CFG280 User Manual 9
Reference
This section describes several advanced functions of the CFG280
Function Generator. The variety of swept and modulated signals
available from the function generator make it especially useful for
such applications as testing servo-system or amplifier response,
distortion, and stability. It can be used for FM generation, frequency
multiplication, or as a variable, beat-frequency oscillator. It can be
used to generate repetition rates or tone bursts. The square wave sync
and sweep outputs can be used as a source for TTL logic or to
synchronize an external device,such as an oscilloscope. The CFG280
Function Generator is also useful as a source for amplitude
modulated signals for various purposes.

TTL Signals

To generate a TTL signal, follow these steps:
1. Connect the SYNC OUT connector on the CFG280 Function
Generator to the input BNC connector on an oscilloscope (see
Figure 4) .

2. Observe the results on the oscilloscope. If necessary, change the
volts per division setting or other controls on the oscilloscope to
acquire a useful signal.
