Connecting the Test Head
When performing calibration with the 7-mm Calibration Kit or measuring DUTs
with the test fixture and 7-mm terminal, you must first connect the test head to
the E4991B. The procedure for making this connection is described below.
When connecting the test head:
• Do not remove the four feet on the bottom of the E4991B; doing this would
make the connection more difficult.
• Turn the N-type connectors in the order given in the instructions below
when tightening them. The N-type connector for the RF OUT terminal is
mounted with a special design for flexible movement to provide easier
connection or removal of the test head.
Figure 1-3 Connecting Test head to E4991B
1. Attach the N-type connectors (test head side) to their corresponding
terminals (RF OUT, PORT 1 and PORT 2), which serve as the test head
interface of the E4991B.
2. Turn the N-type connectors for PORT 1 and PORT 2 at the same time to
tighten them.
