Major components of the PCF200 fixture:

• SMA male connector Fast Edge input
• SMA female connector output to AUX IN for 50-ohm termination
• Clip for connection of Solder-In probes
• 2-pin header for connection of Square-Pin probes

The PCF200 provides multiple probe connectors for various kinds of probes. There are 2 circuits depending on the type of probes to calibrate:

• The upper circuit is for Solder-In (SI) and Quick-Connect (QC) probes.
• This circuit can also be used for AT probes using the designated area to apply the probe tips.
• The lower circuit is for Square-Pin (SP) probes.

Probes are connected electrically in a single-ended arrangement: the positive (+) side of the probe must be connected to the signal trace, while the negative (-) side is connected to the ground plane.
