Step 5 - Configure the Probe Settings in the Oscilloscope Software GUI
After making hardware connections, perform the following steps in the
Infiniium / InfiniiVision
Oscilloscope software GUI
to configure probe settings such as identifying the type of probe attached
to the oscilloscope and setting the appropriate input impedance and attenuation ratio etc. These
settings are required to get accurate measurement results.
On an Infiniium Oscilloscope
1 Choose
Setup
>
Probe Configuration...
to open the
Probe Configuration
dialog box. The
N7040A/41A/42A probe is not automatically identified by the oscilloscope and therefore not
displayed as connected to the scope’s channel.
2 To manually identify the type of probe and configure its settings, click
Options...
displayed in the
Probe System
section of the scope channel to which the current probe is connected. In the above
screen, the settings for the N7042A probe connected to Channel 1 are being configured.
3 The
Probe
dialog box is displayed. Select the
Current Probe attached
option from the
Probe Type
drop-down listbox.
4 From the
Current Probe
drop-down listbox, select the attenuation ratio for your current probe to
match the Output/Input ratio (in V/A) (printed on the label on the front side of the probe).
