ACM6000T 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 300 kHz to 6 GHz. For higher frequencies, the ACM8000T operates up to 8 GHz.
The ACM calibrates any CMT VNA in fully automatic mode through the built-in functions of the analyzer software. The ACM 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 ACM memory.
Advantages of Automatic Calibration
The ACM 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 ACM 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. ACM6000T has six reflection states (three for each port) and a Thru, and ACM8000T has ten reflection states (five for each port) and a Thru. The precise S-parameters of the calibration impedance states are stored in the ACM memory (factory characterization data).
Basic configuration options for ACM6000T are below.
ACM6000T (300 kHz to 6 GHz):
- N-Type M-F
- N-Type F-F
- 3.5mm M-F
- 3.5mm F-F
Because the ACM comes in multiple configurations and connectors, we advise you to talk to us to see which one is best for your application.
