PE4302 RF Attenuator
Features
- This is a PE4302 numerical control RF attenuator module.
- The parallel immediate mode is simple and easy to use.
- Bandwidth is wide and can be 1MHz to 4GHz.
- Program control gain attenuation range is from 0 to 31.5DB.
- The module supports parallel port and serial port mode as well as power on state selection function.
