Basic System Measurement Configurations
The N5290/1A 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.
Coaxial Measurement
This configuration is used when the DUT has coaxial connectors. The
N5290/1A test ports have 1.0 mm male coaxial connectors, and are designed
to cover a frequency range of 900 Hz to 110 GHz (N5290A) or 900 Hz to
120 GHz (N5291A).
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 a DUT (with female connectors) to Port 1 (left
test head module) directly, and to Port 2 (right test head module) by way of a
female to female 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. (i.e., Devices with female connectors can connect directly to the
test ports. Devices with male connectors require a female to female cable.)
shows how the instruments are configured on a work
bench for the coaxial measurement configuration. The test head modules are
placed on the bench top in front of the PNA and controller.
Input power to the test ports must not 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.
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.
