INPUT TREATMENT TO THE FREQUENCY METER - PLATE

Producer: AVT

An important element of each frequency meter is the entrance track. It is important that it is sensitive enough and works to the frequency required by the user. These features have a set presented. It has two measuring sub-ranges. RF path works to 1.1 GHz frequency. The system has a built-in prescaler. Sensitivity of the measuring system is smoothly controlled by a potentiometer.

The device is especially recommended for users of self-made frequencies, also for those who want to modify the factory production equipment

Selected parameters:

  • two measuring sub-ranges
  • common entrance for the MW and RF ranges (switching paths with logic level)
  • sensitivity around 20mV
  • working frequency: m.cz. - 5 Hz - 75 MHz; HF path - 70 MHz - 1.1 GHz
  • input resistance of the track 1 Mom
  • maximum amplitude of the MW signal 6 V (the limiter works above)
  • built-in divider by 1024 (switched on by logic level)
  • power supply - 15 Vdc
  • printed circuit board and documentation included
