Using Probes - Omicron Lab Bode 100 User Manual

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.
• Easier probing possibilities when no BNC connectors are available on the DUT.
• Protection of Bode 100 from hazardous voltages if safety isolation probes are used.
WARNING
Check safety instructions
hazardous voltages >50 VDC or >25 VAC.
NOTICE
Bode 100 inputs are AC coupled with a maximum allowed DC voltage of 50 VDC. A standard,
passive, 10:1 probe with 9 MΩ tip-resistor cannot be used to connect Bode 100 to higher DC
voltages! The DC-voltage will not be divided by 10 can destroy the AC coupling capacitor and
damage the input circuitry!
If a probe has a different probe factor than 1:1, you can configure the probe factor in the hardware
setup dialog for each channel separately. To do so, enter the hardware setup dialog by clicking on the
hardware setup icon in the home ribbon
The following figure shows the hardware setup dialog for a Gain / Phase measurement where two
external probes (Probe 1 and Probe 2) can be configured.
