Fig. 2-6. Triangle generator architecture.

External VCO Example:

To get a swept output from approximately 1 to 5 kHz:

•  Set  Frequency  to  11  kHz.
• Set  Range  Lock  ON  and  FM  mode  ON.
•  Set  a  ramp  generator  to  start  a  1  V  and  end  at

3 V.

This setup will provide a linear sweep of output

frequency from about 1 kHz to 5 kHz.

Frequency Lock.

With frequency lock on, internal

circuitry improves the generator's frequency accuracy.

For operation to specified frequency accuracy, fre

quency lock should be on. The default setting is

frequency lock on. Frequency lock is disabled when

FM mode is selected. Frequency lock can be turned

off by using a SPCL function. Refer to Special Func

tions in this section of the manual.

Amplitude Modulation

A signal applied to the AM IN connector modulates

the amplitude of the output waveform. Amplitude

NORMAL MODULATION

0.6 V Modulating Signal

modulation effectively multiplies the amplitudes of the

generator and the external signal applied to the AM

IN connector.

A modulating signal of approximately 4.5 volts peak

to-peak will cause 1 GO-percent modulation of the

output if the output amplitude is set to 5 V peak-to

peak; if the output amplitude is greater than 5 V

peak-to-peak, a 4.5 V modulating signal will cause

clipping of the output signal. Refer to Table

1 -1 0,

INPUT, in the Specifications section.

The PFG 5105/5505 output amplifier cuts off at

=::

10.2

volts peak to peak. Any modulation that causes a

peak-to-peak voltage near this limit will distort the

output. The maximum output voltage that can have

100% modulation is 5.1 volts peak to peak.

See Fig 2-7 for an example of how an output of g

volts peak-to-peak is distorted with a 0.8 volt modulat

ing signal but not with a 0.6 volt modulating signal.
To enable amplitude modulation, press the AM key

(LED on).
