Shunt Settings: Low-Side

  • Source Shunt Value: Enter value, in Ohms, of the Low-Side Coaxial Shunt Resistor. This value is printed on the shunt label. The default/nominal value for the Keysight PD1000-61901 Shunt is 0.05 W. For the PD1550-61902 shunt, the default/nominal value is 0.005 W.

  • Use High-Z Input (checkbox): Leave the box unchecked when using the Coaxial Current Shunt with the PD1000-60002 Oscilloscope Protection Probe. Check the box if you are not using the PD1000-60002 Oscilloscope Protection Probe and the top of the Coaxial Shunt connects directly to the oscilloscope (High Z input).

  • De-embedding File Name: Enter the de-embedding file name. For example, MY584xxxx.tf2 (where “xxxx” is the shunt’s serial number). The file should be installed in the DSOS104A oscilloscope in the folder: C:\Users\Public\Public Documents\Infiniium\Filters.

On the oscilloscope, the file path will show as:
C:\Users\Public\Public Documents\Infiniium\Filters. However, this is an alias path. Use the path: C:\Users\Public\Documents\Infiniium\Filters in the Shunt Settings De-embedding File path in the Control Software.

Temperature Control Settings

  • Heater Unit: Select either None (default) or Hotplate from the drop-down menu. Note that the InTEST Hotplate is not a Keysight products and must be ordered from InTESTa. See “Using the InTEST Heater” for more information about using the InTEST (Watlow) EZ-ZONE controller and hotplate.

  • Temperature Reference Measure Device: Select None (default). The temperature is not displayed in the 2023-324 version of PD1000A software.

  • Tolerance: Specify a range (±) around the specified temperature for triggering the DPT measurement. For example, if you specify making a DPT measurement at 100 °C and a 2 °C Tolerance, then the measurement triggers somewhere between 98 °C and 102 °C.

  • Settling Time: Specify a time period (in seconds) to wait after the DUT reaches the specified temperature (withing the specified range) before triggering the DPT measurement.

  • Temperature Control Timeout: Specify the maximum time period (in seconds) to wait for the device to reach the specified temperature before triggering the measurement. If the device does not reach the specified temperature within this time period, the DPT test aborts.

For example, to go from ambient temperature (~25 °C) to 100 °C with a 2 °C Tolerance may take a few minutes due to the thermal mass of the DUT and heater plate.
