SteppIR Sark-110 Antenna Analyzer: The SARK-110 series of antenna analyzers are pocket size, multipurpose precision instruments capable of analyzing antennas or networks, generating or detecting signals and performing Time-Domain-Reflectometry (TDR) measurements on transmission lines.
Typical applications include antenna verification and adjustment, impedance matching, component testing, cable fault location, coaxial cable parameter measurement, and coaxial cable cutting at precise electrical lengths. As a signal generator, they are ideal for receiver calibration, sensitivity testing and signal tracing.
The analyzers have full vector measurement capability and accurately solve the resistive, capacitive and inductive components of a load. The accuracy is excellent!
The SARK-110 series is designed for standalone operation but can be controlled from your desktop computer using SARK Plots for Windows and from your tablet or smartphone.

Free: Tektronix 492 Graticle NOS: This is an original Tek NOS graticle screen for a Tektronix 492 spectrum analyzer. It is still in the protective wrapping and has not been opened. It has a small broken piece in one corner that I just noticed. Therefore I can’t in good faith sell it, but will give it first person who will send me a SASE padded envelope for me to ship it to you. It is glass so put a stiffener in there with enough postage to get it to you.; Listing #1754822 - Submitted on 01/05/26 by Callsign WD4RBJ - IP: 74.115.244.135; Click to Contact -- Click Here to View Picture -- Send this Ad to a Friend
