10 (53) BRUKER BIOSPIN Operating & Service Manual Version 002
Installation
Environment Requirements 3.1.4
This amplifier is built for inside use only on a maximum elevation of 2000m above
sea level (6600 feet).
No specific cooling or ventilation is required.
Be sure that the amplifier has enough area around it so that the free airs flow into
and out of the amplifier is not obstructed.
It should, however, be in an environment which conforms to the 5°C - 45°C (41°F
- 113°F) thermal specifications, a 80% maximum relative humidity of air and a
contamination level of two (means a normal non-conductive contamination,
temporary conductivity due to condensation is possible).
Installation Requirements 3.2
No special precautions are necessary. Mount the equipment in an area which is
relatively free of vibration, and has sufficient room for cable connections.
The amplifier has a class II installation category.
Bench Operation 3.2.1
The unit can be placed onto a secure flat surface.
Power Requirements 3.3
The BLAH1000 E Amplifier 700-900MHz is designed to be powered by an
additional external switched power supply (P/N:W1304007).
The connection to this power supply is realized via a 500mm cable fitted with a
15 pins DIN 41612-ERNI female connector and coming out from the rear panel of
the amplifier.
It provides all the voltages necessary to the BLAH1000 E Amplifier 700-900MHz
to work. See
"External Power Supply" on page 18 .
System Check 3.4
Before applying power for the first time the following items should be checked:
•
The AC input voltage 208-230 VAC ± 10% range must be compatible with the
power supply.
•
An external blanking (gating) pulse must be supplied to the amplifier in order
for the unit to function. Ensure that this pulse has a proper level and logic
polarity.
•
The BLAH1000 E Amplifier 700-900MHz has a nominal input level of +4dBm.
Ensure that the system drivers are operating at these levels.
•
Output RF loads are connected.
