Modulating Source
The waveform generator will accept an internal or external modulation
source for Sum.
• Modulating source: Internal (default), Other Channel, or External.
• If you select the External source, the carrier waveform is summed with
an external waveform. The amplitude is controlled by the ±5 V signal
level present on the rear-panel Modulation In connector. For example,
if you have set the sum amplitude to 10%, then when the modulating
signal is at +5 V, the output will be at the maximum amplitude (110%
of carrier amplitude). When the modulating signal is at -5 volts, the
output will be at the minimum amplitude (90% of Carrier amplitude).
• Front-Panel Operation : After enabling Sum, press the
