Applications

• AC6912H: With support for frequencies up to 5000 Hz, it is ideal for testing high-frequency equipment such as aviation electronics, as well as for applications requiring operation at higher-than-standard frequencies.
• AC6912L: Designed for standard applications with frequencies up to 550 Hz, including testing consumer electronics and other devices operating at standard frequencies.
  
  

Choosing Between AC6912H and AC6912L

The choice between AC6912H and AC6912L should be based on the frequency range requirements of your testing applications. If testing devices at frequencies above 550 Hz is required, AC6912H is recommended. For standard applications with frequencies up to 550 Hz, AC6912L is suitable.
