8.1.3 SETTING DC-OUTPUT
• The DC offset function can also be used to output a pure direct voltage without frequency overlay. Carefully push
one of the unpushed switches in the field “FUNCTION” just until all three switches “jump” into the un-pushed posi-
tion.
• If all three switches are not pushed, a pure direct voltage is pending at the output “OUTPUT”. The pulled adjust-
ment button “DC OFFSET” (11) can be used to set the DC level. Check the DC level with the DC voltage meter or
using an oscilloscope.
8.1.4 SYMMETRY SETTING
• For this, also observe chapter 8.2.
• The output signal can be adjusted via the symmetry setting. The signal increase is changed, which leads to a
• The output signal can be adjusted via the symmetry setting. The signal increase is changed, which leads to a
symmetry offset. This leads to the generation of pulse tips in rectangles or a saw-tooth signal for triangle.
• To activate this function, pull the adjustment button “SYM” until it latches. In the middle position, the signal is sym-
metrical; a turn to the left shortens the rising flank; a turn to the right shortens the dropping flank. This function is
off when the button is pushed.
8.1.5 SYNCHRONOUS OUTPUT TTL
• The synchronous unction outputs a TTL-rectangular signal with the signal frequency and symmetry independently
of the wave shape of the output signal (except for DC). At the BNC-socket “OUTPUT TTL SYNC” (6), a TTL-level
with fixed amplitude is pending. The frequency and symmetry of the TTL level are aligned with the basic signal.
The operating elements “AMPL” (signal voltage), “DC OFF-SET” and “ATT” (dampener -20dB) do not influence the
TTL-level.
8.2 “PULSE”-GENERATOR
The symmetry function “SYM” is used for application as pulse generator. For a standard signal such as sine, triangle
or rectangle or TTL, the ratio between positive and negative half-wave is 1:1. By pulling the adjustment button
“SYM” (12), the function “Symmetry setting” is activated, i.e. the ratio between positive and negative half-wave can
be changed by more than 10:1 (in either direction!).
A sine signal then turns into an elongated sine, a triangular signal into a ramp or saw-tooth function and rectangle or
A sine signal then turns into an elongated sine, a triangular signal into a ramp or saw-tooth function and rectangle or
TTL signal becomes a needle impulse.
