Selecting the right probe for the application is the key to obtain the best signal fidelity in measurement. Active probe provides more real signal replication and fidelity for high frequency measurement. The TAP2500 and TAP3500 single-ended active FET probes provide the superior high-speed electrical and mechanical properties required for today's digital system designs through ultra-low input capacitors and unique interfaces.
TAP2500 and TAP3500 active FET probe specially designed, can be used and connected directly to the with TekVPI ™ oscilloscope probe interface, by solving the problem of the following three traditional fidelity of high-speed signal acquisition and measurement:
By 0.8 pF input capacitance and 40 k or less loading ? input impedance to reduce the DUT
Connect to a small SMD using a multifunctional DUT connection
The instrument bandwidth is reserved for an oscilloscope up to 3.5ghz at the end of the probe
