Description
This section provides a detailed functional description of the
features, operation, and options for Model 5601. The wideband
amplifier may be ordered with different configurations such as
input/output impedance and gain. Read the following
description carefully and make sure your amplifier is configured
correctly for your application before you install and use this
card.
Options
Model 5601 must be ordered from the factory already
configured for your application. It is not user-configurable
except the grounding option (grounded/floating). Optional
configurations for Model 5601 include:
Input Impedance
– determines the matching impedance at the
input connector. Two options are available: 50
W
and 1M
W
.
Output Impedance
– determines the output impedance
matching for the load impedance. Three options are available:
50
W
, 75
W
, and 600
W
.
Gain
– specifies gain magnitude of the input signal. Factory
default setting is 10. However, any custom gain up to 100 can
be specified. Note that some characteristics of the output
section may change for gain settings above 10.
Output Polarity
– specifies the phasing of the amplifier. Two
options are available: Normal and Inverted.
Circuit Ground
– determines if the amplifier ground is floated
or tied to case ground. This is the only user-configurable option,
and may be changed by adding or removing a jumper
connection.
All options must be specified at the time of purchase. Model
5601 is supplied fully configured. Only qualified personnel may
do reconfiguration (other than grounding) of fielded cards.
