Increased Performance and Simplicity

The TCP300 and TCP400 series AC/DC Current
Measurement family is a highly advanced
current measurement system for today’s
current measurement needs.The split-core
probes incorporate both transformer and Hall
effect technology to provide broad bandwidth
measurement capabilities from DC up to
100 MHz at current levels as low as 1 milliamp
to thousands of amps (when used with CT4
current transformer). When connected to
Tektronix TDS Oscilloscopes with TEKPROBE
Level II or TekConnect (w/TCA-BNC) interfaces,
current measurements and calculations are
simple and easy.

Additional measurement power is available
with add-on software such as the TDSPWR2
power measurements package.With all this
measurement power current measurements
have never been easier.

Meets Today’s AC/DC Current
Measurement Applications

The TCPA300 amplifier, when used with
TCP312,TCP305,or TCP303 probes,provide a
wide range of current measurement capability
and spans the gap between low level milliamp
measurements to very high current levels.
These three probes provide current measure­ment capabilities of 30A, 50A, and 150A DC
continuous. For even higher current levels, the
TCPA400 amplifier with the TCP404XL current
probe measures 500A DC continuous and
750A DC continuous, derated with duty cycle.

Higher frequency performance is available with
the TCP312 w/TCPA300 providing ≥100 MHz
bandwidth and a maximum current of 30A DC.

Measurement Errors and
Manual Calculations Are
Now a Thing of the Past

With this new series of current measurement
tools, automatic control and on-screen
scaling and units is provided for users of
T ektronix TDS3000,TDS400A, TDS500,TDS600,
TDS700, TDS5000, TDS6000 and TDS7000
series oscilloscope systems.

Status LEDs quickly show you TCP300/400
series operating status or potential error con­ditions that may have caused measurement
errors in the past.

The TCP300 / TCP400 Current Measurement
Systems seamlessly integrate with your TDS
series oscilloscope and the TDSPWR2 software

package to easily make those time consuming
power measurements and calculations for you.

Even non-TEKPROBE systems can use the
TCPA 300/400 series to make proper current
measurements by simply multiplying the
measured output voltage on the oscilloscope
by the TCPA 300/400 series range setting.
