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.
Figure 9-8: Probe configuration in the hardware setup dialog
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:
The probe factor is directly influencing the measurement result. However, as soon as you
perform a User-Range calibration or a Full-Range calibration, the probe factor has no direct
effect on the measurement result anymore. An external calibration compensates the gain
and phase response of the probes and therefore overrides the probe factor setting.
