(3) When using high frequency or square waves, terminate the device under test with a 50
Ω
adapter and use a cable that is as short as possible to reduce Ringing.
(4) To adjust output level of the generator exactly, use an oscilloscope or a wide band AC true rms
voltmeter.

4. Generating a pulse waveform
A sine or square wave has symmetry of 1:1, which means the time and shape of the positive alternation
is equal to the time and shape of the negative alternation. This is the default state of the symmetry
control in this unit. The symmetry can be adjusted from a maximum of 14:1 to a minimum of 1:14 in a
scale from 0.00 to 99.9 so a pulse wave form may be generated from a square wave and a saw tooth
wave from the Triangle waveform as shown in figure 10. Setting the amount of symmetry may also
generate a skewed Sine wave. [Figure 10] shows the possible output waveform.
