R&S ZNLE vector network analyser

The R&S ZNLE vector network analyser is suitable for users looking to perform RF measurements to characterise components such as antennas, attenuators, filters and PCBs.

The stand-alone instrument weighs only 6 kg and has a footprint of just 408 x 235 mm, saving space on the work bench.

The two-port vector network analyser provides quick measurements due to its easy-to-use S-parameter wizard. The product 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 product provides 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 product produces low trace noise of typically 0.001 dB. The product features a large 10.1″ WXGA touch screen, providing good visibility of all traces. The touch screen supports zooming in and out of traces using multitouch gestures. The well-structured user interface makes it possible to access every function with the 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 just as straightforward. The ‘Start Auto Cal’ function delivers automatic calibration at the touch of a button.
