Basic System Measurement Configurations

Basic System Measurement Configurations
A banded millimeter-wave system can be used in either of two basic
configurations, depending on how the test ports are connected to the device
under test (DUT): coaxial measurement configuration or wafer probe
measurement configuration. This document does not describe wafer
configurations.
Millimeter Heads: Input power to the N5293A/95A or OML test ports must
not exceed +20 dBm. Input power in excess of this level will damage
expensive components. Observe proper precautions, especially when
measuring amplifiers with gains of 20 dB or greater.
The maximum input power to the VDI test ports varies between +13 and
+20 dBm. Please consult the VDI's VNAX specifications sheet for details on
your VDI head. Input power in excess of this level will damage expensive
components. Observe proper precautions, especially when measuring
amplifiers with gains of 13 dB or greater.

Coaxial Measurement

In this configuration, the test head modules are placed on a work bench in
front of the millimeter head controller.
The DUT is normally connected to the test ports by way of a 1.0 mm coaxial
cable (test port cable). Connect the DUT to Port 1 (left test head module)
directly, and to Port 2 (right test head module) by way of a test cable. It is also
possible to connect the DUT using a test port cable on each test port, although
this configuration will result in greater signal loss.
Do not attempt to connect a test device directly between the two 1.0 mm
test ports, without at least one test port cable. The test head modules will
not move freely enough to allow such a connection to be made safely.
