User Manual
First Time Operation
After unpacking the instrument check for any mechanical damages. The
instrument should be plugged in mains-plug of proper mains supply 230V
10%.
±
On switch ON no undue observation should be noticed. Once the instrument is
switched ON, the power ON is indicated by liting of displays.
Function Selection
The type of output signal is selected with the function selection switch
. A total
number of 5 different waveforms - sine, square, triangle ramp & pulse are
,
available apart from the DC level. The functions are marked with the corresponding
symbols. If the
"OFFSET
”
pushbutton
is activated a DC voltage level is supplied
by the
or superimposed on the output signal.

Frequency Adjustment
Coarse adjustment is performed with the range keys. The desired frequency is
selected by turning the FREQUENCY control
.
The selected frequency appears on the 4- digit display
. Compared to knob
scales, this display has a much higher resolution and accuracy.
Output Amplitude and Signal Connections
Adaptation in decade steps to the desired amplitude range is performed by the use
of two attenuators with -20 dB each, which are activated by pushbuttons
&
.
Including the continuously adjustable AMPLITUDE control
,the maximum
attenuation amounts to
–
60 dB. With the maximum amplitude of 10V , the
pp
minimum signal voltage to be supplied is about 10 mV. These values are obtained
when the generator output is terminated with 50
.in the open-circuit condition, the
W
available signal amplitude is twice as high. Therefore the maximum output voltage
of the output socket is specified with 20 V .
pp
If exact square-shaped signals are required, care should be taken that only 50
W
coaxial cables are used. Furthermore, this cable must be terminated with a 50
W
through termination. If these precautions are not observed, overshoot may occur,
especially when high frequencies are selected. If test circuits having a 50
input
W
impedance are connected, this termination is not required. In high signal voltage
