Copper Mountain Technologies ACM2520

The Copper Mountain Technologies ACM2520 is a metrology-grade automatic calibration module that eliminates manual VNA calibration setup and execution. This fully automatic, USB-controlled instrument performs one-port through four-port calibrations across 100 kHz to 20 GHz (18 GHz for Type N models), delivering factory-characterized accuracy with minimal human error. The module operates over a 50 Ohm impedance, features eight reflection states per port plus a thru state, and includes a factory-characterized 20 dB in-line attenuator for DUT simulation and confidence verification.
