Hi, I require some help with a project to make my day easier.
I need to build two function generators, 22khz and 33khz.
Both sine wave
That will go through 5m of thin cable to earth.
At a constant 1mA, so I can trace the signal from above for test purposes.
Powered from any standard plug in power supply batteries not required.
I can find DIY kits but nothing seems to get to the KHz required.
I am no design engineer but have no issue building - could any body give me a point in the right direction please.
I know I can buy a complex sig gen but I want something with a simple switch that if broken wont hurt to replace.
