INTRODUCTION
1.1.
The HP 58516A GPS L1 Distribution
Amplifier is one component of a complete line
of GPS accessories for your GPS antenna sys-
tem available from Hewlett-Packard. These
accessories are designed to deliver precise GPS
signals over a wide temperature range and in
harsh environmental conditions.
1.2.
The distribution amplifier is required if
you wish to distribute the signal from a single
antenna to as many as four GPS receivers.

DESCRIPTION
2.1.
The HP 58516A consists of a broadband,
unity gain amplifier and a 1:4 signal splitter.
Designed for use with GPS antennas, the ~u,lt
features
s
high degree of isolation t o eliminate
feedback and interaction between any GPS
systems connected to it.
ternal power option allows the use of a power
source separate from any of the connected
GPS receivers. A unit with Option 05Q does
not receive power through Port 1.

USE WITH HP AND NON-HP SYSTEMS
3.1.
Although designed for use with HP GPS
frequency and time receivers, the HP 58516A
can be used with other GPS receiver and an-
tenna systems.
3.2. The HP 58516A operates over a voltage
range of +4.5 Vdc to +30 Vdc. Voltage is sup-
plied via the connecting cable (the center con-
ductor is positive with respect to the shield) to
Port 1 of a standard unit, or through an exter-
nal dc power input on a unit with Option 05Q.
Caution: Power to the HP 58516A will
be passed
to
the rest of the antenna sys-
tem. For example, if a +30 Vdc supply is
used to power the HP 58516A, the
+30 Vdc will be passed through to the
antenna. When using the HP 58516A
with an HP 58504A GPS antenna, the
maximum voltage should be no greater
than +5.5Vdc.
