The working of the frequency counter can be explained from the above circuit diagram. The pulse generated from the square wave generator (Arduino UNO) is given to the pin 3.5 (port 3) of 8051 microcontrollers. Pin 3.5 of 8051 acts as timer 1 and configured as a counter. TCON TR1 bit ca...
Certain RF output circuitry and/or board layouts may result in issues with harmonics when tuned to an RF frequency below 200-250 MHz - a frequency counter can display a harmonic frequency under these conditions.Error codes:Common to SetStepFreq/setf/setrf:ADF4355_ERROR_NONE...
Feed the signal to one counter and let it count to1 (or whatever pressing factor you need). A second timer is clocked at max clk in free running mode. Use the first counter to generate a DMA event to copy the counter value from the freerunning one to memory. Now configure the DMA t...
The most important part for the accuracy of the frequency counter is the time base setting circuit – crystal resonator X1 and capacitors C4 and C5. C4 and C5 values can be between 33pF and 62pF and the crystal frequency can be fine tuned with them. The input of the schematic is feed ...
The instrument available produces frequencies from 0.1Hz to 2500Hz with a stepping frequency of 0.1Hz. Frequency calibration was carried out using a frequency audio counter in the frequency range of 300Hz - 500Hz. The maximum relative error of the first frequency source and the second frequency ...

The counter can measure up to 920-930kHz which is more than enough for my project. The reason why it can’t go higher is because driving all these digits consumes lots of CPU cycles. I suppose, the program code can be optimized or even written in assembler and then the counter can rea...
