Table 6 DisplayPort Calibration Parameters
Parameter name Parameter Description
Calibration
Oscilloscope
Bandwidth Bandwidth of the oscilloscope in use.
Acquisition Time The acquisition time for each captured data signal.
Decreasing this value might speed up the calibration but
reduces accuracy.
Measured ISI with
histogram Uses Histogram instead of EZJIT+ oscilloscope software
for ISI measurement.
Memory Depth Number of acquired points used by the scope to measure
jitter.
Measurement Cycles Number of averaged measurements for each calibration
step. Decreasing this value might speed up the calibration
but reduces accuracy.
Jitter
Use Explicit Clock Jitter is measured with explicit clock, otherwise, with
Constant Clock.
ISI Amplitude ISI amplitude that is applied.
First Variable ISI Value First Variable ISI value set to the Artek CLE1000-A2.
Stop Jitter The maximum calibrated random jitter (RJ) amplitude.
Jitter Step Count The number of jitter calibrated steps.
SJ Frequency Sinusoidal jitter (SJ) frequency used to apply the jitter
values.
Pattern
Sequence File Specifies the name of the sequence file that should be
used.
Aggressor Clock
Divider The clock divider for the aggressor lane pattern.
Pattern Period Length Period length of the pattern; this information is required
for jitter measurements. It should be changed only when
using a custom pattern.
Pattern Period Length
Auto Detect Automatically determined period length of the pattern.
