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.
