every function with a minimum number of steps. Undo/redo softkeys are available to cancel and restore user entries. Context-sensitive help menus for the diverse functions and parameters facilitate interactive operation.
Calibration of the instrument is straightforward. The R&S ZNLE incorporates the calibration wizard used in other Rohde & Schwarz R&S ZNx analyzers. Calibration units are also supported. A “Start Auto Cal” function delivers automatic calibration at the touch of a button.
