4.1 Turning on

Plug the power supply into the mains and con-
nect it to the function generator.
This immediately turns on the equipment so that it is
ready to use. The top line of the display will indicate
the current frequency while the bottom line shows
the DC offset and the waveform.
4.2 Setting the frequency

Use the frequency knob to set the desired fre-
quency.

Push in and turn the knob to select the digit to be
changed on the display and then turn the knob
to set the specific frequency.
The active digit will be indicated on the display by a
flashing underline character.
4.3 Setting the offset

Press the Offset button to activate offset adjust-
ment.

Turn the frequency knob to set the required
value in steps of 0.1 V.
Pressing in the frequency knob resets the value back to
zero.

When the desired value has been set, Press Offset
again.
4.4 Selecting a waveform

Press the waveform button until the waveform
you want is indicated on the display.
It is possible to select a sine wave square wave or
triangular wave.
4. Operation
4.5 Sweep

Press the Sweep button to activate sweep mode.
The initial frequency is shown on the top line of the
display, while the bottom shows the DC offset, the
waveform and the word "START".

Turn the frequency knob to set the desired initial
frequency as described in section 4.2.

To set the frequency for when the sweep stops,
press the Sweep ´button again.

The bottom line of the display will show the word
"STOP".

Turn the frequency knob to set the desired fre-
quency for when the sweep stops.
Pressing the Sweep button again now sets the
equipment into sweep mode. The sub-modes Exter-
nal, Internal Continuous or Internal Single will be in-
dicated on the top line of the display.

Turn the frequency knob to select the desired
sub-mode for the sweep function.

Press Sweep again.
If external mode has been selected, then "EXT" will
be displayed at the bottom right of the display. If in-
ternal mode was display, the word "TIME" will be dis-
played there.

Adjust the sweep time by turning the frequency
knob and press Sweep again.
The start frequency will be shown on the display and
the word "READY" will appear at the bottom right.

Press Offset/Start/Stop to start the sweep.
While the sweep function is operating, the current
frequency will be indicated on the top line of the dis-
play, while the bottom line shows the DC offset, the
waveform and the word "RUN". The sweep can be
paused by holding down the Offset/Start/Stop but-
ton. Pressing it again allows the sweep to continue.
The word "BREAK" will be displayed while it is
paused.

To exit sweep mode press Sweep again.
In order to modify the values, it is necessary to exit
sweep mode and initiate the procedure again. It
should be noted that the DC offset cannot be altered
by this means.
