:FEED
[SOURce:]MARKer:FEED <source> selects the source for the front panel
Marker Out” BNC. The available sources are:
ARM[:STARt|:SEQuence[1]][:LAYer[1]]”: For arbitrary waveforms, the marker
level changes with the first waveform point of the first repetition. A marker pulse is
then output with the next-to-last waveform point of each repetition. For sine waves ,
the marker is a 50% duty cycle square wave at the sine wave frequency.
ARM[:STARt|:SEQuence[1]]:LAYer2”: Once a start arm is received, the
marker is asserted when the first amplitude point is triggered. The marker is
unasserted with the last amplitude point of the last waveform repetition, or
following an
ABORt.
[SOURce:]FREQuency[1]:CHANge”: Outputs a one sample period wide
marker pulse that is output after a frequency change occurs. This shows that the
new steady state frequency has been reached.
[SOURce:]LIST[1]”: Outputs marker pulses specified by the
[SOURce:]LIST[1][:SEGMent]:MARKer and SSEQuence:MARKer commands.
The pulse is normally one sample period wide, but may be widened by placing
markers on consecutive output points. This source is only useful with
[SOURce:]FUNCtion:SHAPe USER (i.e., arbitrary waveform output).
[SOURce:]PM:DEViation:CHANge”: Outputs a one sample period wide
marker pulse that is output after a phase change occurs. This shows that the new
phase has been reached.
[SOURce:]ROSCillator”: The reference oscillator as selected by
[SOURce:]ROSCillator:SOURce.
TRIGger[:STARt|:SEQuence[1]]”: Outputs a nominal 12 nS marker pulse for
each point of the segment list.
