Electrical Sampling Modules
For example: if Max = –989 m
ρ
and Min = –1.003
ρ
,
positive aberration (%) = (1000 + (–989)) * 0.1 = +1.1
negative aberration (%) = (1000 + (–1003)) * 0.1 = –0.3
4.
Repeat the Setup and Test procedures for the TDR negative edge polarity. To
do this check, select negative edge polarity after selecting TDR Preset in
Setup step 4 a under
TDR-System Step Response Aberrations (80E04)
. No
other changes to the procedures are needed, since in rho (
ρ
) mode the display
does not invert when the TDR edge polarity is changed.
5.
Repeat the Setup and Test procedures for channel 2, both polarities.
End of Procedure
TDR-System Step Response Aberrations (80E08B and 80E10B)
These procedures check those characteristics that relate to the TDR system and are
listed as checked in the
DSA8300 Digital Serial Analyzer Speci
fi
cations
manual.
Equipment required
