1
Connect Test port cables and adapters (if needed) to provide male 2.92 mm
connectors at the measurement planes. Install the BNC 50 ohm terminator to
the E8361A/C VNA’s rear-panel bias input for port 1. This provides a DC 50 ohm
termination for the probe amplifier output.

Procedure
1
Calibrate the PNA to the two male 2.92 mm connectors using the N4692A-00F
ECal module (or equivalent 2.92 mm cal kit).
2
Prepare the N2836A solder-in probe head for connection to the PV fixture as
shown in Figure 100 . Shape the leads as shown with the resistors angled until
they almost touch.

CAUTION
As with all precision connector interfaces, make sure to torque all connections using
the proper torque wrench!
