Device for measure crystals, adjusting and fine tuning of quartz filters.KIT DiY
This design is developed for adjust a ladder quartz filters with the same resonators.
The stand is made on a single-sided printed circuit Board with a size of 150x90 mm and consists of a stabilized generator and a breadboard for crystals.
The buili-in generator is assembled on the transistor and coil, frequency tuning is carried out by trimming capacitor. On the breadboard – quartz filter and jumpers that are connected to the generator and the output sockets of the stand. In the circuit of the breadboard there are seven trimming capacitors, which, if necessary, can be connected to the filter to adjust its parameters.
The RF voltmeter or a conventional RF probe should be connected to the output sockets of the stand.
What is in a kit: - documentation, PCB 150х90 mm, all elements necessary for assembly.
The manual has data for 8-10MHZ crystals. If need use another frequencies, than need to change the quantity of winding of the coil.
KIT consists of necessary componets for assembly.
