TCPA300 and TCPA400
Current Probe Amplifiers
The amplifier am
plifies 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.
Current P robes
The followin
g Tektronix current probes are compatible with the
TCPA300 Amplifier:
TCP312 (30 A
, 100 MHz)
TCP305 (50 A, 50 MHz)
TCP303 (150 A, 15 MHz)
The following Tektronix current probes are compatible with the
TCPA400 Amplifier:
TCP404XL (750 A
1
,2MHz)
1
500 A continuous, 7 50 A 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
peakA.
Oscilloscope
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.
