2. Push the sine wave FUNCTION button.
3. Set the FREQUENCY dial to the desired carrier frequency.
CAUTION. To avoid damage to theCFG280 Function Generator,
ensure that the maximum voltage into the rear panel VCF INPUT is
no more than 5 V

.
4. Connect an external voltage signal to the EXT AM INPUT on
the rear panel of the instrument (see Figure 7).
5. Control the amplitude modulation by varying the voltage level of
the external voltage source.
Tone-Burst Generation and
Stepped Frequency Multiplication
You can use the CFG280 Function Generator as a tone-burst
generator or frequency multiplier for checking tone-controlled
devices. This application requires another function generator (such as
the Tektronix CFG253) to serve as a gating signal source and a ramp
generator to serve as a VCF signal source.
1. Connect the MAIN OUT connector on the CFG280 Function
Generator to the oscilloscope input connector (see Figure 8).
2. Connect the ramp generator output to the VCF INPUT connector
on the rear of the CFG280 Function Generator (see Figure 8).
