Arguments
NR3
is the value of the trigger level in volts.
Examples
TRIGGER:LEVEL 1.0E-1
sets the trigger level to 100 mV.
TRIGGER:LEVEL?
might return
TRIGGER:LEVEL 0.24100000000
, indicating
that the trigger level is set to 241 mV.
TRIGger:MODe
This command sets or queries the trigger mode. This is equivalent to selecting a
mode in the Mode section of the Trigger Setup dialog box. These modes apply
only when the Trigger Source is set to Clock/Prescale, C1 clock recovery or C3
clock recovery.
Select Eye Mode if the signal you are acquiring is synchronous with the selected
clock source and you wish to display the acquired data as an "eye diagram"
overlaying all of the acquired data bits with minimal clock to data jitter.
Select Pattern mode if the signal you are acquiring is synchronous with the
selected clock source and you wish to display the individual bits as a "bit stream",
with minimal clock to data jitter.
NOTE.
Pattern mode is only available if the DSA8300 has the ADVTRIG option
present.
Select Other mode if the signal you are acquiring is synchronous with the selected
clock source and you wish to display the acquired data showing the effects of any
clock modulation (such as Spread Spectrum Clocking).
