ACM4520 Automatic Calibration Module (VNA)

ACM4520 is an automatic calibration module that can be used with all CMT Vector Network Analyzers operating in frequency range up to 20 GHz. It is a fully automatic USB-controlled and powered electronic calibration module. Minimizing the number of steps required by technicians reduces the risk of human error and expedites the calibration process. Automating the calibration routine also reduces wear and tear on the analyzer and RF cables. To perform full two-port calibration, each end of the ACM need only be connected to the analyzer once, as opposed to 18 connections with a traditional calibration. The ACM also contains a factory characterized 20dB in-line attenuator which acts as a simulated device under test (DUT).
