Prevent Instrument Damage
Caution
To prevent possible damage to the Product or to equipment
under test:
• The front panel Head RF Output and Head Control
connectors on the Product are suited only for use with Fluke
96040A-xx Leveling Heads or the 9600FLT 1-GHz Wide
Offset Filter. Only compatible power sensors should be
connected to the front panel Sensor connectors. No other
connections are permitted.
• The Leveling Heads are fitted with close tolerance metrology
grade N-connectors compliant with MIL-C-39012 and MMC
Standards for Precision N-connectors. When used in
demanding metrology applications the Leveling Heads are
likely to be mated with similar high-quality connectors, thus,
minimizing the opportunity for wear and damage. However,
in applications that require frequent mating or mating to
lower quality connectors, the opportunity for damaging the
connectors increases. On these high-risk occasions,
consider using a sacrificial adapter to prevent damage to
the N connectors.
• Improper mating of 50 Ω and 75 Ω connectors will cause
irreversible damage the center pin. Although appearance is
similar, the dimensions (pin diameter) of 75 Ω differ
significantly from those of 50 Ω. Make sure that the 50 Ω
Leveling Head is mated only to 50 Ω systems and, likewise,
that the 75 Ω Leveling Head is mated only with 75 Ω
systems. Otherwise, mechanical damage of metrology-
grade connectors and out-of-tolerance performance is likely
to occur.
• Very high-grade flexible coaxial transmission line conducts
the RF input signal to 96040A-xx Leveling Heads. As with
any coaxial line, deformation of sidewalls or abrupt bending
can degrade performance. Take care to avoid mechanical
stress or tight bend radius < 60 mm (2.4 in).
• Critical connector mating dimensions could be damaged
during disassembly of a Leveling Head. DO NOT TAMPER with
the four mounting screws at the base of the N-Connector.
Leveling Head disassembly should only be performed by
qualified service personnel at a Fluke Service Center.
