Atec Tektronix-TDS744A User Manual
Power-electronics measurement system

he Power Electronics
Measurement System
provides a breakthrough in
measurement capability for
designers who make many
types of power, current,
and floating voltage
measurements.
The system consists of a
TDS 744A oscilloscope*,
P5205 high-voltage
differential probe, and the
TCP202 current probe.
The probes are powered by
the scope via the TEKPROBE
™
interface and the readout
on the screen is in Volts,
Amps, or W (watts) with
correct magnitude.
