Page 9: Product Overview
Product Overview The PBD2000 Differential Probe is a 2-GHz bandwidth, differential-input, active probe that is used in combination with a digital oscilloscope* that has a YOKOGAWA probe interface (hereafter referred as digital oscilloscope with a probe interface). To use the probe, you simply connect it to a BNC input terminal on a digital oscilloscope with a probe interface. -

Component Names Cable Probe head Add various attachments, connect to circuit under test Probe interface To digital oscilloscope input Latch release lever Output terminal Variable resistor for adjusting offset voltage Probe head Cable Interface Probe interface spring pin Attachments L-pins (2) Lead wires (one each in red and black) Microclips Straight pins (8) -
Page 11: Usage Precautions
Component Names Output termina The output terminal is a BNC connector. It connects to an oscilloscope input BNC connector. Variable resistor for adjusting offset voltage You can adjust the offset voltage using an appropriate driver as described below. Adjustment driver Use an adjustment driver that fits into the adjustment groove. -
Page 12: Operating Procedures
Operating Procedures Preparation Have the probe and a digital oscilloscope with a probe interface ready. Insert the probe interface completely into the oscilloscope input, and confirm that the BNC connector and interface pin are securely fastened. You will hear the latch click when the connectors lock into place. Attach any of the provided attachments to the probe head signal input terminals. - Page 13 Example • For signals of relatively low frequency Lead wire Microclips • For signals of relatively high frequency Probe head Select an attachment according to the circuit to be tested (straight pin, angle pin, spring-type straight pin, or spring-type angle pin).

- Page 14 Warm-up and Offset Adjustment Warm-up Immediately after connecting the probe, the heat emitted by the probe itself causes the offset voltage to drift. Warm up the probe for at least 30 minutes after applying power to stabilize the probe. Offset Adjustment You can turn the offset voltage adjustment variable resistor on the probe interface by using an appropriate adjustment driver (see page 3 for details) to adjust the residual offset voltage that remains even after warm-up.

DC and low frequencies. Yokogawa’s standard 10:1 passive probes are easy-to-use for general applications. Their input impedance is 10 MΩ and approximately 14 pF in parallel, and the withstand voltage is 600 V. However, the 14 pF input capacitance might cause problems when high frequencies are measured. - Page 18 Appendix—Probing Active Probes and FET Probes Active and FET probes are those most often used to measure high frequency signals. Unlike passive probes, an impedance-converting buffer amplifier is situated near the tip of the probe which enables them to handle higher frequencies with around 1-pF input capacitance.
- Page 19 Appendix—Probing Problems with Probing High-Speed Signals Loading Effect When a probe is connected to the circuit under test, the input impedance of the probe itself has certain effects on the circuit. This is called the loading effect. There can be cases where there are notable low pass filter effects caused by the signal source impedance and the probe’s load capacitance, particularly when observing frequency components of 100 MHz or more.
- Page 20 Appendix—Probing Changes in Cable Characteristics A coaxial cable is used to transfer signals from the probe tip to the oscilloscope. Cables that can offer the right balance of both flexibility and high frequency performance are selected after considering the ways in which the cables will actually be handled.
