Parameter Description Definition Notes
Period@level Period at a specified level and
slope for every cycle in waveform.
Reference levels and edge-
transition polarity can be
selected. Hysteresis argument
used to discriminate levels
from noise in data.
Available with JTA2, AORM,
ENET, SDA, and XMAP
options.
Standard in DDA-5005A,
SDA100G, and WavePro
7000A scopes.
Per Pulse Sym Symmetry of RZ pulse around eye
aperture center
Standard in SDA and
WaveExpert scopes.
Persist Area Area under mean persistence trace Standard in SDA and
WaveExpert scopes.
Persist Max Highest vertical value of input
persistence
Standard in SDA and
WaveExpert scopes.
Persist Mean Average of persistence data Standard in SDA and
WaveExpert scopes.
Persist Mid Mid level between Maximum and
Minimum data
Standard in SDA and
WaveExpert scopes.
Persist Min Lowest vertical value of input
persistence
Standard in SDA and
WaveExpert scopes.
Persist PkPk Difference between maximum and
minimum data values
Standard in SDA and
WaveExpert scopes.
Persist RMS Root mean square of persistence
data
Standard in SDA and
WaveExpert scopes.
Phase Phase difference between signal
analyzed and signal used as
reference. You can set the output
type to percent, degrees, or
radians. After setting up the
reference, touch the More tab for
signal setups.
Phase difference
between signal and
reference
Standard parameter.
Pj Periodic component of jitter Available with SDA option.
Power Factor Ratio of real to apparent power Available with PMA2 option.
PW50 Average pulse width at the 50%
point between the local baseline
and the local peak or trough.
Hysteresis argument used to
discriminate levels from noise
in data.
Available with DDM2 option.
Standard in DDA-5005A.
PW50- Average pulse width at the 50%
point between the local baseline
and the local trough.
