The wave generator is available through the WAVEGEN menu, shown below. To access
this menu, press the softkey under MODE until “wavegen” appears.

You can press the MODE softkey to cycle through the functions in the order shown, or
you can press P to return directly to the OTHER modes menu.
Each option in the WAVEGEN menu is described below:
• OUTPUT @ SCOPE Indicates the location of the signal output. If the signal does
not appear on the oscilloscope, press O. To disconnect the signal, press Y.
• WAVE Scrolls through the three types of waveforms that are available. You can
select a square, sine, or triangle wave as the output.
• SCOPE Z Toggles the calibrator’s output impedance setting between 50 Ω and
1 MΩ.
• OFFSET Displays the offset of the generated wave. To change the offset, key in the
new value, and press E . Using the rotary knob does not change the offset; it
changes the actual voltage output.
When you change the offset, you must remain within certain limits to avoid clipping
the peaks. The limit depends on the wave’s peak-to-peak value. Specifically, the
peak excursion equals the absolute value of the offset plus half of the wave’s peak-
to-peak value. See “Wave Generator Specifications” at the beginning of this chapter.
• MODE Indicates you are in WAVEGEN mode. Use the softkey to change modes
and open menus for other oscilloscope calibration modes.
Default Wavegen settings are 20 mV p/p, 1000.0 Hz, WAVE = square, and
offset = 0.0 V.
