MINIMIZING WAVEFORM DISTORTIONS
USE 50 OHM TRANSMISSION LINES AND LOADS
Connect the load to the pulse generator with 50Ω transmission lines (e.g. RG-58 or
RG-174 cable).
This instrument requires a 50Ω load for proper operation. It will not properly drive a
high-impedance load.
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.
