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.
