Slope - Segment
Trigger
Selects the slope of the active edge of the external trigger signal. The
slope can only be set for an external trigger signal that is fed in via the
NEXT connector on the rear panel.
Positive
The rising edge is selected.
Remote-control command:
SOUR:INP:TRIG:SEGM:SLOP POS
Negative
The falling edge is selected.
Remote-control command:
SOUR:INP:TRIG:SEGM:SLOP NEG
The
Control Line Setup
section is where the threshold and impedance of the trigger inputs CLOCK IN
/ TRIG / NEXT are selected.
Threshold - Trigger
Sets the high/low threshold for the inputs CLOCK IN, TRIG and NEXT.
A threshold can only be set with an external trigger source.
Remote-control command:
SOUR:INP:CONT:THR
Impedance - Trigger
Sets the impedance value for the inputs CLOCK IN, TRIG and NEXT.
The lower value, 50 Ohm, is recommended for high clock frequencies
or signals with high slew rates. The impedance is set for external
trigger signals.
Remote-control command:
SOUR:INP:CONT:IMP
The
Waveform Diagram
section indicates the graph for the selected waveform type.
Waveform Diagram -
Trigger
Displays schematically the graph of the currently loaded waveform,
either as standard sine waveform or as multi segment waveform. After
the instrument switch on, the graph of the last loaded waveform is
displayed.
Note:
The curves plotted in this dialog box only are textbook examples,
not measured
waveforms. They are intended to visualize the
trigger settings more clearly.
Shown for
standard
waveforms
The graph shows the generation of the waveform
depending on the selected trigger configuration.
This section is shown only if a standard
waveform is loaded.
Shown for
segmented
waveforms
The graph shows the generation of the waveform
depending on the selected trigger and segment
trigger configuration. This section is shown only if
a multi segment waveform is loaded.
