Why Is My Generator Voltage Fluctuating Understanding Generator Why is the output voltage on my function generator twice my setting? in this video, we explain how to avoid a common impedance mismatch problem when using function. You are running the output (presumably a 50 ohm or 600 ohm output) into an open circuit (the o scope) hence you see approximately twice the value that is displayed on the function generator.
Why Is My Generator Voltage Fluctuating Understanding Generator If the function generator output is not terminated into a 50 ohm load, it may be necessary to adjust the output voltage to compensate for the different impedances. Typically you have a setting in the function generator for high impedance or 50 ohm. when you select 50 ohm, the generator will output a signal twice as high to compensate. in summary, this behaviour is normal. your generator has an output impedance of 50 ohm. When a high impedance device such as an oscilloscope is used to measure the output of the function generator, the waveform appears to be twice the voltage shown on the display of the function generator. One way to get the proper voltage is to place the scope input channel to the 50 ohms setting. if this isn't working, then there is something wrong with the output driver of the generator.

Why is the output voltage on my function generator twice my setting? when a high impedance device, such as an oscilloscope is used to measure the output of the function generator, the waveform appears to be twice the voltage set on the display of the oscilloscope. This video reviews the two most common reasons why the output amplitude setting on a function or signal generator doesn't match what is read on an oscilloscope. The 50 ohm output impedance and 50 ohm load form a 2 to 1 voltage divider. therefore, the actual internal function generator voltage that is produced is twice your set value, v set, to produce an output voltage on the 50 ohm load equal to your setting. When a high impedance impedance (r) can be calculated as device such as an oscilloscope is used to measure the output of the function vmeasured=v [r (r 50)], generator, the waveform appears to be twice the voltage shown on the where v=2 x display or display of the function generator.
