MINIMIZING WAVEFORM DISTORTIONS
USE 50 Ω TRANSMISSION LINES
Connect the load to the pulse generator with 50Ω transmission lines (e.g. RG-58 or RG-
174 cable). If possible, use a 50Ω load. If the actual device under test has a high
impedance, consider adding a 50Ω termination in parallel with the load to properly
terminate the transmission line.
USE LOW-INDUCTANCE LOADS
Lenz’s Law predicts that for an inductive voltage spike will be generated when the
current through an inductance changes. Specifically, V
SPIKE
= L × dI
LOAD
/dt, where L is
the inductance, I
LOAD
is the load current change, and t is time. For this reason, it is
important to keep any parasitic in the load low. This means keeping wiring short, and
using low inductance components. In particular, wire-wound resistors should be
avoided.
