Rohde & Schwarz ZNLE 1MHz – 6GHz Vector Network Analyzer Review, Teardown & Experiments
 
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.
