To set the output amplitude
To set the output amplitude
At power-on, the function generator outputs a sine wave with an
amplitude of 100 mV peak-to-peak (into a 50Ω termination).
The following steps show you how to change the amplitude to 50 mVrms.
Ampl 1 Enable the amplitude modify mode.
The displayed amplitude is either the power-on value or the previous
amplitude selected. When you change functions, the same amplitude is
used if the present value is valid for the new function.
Enter Number 2 Enter the magnitude of the desired amplitude.
5 0

front panel. As soon as you select the units, the function generator
outputs the waveform with the displayed amplitude. To turn off the
flashing digit, move the cursor to the left of the display using the arrow keys.
