VLl
On/off switch with neon indicator
Continuous frequency control
Frequency control in steps. The output frequency
given in Hz is equal to the product of the setting
of SK3 and the setting of RI.
Continuous control of the amplitude at both
output terminals BUl and BU4.
Switch for setting the attenuation of the ampli-
tude at terminal BU4 in four steps of 20 dB, viz:
—60 dB, —40 dB, —20 dB and 0 dB.
Switch for selecting the output waveform at the
terminals BU1 and BU4.
The output voltage at this terminal may be varied
continuously by means of R2.
The output impedance is l0 S2 for the square wave
and 16 f2 for the sine wave.
