Atlas ESR PLUS - Equivalent Series Resistance Meter
ESR70
The Atlas ESR provides instant measurement of a capacitor's ESR and it's capacitance value. Using the supplied gold plated probes (removable), the Atlas ESR can measure ESR down to a resolution of 0.01 ohms, up to 40 ohms. It can even measure ESR for capacitors that are in-circuit. Measurements are made at the industry standard frequency of 100kHz. Probes are now removable, allowing 2mm compatible probes to be fitted. Audible alerts are produced for various ESR levels allowing you to perform many tests in succession without having to look at the display.

Full Band Phase Shifters
STP-18-10-M2
Full band phase shifters are micrometer-driven, waveguide-based phase shifters. The configuration of the micrometer-driven phase shifters is similar to that of level setting attenuators, where the phase shifting is caused by an E-plane dielectric insert in the rectangular waveguide. The amount of phase shifting is directly dependent on the volume of the insert. The VSWR and the insertion loss of these phase shifters are dependent on the frequency. The below standard offering covers the frequency range of 18 to 110 GHz and a phase shifting range of 180 degrees. These micrometer-driven phase shifters are typically used to introduce a certain amount of phase shifting when the absolute number is not a focus.
