Voltcraft 8202 Function Generator, Frequency Generator 8202 Data Sheet

28

The following table provides information about how and in which limits the offset level moves and when
the signal is clipped (at 50 Ohm).

Maximum amplitude setting

No DC offset

No distortion

Reduced amplitude setting

Low DC offset

No distortion

Maximum amplitude setting

Large DC offset

Strong distortion

• Via the DC offset function, it is also possible to output a real direct voltage without frequency overlay.

Gently press one of the unpressed switches in the field „FUNCTION“ until all three switches „jump“ into
this unpressed switch position. 

• If all three switches are not pressed, direct voltage is applied to the output „OUTPUT“. You can set the

DC level via the pulled adjuster knob „DC OFFSET“ (11). Check the DC level with a DC voltage meter
or an oscilloscope.

• You can change the output signal via the symmetry setting. The signal increase is changed, which

results in a shift of the symmetry. This generates pulse peaks with rectangles or a sawtooth signal with
triangles.

• To activate this function, pull out the adjuster knob „SYM“ (14). In central position, the signal is symme-

tric; left turns reduce the rising pulse edge, right turns reduce the declining pulse. When the button is
pressed, the function is off.

• The synchronous function outputs a TTL square signal with the signal frequency independent of the

wave form (except for DC). A TTL level with fixed amplitude is applied to the BNC socket “OUTPUT
TTL/CMOS” (6). The frequency and symmetry of the TTL level can be changed. The operating ele-
ments “AMPL” (signal voltage), “DC OFF-SET” and “ATT” (attenuator -20dB) do not influence the TTL
level.
