ACM2509 Automatic Calibration Kit

ACM2509 is an Automatic Calibration Module (ACM) designed for full one-port and two-port calibrations of vector network analyzers from Copper Mountain Technologies. It operates in the frequency range from 20 kHz to 9 GHz. 
For lower frequencies, the ACM2509 operates up to 9 GHz.

ACM2509 calibrates any CMT VNA in fully automatic mode through the built-in functions of the analyzer software. ACM2509 switches to the impedance states one by one in the process of calibration. The VNA calibration coefficients are calculated using the measured S-parameters of the ACM impedance states and the data stored in the ACM2509 memory.

Advantages of Automatic Calibration 
The ACM2509 calibration offers the following advantages over traditional mechanical SOLT calibration:

  • Reduced number of connections (for example, full two-port calibration requires only one connection of the ACM to a VNA instead of 7 connections of mechanical standards)
  • Faster calibration procedure
  • Reduced risk of human error
  • Higher accuracy
  • Reduced wear on test port connectors 

    The ACM2509 contains two RF connectors for connection to VNA test ports, Mini-USB control port, several different transmission and reflection impedance states and electronic changeover switches. ACM2509 has six reflection states (three for each port) and a Thru, and ACM2509 has ten reflection states (five for each port) and a Thru. The precise S-parameters of the calibration impedance states are stored in the ACM2509  memory (factory characterization data).
