Page 11: Operating Basics
Operating Basics To get guaranteed performance from the P5102 probe, please read and apply the information in this section. Observe Voltage Derating Information WARNING. To avoid personal injury, do not handle the probe when the common lead is connected to a source that is above the voltage and frequency limits given in Figure 11b on page 18. -
Page 12: Probe Loading
Refer to Figure 12 on page 19 for a graph of frequency versus input impedance. The probe has virtually no loading effect on sources with relatively low impedance and low frequency. P5102 Instructions... -
Page 13: Adjustment Procedures
Adjustment Procedures The low-frequency (LF) compensation of the P5102 probe must be checked every time the probe is connected to a different oscilloscope input. The high-frequency (HF) compensation should be checked if the probe was repaired or fails to meet rated bandwidth specifications. -
