  • Page 11: Product Overview

    Product Overview The PBDH1000 Differential Probe is a 1-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.

  • Page 12: Component Names

    Component Names Cable Probe head Add various attachments, connect to circuit under test Probe interface To digital oscilloscope input Latch release lever Variable resistor for adjusting offset voltage Output terminal Probe head Cable Interface spring pin Probe interface Connects to a digital oscilloscope input. Interface spring pins When the probe output terminal is connected, these pins touch the pad on the oscilloscope interface board.

    If you are connecting the probe to a DL9000 Series digital oscilloscope with software version earlier than 4.05, manually configure the following settings after you connect it.For information on how to update the DL9000 Series software, contact your nearest YOKOGAWA dealer. • Set the probe attenuation ratio to 50:1. • Set the input coupling to 50 Ω.
  • Page 14 Operating Procedures Attachment Handling Connect attachments that are suitable for the item that you want to measure to the signal input terminals illustrated below. Select attachments from the following list (see page 9 for attachment application examples). • 5-cm pair lead Can connect directly to a pin header or the item you want to measure.
  • Page 15 Operating Procedures Creating an Extension Lead You can create your own extension lead using the accessory kit. At the Circuit-under-Test End Pass the lead wire through a heat-shrink tube for a contact. Crimp or solder the lead wire’s core wire to the contact. Cover the contact with the heat-shrink tube, and then apply heat with a drier to fix the tube in place.
  • Page 16 Operating Procedures Probe-Head End Pass the lead wire through the heat-shrink tube. * The heat-shrink tube for the probe-head end is not included. It must be obtained separately. Solder the lead wire’s core wire to the flanged input pin. Cover the flanged input pin with a heat-shrink tube, and then apply heat with a drier to fix the tube in place.
  • Page 17 Operating Procedures Attaching the Retaining Cover Pass the flanged sections of the two input pins through the center retaining-cover holes, and place the input pins on the holders on either side. Flange Align the + and − markings on the retaining cover to those on the probe head, and attach the retaining cover to the probe head. Check that the retaining cover’s left and right latches are securely locked.
  • Page 18 Operating Procedures How to Use the Ground Extension Lead Example Ground terminal Ground extension lead Connecting the probe ground terminal to the common ground on the circuit under test using the ground extension lead may reduce noise when measuring low-frequency signals. CAUTION Only connect the ground extension lead to the common ground.

  • Page 20 Operating Procedures 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 2 for details) to...
