DPO4000, MSO/DPO5000, 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 measurements by simply multiplying the measured

output voltage on the oscilloscope by the TCPA300/400 series range

setting.
