2.2.3.
Setting the frequency
The frequency can be adjusted in two different ways:
- continuously, with the frequency dial
- in steps, with the FREQUENCY Hz pushbuttons
The output frequency equals the product of the value on the frequency dial and the value of the selected
FREQUENCY Hz range pushbutton (e.g. frequency dial setting 1.9 x range switch 10 k =19kHz output
frequency).
2.2.4.
Setting the amplitude
The signal amplitude at the OUTPUT BNC socket is continuously variable by means of the AMPLITUDE
control to r.m.s. values between 0 V and 2 V.
An attenuation of 20 dB can be obtained by depressing the ATTEN pushbutton.
2.2.5.
Decreasing the settling time
When using the instrument in sinewave mode with low frequency values it is possible to decrease the settling
time by means of the LOW DISTORTION/FAST SETTLING switch, which is incorporated in the
AMPLITUDE control.
Pulling the AMPLITUDE control out selects the FAST SETTLING mode.
As a result of this, the distortion factor increases.
2.2.6.
TTL Impulse-signal output
A TTL-compatible squarewave signal with a duty cycle of 0.5 is available at the
IL
OUT socket. The
frequency of this signal is the same as that set for the other output.
