E4991A/B Setup with Coaxial Probe Measurements (Opt. 004)

The E4991A/B Setup is different than that of Network Analyzers. Follow these steps to set up the Dielectric Probe Kit with E4991A/B.

Equipment Used

• E4991A/B option 010 Test Port Extender

• APC 7 to 3.5mm or 2.4mm female adapter or equivalent combination to connect probe to E4991A/B-010

• Probe Stand, N1501A-002

• Mounting Bracket (silver colored with two large thumb screws), N1501A-003 or other lab stand bracket.

• Dielectric Probe

• Adapters may be needed to make connections depending on your configuration. See Adapter Selection Guide

Connections

1. Connect Mounting Bracket to Probe Stand by slipping the opening over the Probe Stand rod, and tightening the two large thumb screws in the back

2. Connect E4991A/B-010 cables to analyzer

3. Connect E4991A/B-010 test port extender to Mounting Bracket using tie wraps or other secure method so that APC7 port connector is facing downward. The probe will be connected to this port later. Make sure there is sufficient space surrounding the probe to be able to calibrate and make measurements.

Calibrate E4991A/B-010

The E4991A/B-010 extended test port requires calibration using the APC7 standards that came with E4991A/B before connecting the probe. Follow the procedure in the E4991A/B firmware.

Connect the probe and adapters as needed to E4991A/B-010 extended test port.
