Procedure Parameters are parameters that do not fall into one of the
previously described categories. They are shown on the right side of the
N5990A user interface when the selected entry of the procedure tree on
the left is an individual procedure. They only change the behavior of that
single procedure. Procedures often have parameters with the same name,
but set settings always apply on the selected procedure, and the meaning
may be slightly different. These parameters are listed in
Table 6 Procedure Parameters
Parameter Description
It is the accumulated voltage set in the data generator to get the desired Eye Opening.
These are additional jitter frequency points beside the frequency range, where the actual jitter amplitude is
measured.
These are additional steps to be performed for the test.
It is the differential voltage amplitude of the tested/calibrated data signal.
It is the range of the amplitude values to be tested. It is defined with four values separated by semicolons:
<Start Value>;<End Value>;<Number of Steps>;<Scale Type>. The scale type can be Linear or Logarithmic.
It exists for Low Frequency RJ Calibration and it can be selected as "Spectral" or "Tailfit". Refer to the Scope
manual for more details as it is related to the EZJit Plus software.
The target BER used in the calibration/procedure.
It can be "True"/"False". If "True", the selected BER reader is used to verify that the DUT is in loopback mode
and transmitting the test pattern properly.
It is the range of the common-mode interface values to be tested over the jitter frequency range. They must be
separated by semicolons.
It is the common mode interference frequency value.
These are the common mode voltage levels to be tested.
It displays the custom data rates added by the user, using the "Custom HS DR" button (see
It is the data rate for the selected GEAR.
It is the deviation value of the data rate across the nominal value.
It is the deterministic jitter amplitude value.
It is the first and maximum differential voltage to be calibrated.
It is the eye width to be calibrated.
