Differential Probes

TDP1500 and TDP3500 Datasheet

Differential active probes provide truer signal reproduction and fidelity for

high-frequency measurements. With ultra-low input capacitance and

versatile device-under-test connection capabilities, the TDP1500 and

TDP3500 Differential-ended Active probes provide excellent high-speed

electrical and mechanical performance required for today's digital system

designs.
