When using with the test head fixed on a handler, etc.
The test head can be attached to a handler or other automatic equipment instead of using a
special test fixture. In this case, secure the test head to the device using the four screw holes
provided in the test head as appropriate. Connect the suitable cable, connectors, test fixture,
etc. for connection of the DUT to the 3.5-mm terminal of the test head.
NOTE
To minimize additional error in measurement, the distance from the test head's 3.5-mm
terminal to the DUT connection side should be kept as short as possible.

Test head
Step 1. Use one or more of the four screw holes in the test head to secure the test head to a handle
or other appropriate location (Figure 2-15 (1)).
For the external dimensions of the test head and the dimensions of the screw holes, see
Figure 12-12, "Test Head Dimensions (in millimeters, typical)," on page 279.
Step 2. Connect the 1-m cable already connected to the test head to the optional 020 Test Head
Extension Cable (1 m) if the original length is insufficient (Figure 2-15 (2)).
Step 3. Connect the three N-type connectors (RF OUT, PORT 1, PORT 2) at the end of the cable to
the respective test head interfaces (RF OUT, PORT 1, PORT 2) on the front panel of the
4287A (Figure 2-15 (3)).
