Hi,
I just purchased a GW-INSTEK GFG-8019G 0-2MHz function generator for a cheap price on eBay. It comes with no probe. When I got it home, I used my oscilloscope 1x probe (1MOhm input impedance) and connect it to the 50Ohm output socket and try the waveforms. Everything seems to work fine (triangular, square and sine wave) even at high frequencies. Up to 2MHz triangular and sine wave looks fine and not distorted whereas square wave are fine up to around 500kHz, beyond which it will look like a distorted sine wave, which I suspect is simply the limitation of this device.
So does this mean that I can use the 1MOhm oscilloscope probe with this function generator? Will it cause any other problem in the future? I don't need high accuracy, as long as the generated waveforms look ok.
