CALCulate<Chn>:EYE:MEASurement:TTIMe:THReshold
<ThresholdEnum|
LowerThreshold>[, <UpperThreshold>]
Defines the lower and upper threshold that are used to calculate the transition times
(rise/fall time) in an eye measurement.
The thresholds can either be specified by enum constants for the standard 10–90% or
20–80% rise times, or numerically.
Suffix:
<Chn>
.
Channel number used to identify the active trace
Parameters:
<ThresholdEnum|LowerThreshold>
T1_9: 10–90% rise time
T2_8: 20–80% rise time
<integer>: Lower rise time threshold as integer percentage
*RST:
T1_9:
<UpperThreshold>
Upper rise time threshold as integer percentage

Manual operation:
See
CALCulate<Chn>:EYE:NOISe:RMS
<NoiseRMS>
Defines the root mean square (RMS) noise level in the generator simulation of the rela-
ted eye diagram.
This command will raise an execution error if the active trace in the selected channel is
not an eye diagram.
Gaussion noise insertion can be enabled using
.
Suffix:
<Chn>
.
Channel number used to identify the active trace
Parameters:
<NoiseRMS>
Default unit: V
Manual operation:
See
CALCulate<Chn>:EYE:NOISe:STATe
<Boolean>
Enables/disables Gaussian noise in the generator simulation of the related eye dia-
gram.
This command will raise an execution error if the active trace in the selected channel is
not an eye diagram.
The noise RMS level can be set using
.
