4. Enable Channel 1 and/or Enable Channel 2. The loaded .kaf file consists of a waveform for
one or both of the channels. If the .kaf file was saved with one or both channels enabled,
the .kaf file loads into this tab with the same channels enabled. A channel must be enabled in
order to preview and output its waveform. The waveform for Channel 1 is blue and the waveform
for Channel 2 is red.
5. Configure triggers for both channels of the pulse card:
Trigger Source - Software, External, or Internal Bus. With External enabled, select the
trigger source: Initial Falling, Initial Rising, Per Pulse Falling, or Per Pulse Rising.
Output Mode - Select the output trigger mode: Continuous Mode or Burst Mode.
6. Configure the Channel 1 Settings and/or Channel 2 Settings. The Pulse Count field is active if
the Burst Mode is the selected trigger mode.
To configure other installed pulse cards for Custom File Arb, repeat steps 1 through 6.
7. Select the green triangle to turn on enabled channels for all installed pulse cards in the
4200A-SCS. With the output on, the square box turns red. To turn off the outputs of all pulse
cards, select the red box.
Waveform types
KPulse provides the following fundamental waveform types to use as the building blocks for custom
file arb:
• Sine waveform (on page 5-14)
• Square waveform (on page 5-14)
• Triangle waveform (on page 5-15)
• Custom waveform (on page 5-15)
• Calculation waveform (on page 5-17)
• Noise waveform (on page 5-17)
• Gaussian waveform (on page 5-18)
• Ramp waveform (on page 5-19)
• Sequences waveform (on page 5-20)
As explained in Custom Arb file operation: Select and configure waveforms (on page 5-10), a
waveform is created using the Waveform Generator. After selecting and configuring one of the above
waveform types, the waveform is placed into the Scratch Pad.
The period for the waveforms is determined by the Time Per Point setting in the Arb Generator tab
(refer to Custom Arb file operation: Copy waveforms into Sequencer (on page 5-11
)).
