Function Waveform Generator Mode

General Description

Press the front panel F.G button to switch from arbitrary waveform generation mode into function waveform generation (FG) mode. Select the desired waveform with the bottom button. Then set the output parameters with the side button. Hereafter, function waveform generator mode will be referred to as FG mode.

NOTE. FG mode is an independent of the MENU column arbitrary waveform generation mode menus. Therefore, the output parameters set with the SETUP menu and the operation mode set with the MODE menu have no effect in FG mode.

The following waveforms may be selected from the bottom menu:

Sine wave

Triangle wave

Square wave

Ramp wave

Pulse wave

The following output parameters for these waveforms may be set from the side menu:

Frequency

Amplitude

Offset

Polarity

Duty (pulse wave only)

When a sine wave is selected, a 20 MHz cut-off filter is inserted. Table 3-24 shows the relationship between the frequency, the data point count, and the marker signal width.
