3. INSTALLATION AND OPERATION
The Model 9306 Preamplifier contains no internal
power supply and must obtain power from a
separate supply such as that provided in NIM
standard supplies. The 9306 comes equipped with
a captive power cable that mates directly with the
preamplifier power output connectors provided on
many NIM instruments. The power supply should be
turned off while the 9306 is connected or
disconnected.
If only one output of the 9306 is to be used, the
other output should be terminated with a 50-ohm
terminator. A 50-ohm, SMA terminator is available
as an option. Also, it is important to note that it is
not possible to provide input over-voltage protection
at such high frequencies.
Therefore, the magnitude of the input signal must
be less than 1 V. Excessive input voltages will
damage the 9306.
To utilize the high-frequency performance of the
9306, careful signal handling is required. The input
and output cables for the 9306 should be short,
high-quality, 50-ohm cables, since only a few
meters of lossy cable will degrade the signal rise
time. Keep the sum of the input and output cable
lengths less than 1.7 meters to avoid degradation of
the signal rise time. The output cable from the 9306
should be terminated with a 50-ohm impedance that
provides a good match to the cable impedance at 1
GHz.
The 9306 should not be subjected to temperatures
in excess of 50°C.
4. MAINTENANCE
The 9306 requires very little maintenance other than routine removal of dust and tightening of mechanical
connections.
