Sum Modulation (Sum)
3
Modulating Waveform Shape
The waveform generator will accept an internal or external modulation
source for Sum.
• Modulating waveform shape (internal source): Sine (default), Square,
Pulse, UpRamp,
DnRamp, Triangle, Noise, PRBS, or Arb waveform
.
• Square has 50% duty cycle
• UpRamp has 100% symmetry
• Triangle has 50% symmetry
• DnRamp has 0% symmetry
• PRBS uses PN7 sequence.
• Front-Panel Operation: After enabling Sum, press the Shape softkey.
• Remote Interface Operation:
SUM:INTernal:FUNCtion
{SINusoid|SQUare|PULSe|RAMP|NRAMp|TRIangle|
NOISe|PRBS}
Modulating Waveform Frequency
The waveform generator will accept an internal or external modulation
source for Sum.
• Modulating frequency (internal source): 1 Hz to 30 MHz.
The default is 100 Hz
.
•
Front-Panel Operation
: After enabling Sum, press the
Sum Freq
softkey.
• Remote Interface Operation:
[SOURce[1|2]:]SUM:INTernal:FREQuency
{<frequency>|MINimum|MAXimum}
