In this episode Shahriar reviews the Rohde & Schwarz ZNLE 1MHz – 6GHz Vector Network Analyzer. The ZNLE is the economy model of the ZNL 3-in-1 instrument. The R&S ZNLE is a two-port vector network analyzer that can be used for bidirectional measurements of S-parameters S11, S21, S12 and S22 on passive components. Ordering the RR&S ZNLE requires only two decisions: the frequency range and whether or not you need a GPIB interface. The analyzer is available with a frequency range of 1 MHz to 3 GHz (R&S ZNLE3) or 1 MHz to 6 GHz (R&S ZNLE6). The optional GPIB interface lets you connect a controller to remotely control the R&S ZNLE. As a standalone instrument, the R&S ZNLE does not require an external PC to configure the setup. You can start measuring immediately after you switch on the instrument. The review is organized as follows: 01:12 – Model comparison and overview. 02:24 – Instrument overview and design. 06:29 – Brief teardown and internal construction. 09:31 – Electronic Calibration Unit and auto-cal procedure. 17:39 – Measurement and characterization of a tunable microwave filter. 30:47 – Measurement of a tunable phase shifter. 33:16 – Analysis and measurement of a trice coupled quad-patch antenna module. 39:10 – Performance and characterization of an ZNLE internal synthesizer. 46:31 – Mixed-mode S-Parameter measurements using the ZNLE. 49:15 – Extreme dynamic range measurements using a 0.1dB step electromechanical attenuator. 1:02:48 – Overview of additional functions. 1:04:26 – Concluding remarks.
