Logic Analyzer - Frequency Counter
FPGA based 16 channel 200MHz / 32 channel 100MHz logic analyzer sump.org
The project includes the actual analyzer in VHDL (for Spartan 3 FPGA) and a PC Software for the end user. The design employs a FPGA board that can be obtained easily.
Features
- 16 channels at 200MHz sampling rate
- 32 channels up to 100MHz sampling rate
- state analysis up to 50MHz using external clock
- connects via EIA232/RS232 (works with usb to serial adapters)
- More....
100Mhz frequency counter and timer - Hardware, AVR, ATmega, ASM, Electronics, HF
In counter mode it provides 1Hz resolution up to 100Mhz. In timer mode maximum resolution is 0.0000001 Hz up to 1Hz. Resolution is reduced by one digit for each additional decade. Multiple frequency updates per second by employing a sliding window for calculation.
