AVT964 A

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
