Control elements
DISPLAY (7-segment LED + LED)
3-digit frequency meter. The accuracy is
±1 digit. LED indicators for Hz and kHz.
FREQUENCY (4-position rotary switch)
Frequency coarse adjustment from 5 Hz to
50 kHz in 4 decade steps.
VARIABLE x0.1 – x1.0 (adjusting knob)
Continous frequency adjustment with over-
lapping ranges and a setting range from x0.1
to x1.0.
ATTENUATOR –20 dB, –20 dB (pushbuttons)
Two fi xed attenuators of –20 dB. They can be
used separately. When all buttons are pressed,
a total attenuation of 40 dB is obtained. Inclu-
ding the amplitude control AMPL.
attenu ation amounts to 60 dB (factor: 1000).
(pushbutton)
If this pushbutton is depressed, signal ground
and chassis (earth) are not connected; If relea-
sed, signal ground and chassis are connected
with each other.
SYNC. OUTPUT
(BNC connector)
Short-circuit-proof trigger signal output. The
signal is in-phase with the signal at OUTPUT
18

circuit. The output impedance is 1 kΩ.
OUTPUT 600 Ω (BNC connector)
Short-circuit-proof signal output of the gene-
rator. The output impedance is 600 Ω.
AMPL. (adjusting knob)
Continous adjustment of the output amplitude
from 0 dB to –20 dB if the OUTPUT 600 Ω
terminated with 600 Ω.
