Precautions to Be Taken When Using Voltage Probes Other Than Those
Provided with the Instrument
• When measuring a signal including a frequency close to 500 MHz, use a probe with a
frequency range above 500 MHz.
• Measurement will only be correct if the attenuation ratio is set
properly. Check the
attenuation ration of the probe that you are using and set it properly
.
Setting the Probe Attenuation Ratio or Voltage-Current Conversion Factor
When using a probe not supported by the probe interface connector, follow the procedure
described in Section 6.6 to set the DL9000 attenuation ratio or voltage-current conversion
factor to match the probe attenuation ratio or voltage-current conversion factor. If this
setting is not carried out, correct measurement values will not be displayed.
Connecting a Probe Supported by the Probe Interface Connector
• If you connect a probe* supported by the probe interface connector to the DL9000, If you connect a probe* supported by the probe interface connector to the DL9000,If you connect a probe* supported by the probe interface connector to the DL9000,
the probe type is automatically recognized, and the attenuation ratio set. Power is
supplied to the probe through the probe interface, and therefore it is not necessary to
connect the probe power cable to the probe power terminals.
• Y
ou can execute automatic zero adjustment (see section 5.14) on a current probe that
is compatible with the probe interface connector.
* For a list of compatible probes, see “Optional Accessories” on page v.
Connecting FET Probe, Current Probe, Differential Probe, or Deskew Correction
Signal Source
If you are using the YOKOGAWA’s FET Probes, Current Probes, Differential Probes, or
Deskew Correction Signal Source, use the Probe Power (option) on the DL9000 rear
panel for the power supply. For details on the connection procedure, see the manual that
comes with the respective product.
* For a list of probes and signal sources, see “Optional Accessories” on page v.
CAUTION
Do not use the Probe Power Terminal (option) on the DL9000 rear panel for
purposes other than supplying power to the FET Probe, Current Probe, Differential
Probe, or Deskew Correction Signal Source. Also, be sure that the total current of
the four Probe Power Terminals and the four Probe Interface Terminals does not
exceed 1.2 A. Otherwise, the device connected to the Probe Power Terminals or to
the DL9000 may break.
