DIGITAL FREQUENCY METER - PLATE AND PROGRAMMED LAYOUT
Description
Modification of the AVT3003 set - digital frequency meter. One of the most important changes is the modification of the input circuit for the 100MHz range. The prescription U664 is used to measure higher frequencies. Inputs from both channels are switched electronically via a multiplexer. The introduction of modifications made it possible to power the meter from one voltage - it simplified the power supply. The way of displaying measurement results was also changed and the impulse counter function (rarely used) was abandoned.
The device is particularly recommended in electronic laboratories and the website
