KEYSIGHT 示波器探棒 Probe

Passive Probes

Keysight offers a broad range of passive probes with various attenuation ratios and input impedance specifications to optimize the dynamic range and loading considerations of your oscilloscope ground-reference measurements. These passive probes are compatible with most Keysight oscilloscopes that have either standard BNC inputs or AutoProbe1/BNC input connections.

1. Input impedance when terminated into oscilloscopes with 1-MΩ input terminations. For higher-bandwidth Infiniium oscilloscopes with 50-Ω input terminations only, the E2697A high impedance adapter can be purchased (includes 10073D 500-MHz passive probe) to provide a 1-MΩ input termination. 

2. For proper probe compensation (flatness), the oscilloscope’s input capacitance must be within the specified compensation range of the probe. 

3. Capacitance at the probe tip of 1:1 probes is the specified probe capacitance plus the capacitance of the oscilloscope when terminated into 1-MΩ.

4. Input impedance when terminated into oscilloscopes with 50-Ω input terminations. These probes are not compatible with Keysight’s InfiniiVision 1000 and 2000 X-Series oscilloscopes.
