TCPA300/400 Amplifiers and TCP300/400 Series Current Probes Instruction Manual
The amplifier amplifies the current sensed by the probe and converts the current
to a proportional voltage that is displayed on an oscilloscope or other similar
measuring device.
The following Tektronix current probes are compatible with the TCPA300
Amplifier:
H
TCP312 (30 amps, 100 MHz)
H
TCP305 (50 amps, 50 MHz)
H
TCP303 (150 amps, 15 MHz)
The following Tektronix current probes are compatible with the TCPA400
Amplifier:
H
TCP404XL (750 amps*, 2 MHz)
* 500 amps continuous, 750 amps DC derated with duty cycle
You can also use the CT-4 High-Current Transformer with the TCP305 and
TCP312 current probes to extend the AC current measurement range to
20,000 peak amps.
An oscilloscope displays the output from the current measuring system. A 50
Ω
cable is included to connect the amplifier to the oscilloscope input channel. A
TEKPROBE-to-TEKPROBE interface cable is also included for connecting to
TEKPROBE level II oscilloscopes.
If the oscilloscope does not have an input that can be set to 50
Ω
impedance, you
need a feedthrough 50
Ω
termination. This termination is included as a standard
accessory with your TCPA300 and TCPA400 Current Probe Amplifiers.
