Increased Performance and Simplicity
The TCP30
is a highly advanced current measurement system for today's current
measurement needs. When connected to Tektronix oscilloscopes with
TEKPROBE Level II, TekConnect (w/ TCA-BNC), or TekVPI (w/ TPA-BNC)
interfaces, current measurements and calculations are simple and easy.

Meets Today's AC/DC Current Measurement
Applications
The TCPA300 amplifier, when used w ith TCP312, TCP305, or TCP303
probes, provi
des 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
30 A, 50 A, and 150 A DC continuous. For even higher current levels, the
TCPA400 amplifier with the TCP404XL current probe measures 500 A D C
continuous and 750 A 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 30 A DC.
Measurement Errors and Manual Calculations are Now
a Thing of the Pa
st
With this new series of current measurement tools, automatic control and
on-screen sca
ling and units is provided for users of Tektronix TDS3000,
TDS500, T DS600 , TDS700, TDS5000, TDS6000, and TDS7000B Series
oscilloscope systems (the DPO3000, DPO4000, and DPO7000 Series
oscilloscopes, the TPA-BNC adapter is required).
The TCP300/TCP400 current measurement systems seamlessly integrate
with your TDS Series oscilloscope.
Even non-TEKPROBE systems can use the TCPA300/400 Series to make
proper current me asurements by simply multiplying the measured output
voltage on the oscilloscope by the TCPA300/400 Series range setting.
