Menu Item Function
(Type) Selections (SCPI cmd)
Position
Pulse  Positions the trigger within the waveform display window.
(Multiple Choice) L, M, R
Press the Time > Position menu key to shift the start of the waveform
display to the left edge (―L‖), middle (―M‖) or right edge (―R‖) of the
display area. Use this function to view a specific segment of the
waveform. Select ―L‖ to observe the waveform immediately after the
trigger occurs; ―R‖ to observe the waveform immediately before;
and ―M‖ to observe segments of the waveform just before and after
the trigger.
TRIGger:POSition {LEFT, MIDDLE, RIGHT}
Trig Delay
Pulse Sets the amount of delay between the trigger and
(Numeric) Continuous Range: the start of sweep.
(See discussion)
The trigger delay is a time offset from the trigger event to the point at
which the waveform data is captured. Adjust the trigger delay using
any of the data entry controls.
The Model 4500B automatically adjusts the limits of the Time >Trig
Delay parameter range not to exceed the limits established by the
Time > Timebase selection. Trigger Delay Limits are listed in the
instrument‘s specifications, Table 1-2.
TRIGger:DELay <arg>. See Table 1-2 for argument range.
Fast Trigger Pulse Press the Time > Fast Trigger menu key to turn the Fast Trigger
(Toggle) Off, On function on or off. The Fast Trigger operates only for mid-timebases
(500 us/Div to 2 us/Div) and minimizes trigger arming delay. Used to
speed the formation of persistence type displays, e.g. eye diagrams.
Normally off.
