Questions tagged [function-generator]
A function generator usually refers to a piece of test equipment that generates a variety of waveforms over a range of frequencies. A typical unit may generate sine, square and triangle waves at a frequency up to around 20MHz, they tend to be less often used at higher RF frequencies.

50 ohm vs HiZ setting on function generator?
I got my first function generator today. The generator is a SDG1032X.
It gives you the option to switch between 50 Ω output and HiZ (high impedance) output by long pressing the output buttons.
It does ...

Dedicated ground vs power cord ground?
So my Siglent 1104X-E oscilloscope has no dedicated ground- it uses the power cord's ground.
My Siglent function generator has a dedicated ground (screw terminal with banana plug option). Obviously I ...
