Thank you again for the details, Gerry. I've went ahead and ordered the THS7002EVM. One thing I've noticed however is that its input impedance is 50 ohms (regardless of the 2 channels being used, there's a 50 ohm resistor connected to the ground for each), while the function generator modules of the...

Thank you for the detailed reply, Gerry. To begin with - one of the “generator”’s (Phidget 1018) digital output is controlled by my code running on the PC. At specific time intervals the code either sets the output level to off (0V) or to on (5V). So as you said the pulse width is determined coarsel...

Hi, I’m trying to determine the precision of a model railroad speedometer – the one here – in effect a device that measures revolution speed of the locomotive wheel and sends this across as a number to the PC constantly. By doing some analysis, this speedometer is composed of a rotary encoder that s...
