Installation

Controller / Test Head Interconnections

Sequence of test head connections

NOTE Use a 57 N-cm (5 in-lb) torque wrench to tighten the SMA connectors, and a

90 N-cm (8 in-lb) torque wrench to tighten the 2.4 mm and 3.5 mm

connectors.

The connectors on the backs of the test heads are very closely spaced.

Attaching cables to these connectors is easiest if they are attached in the

following sequence (as illustrated in Figure 2-21 below):

1. b RF OUTPUT; SMA connector

(NOTE: In systems without Option 005, this connector is not used, and

should be ﬁtted with a male SMA termination.)

2. a RF OUTPUT; SMA connector

(NOTE: In systems without Option 005, this connector is not used, and

should be ﬁtted with a male SMA termination.)

3. LO INPUT; 3.5 mm connector

4. MM DRIVE; 2.4 mm connector

5. RF INPUT; 2.4 mm connector

6. BIAS; LEMO multi-pin connector

7. BIAS TEE; SMB connector (if not in use, should be ﬁtted with an SMB

termination)

8. CONTROLLER INTERFACE (multi-pin connector)

Figure 2-21 Test Head Cabling Sequence

NOTE To remove cables from the test head, use the reverse of the sequence

described above.
