Keysight 81160A - Modulating Waveform Shape

Appendix

3.11.4 Modulating Waveform Shape
Introduction
The 81150A / 81160A will accept modulation from an internal or external
modulation source. In case of internal modulation, the modulation signal can
be the ‘other channel’ (2 channel instrument only) or the internal modulation
source of the modulated channel.
Characteristics
 Modulating waveform shape (internal source): Sine, Square, Ramp,
Negative Ramp, Triangle, Noise, or Arb waveform. The default is
Sine.
 Square has 50% duty cycle
 Ramp has 100% symmetry
 Triangle has 50% symmetry
 Negative ramp has 0% symmetry
 If you select an arbitrary waveform as the modulating waveshape, the
waveform is automatically limited to 16K points. Extra waveform
points are removed using decimation.
