output of the generator. The capacitance of this isolating capacitor should be
selected in such way that the frequency response of the output signal is not
affected over the whole frequency range of the
unit.
In the sine, square and triangle modes, the trigger output (at back panel)
supplies a square signal in synchronism with the output signal. An offset voltage
adjusted at the 50
output has no influence upon the trigger signal. The trigger
output is short-circuit proof and can drive several TTL inputs.

automatically given by the settings of the range selector and the frequency dial
and is shown on the 4-digit display. Start frequency is related to the stop-

potentiometer and is upto approx.100. The sweep speed is set by means of the
(Sweep) Speed potentiometer and ranges from 20 ms to 4 s. For external
wobbulation please refer to "FM input".
If a positive DC voltage is applied to the FM input on the rear BNC of
, the generator frequency increases and is accordingly displayed. A
negative DC voltage reduces the frequency.
The frequency displacement depends on the value and polarity of the DC voltage
U and on the FREQUENCY setting. The set frequency No (DC voltage not
included) can be selected at will.

No = digit display without voltage U.
N = digit display including voltage U
U = ± voltage at the FM input.
A = 740 (digits per volt).
It should be noted that only the displayed digits are valid; the decimal point is not
taken into consideration (e.g. 100.0 1000 digit). The max. frequency (3 MHz)
cannot and "000" should not be exceeded. Any zeroes preceding the decimal
point are dropped.
If the highest displayed number is N = 3000 and the smallest No = 300,
N = No + A.U
U = (N-No)/A
