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 Tektronix TDS3000,
TDS500, TDS600, TDS700, TDS5000, TDS6000, and TDS7000B series
oscilloscope systems (the DPO3000, MDO/MSO/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.
