Parameter Description
It is a DUT attribute that determines the minimum PREPARE time supported. It has a permitted range from 0 to
15.
It is the distance between DIFN pulses. If only one pulse is applied, it gives the distance between the following
DIFP (Positive Differential Voltage) state next to the DIFN state.
It is the width of the DIFN pulse. It's default value is 20 ns.
It is the data rate for the PWM mode.
It is the PWM Receive Ration provided for the test.
It can be adjusted as "NominalRefClock" and "NominalDataRate".
It is the frequency value of the reference clock.
It is the step size value of the reference clock skew during the Jitter Tolerance test.
It is the step duration value of the reference clock skew during the Jitter Tolerance test.
If the value is set to True, the test sequence starts again from the beginning every time the DUT is reset.
It is the amplitude value of the RJ added to the test signal during calibration.
During RJ calibrations, the oscilloscope adds an additional amount of jitter. This jitter can be calculated by
the scope using EZJit Wizard. If that calculated value is set to the "Scope RJrms" parameter, it will be
subtracted from the RJ measurement.
This property is used for HS, PWM and SYS Termination tests. If false, the software automatically measures the
termination time. If true, the automation finds the spot where the burst starts but lets you place the markers
manually. Then, with the position of the markers, the termination time is calculated. This is useful in cases
where the software is unable to calculate this time automatically because of, for example, reflections in the
signal that impair the algorithm.
It is the sequence file used during the test to the DUT.
It is the signal offset set for the data channel.
It is the single ended amplitude value set for the data channel.
It is the short term deterministic jitter amplitude value.
It is the amount of short term random jitter amplitude added to the signal.
It is the short term total jitter amplitude value.
It can be selected as "True"/"False" to switch between real time eye and single waveform. The measurement
time increases by viewing the real time eye.
It is the provided sleep length value (it is the power saving state between LS Bursts).
