eCal-Module 10MHz-67GHz, 2-Port, with option: M0F = 10MHz-67GHz ECal, one male and one female connector The N4694A MW electronic calibration (ECal) module makes calibration of vector network analyzers fast, easy and accurate. The RF ECal system is now easily controlled by one of two methods depending on the network analyzer. The Keysight PNA and ENA series of network analyzers controls the module directly via the USB interface. Frequency range:10 MHz - 67 GHz USB interface for direct control with PNA and ENA series of network analyzers Fast calibration Full two-port calibration with a single connection Reduced connector wear NIST traceable accurate calibrations Reliable solid-state switching
