Required Equipment
2-2
This section lists the test equipment needed to run performance tests and adjustments, any critical
specification requirements, and recommended model numbers. The computer and all test equipment are
connected to the device under test (DUT) using GPIB.
CAUTION
In all test equipment configurations, cables and adapters need to be properly torqued.
Exceeding recommended torque values may cause damage to a cable or adapter and may cause
inaccurate test results.
NOTE
• All test equipment requires a 30 minute warm-up period to ensure accurate performance.
• Models for each Test Equipment category are given in order of preference. Alternate or
substitute models are listed after the preferred model, but should be considered as a lower
priority.
• It is recommended that all amplifiers be placed in enclosures. This should help reduce the
effect of signals radiating into adjacent equipment. It is also recommended that amplifiers
are not physically positioned close to equipment that can radiate low-level RF signals.
Connector Type
Torque Value
APC 3.5
Use an Agilent 8710-1765 at 8-lb inch when
connecting APC 3.5 (m) to APC 3.5 (f).
SMA
Use an Agilent 8710-1765 at 8-lb inch when
connecting APC 3.5 (m) to SMA (f).
Use an Agilent 8710-1582 at 5-lb inch when
connecting SMA (m) to APC 3.5 (f).
Type-N
Type-N connectors may be connected finger tight. If a
torque wrench is used, Agilent 8710-1766 at 12-lb inch
is recommended.
