TCA VPI50 51W276352

Expand the functionality of Tektronix high-performance oscilloscopes

The TCA-VPI50 adapter extends the functionality of the TCA Series of adapters by enabling 50 Ω TekVPI probes to be used on oscilloscopes with TekConnect interfaces. The TekVPI interface is used on bench and performance oscilloscopes from 100 MHz up to 3.5 GHz, and until now, TekVPI probes could only be used on oscilloscopes that have a TekVPI Probe Interface. The TCA-VPI50 will only work with 50 Ω terminated probes. It will not work with 1 MΩ terminated probes, examples of which are passive probes, current probes, and most high-voltage probes.
