ACM2708 Automatic Calibration Module (VNA)

ACM2708 is an automatic calibration module that can be used with CMT Vector Network Analyzers operating in frequency range up to 8 GHz. The ACM 2708 is a 75 Ohm calibration module for use with native 75 Ohm VNAs (SC7540) while also covering automatic calibration for 50 Ohm VNAs with the use of 50 to 75 Ohm matching pads. 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 seven 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).
