    Figure 9-11: Using of memory curves to see changes in the measurement and to compare different curves You can use multiple memories to determine the change of your DUT depending on a parameter. The following figure shows an example of how the parallel resonance frequency of the quartz filter changes when touching it. OMICRON Lab...

  • Page 120: Using Probes

    Using probes You can use any probe with Bode 100 that offers a standard BNC connector. The use of probes can have the following advantages: • Reduction of the capacitive loading added by connecting Bode 100 to your circuit. •...
  • Page 121 To configure the probe factor, you can use the combo-box. Click on the arrow and select one of the pre-defined probe factors: Alternatively you can enter an arbitrary probe factor by marking the text and entering your probe ratio as shown in the examples below: OMICRON Lab...

    10 Automation interface Besides the Bode Analyzer Suite, Bode 100 can also be controlled via the Automation Interface, a software command interface. The Automation Interface can either be accessed via the COM interface or directly from .NET. Furthermore, a LabVIEW instrument driver is available to control Bode 100.
  • Page 127: Troubleshooting

    Check if the USB cable is properly plugged into the computer and the Bode 100. b. Try disconnecting and re-connecting the USB cable. c. If this does not help, avoid USB hubs and plug Bode 100 directly into an USB port of your computer.
