The Teledyne Lecroy ZS2500 is a 2.5 GHZ, .9pF, 1 MOhm Active Voltage Probe.
ZS Series Probes
The high 1 MΩ input resistance and low 0.9 pF input capacitance means this probe is ideal for all frequencies. The ZS Series probes provide full system bandwidth with all LeCroy oscilloscopes with bandwidths of 2 GHz and lower.
The ZS2500 is ideal for 2 GHz Oscilloscopes.
