2.1.2 Phase Comparison Blocking and
systems using frequency shift
carrier sets
For Phase Comparison Blocking Systems that
have the analog receiver, a skewed hybrid (H1SB-
R or equivalent) must be used on the output of the
LPA to prevent the local receiver from being over-
driven. See Figure 2-2. Having two separate
modules, one for the receiver and one for the
detector/CLI will identify the analog receiver. The
RF interface will need to be set for 4-wire
operation by putting JU1 and JU5 in the OUT
position. The receiver may need to be set to HIGH
SENSITIVITY (JU6) if the system requires more
signal strength.
For systems using frequency shift carrier sets, a
Skewed Hybrid (H1SB-R or equivalent) must be
used between the output of the LPA and the input
of the receiver, to prevent intermodulation. The
RF Interface Module of the TCF-10B must be set
for 4-wire operation by putting JU1 and JU5 in the
OUT position.
2.2 Ordering Information
The LPA50/LPA100 equipment identification
number (catalog number) is located on the left,
front inner side of the chassis. The LPA50/
LPA100 catalog number comprises seven (7)
characters, each in a specific position. This
number tells you whether the chassis is a stand-
alone LPA50 or one of the two chassis for an
LPA100. It also identifies the type of DC power
supply for the chassis.
Table 2-1 provides a complete listing of the
options for ordering an LPA50 or LPA100
assembly, as well as a sample catalog number. To
order one or more LPA50 or LPA100 assemblies,
simply identify the output power and DC voltage
supply you want for each assembly. For example,
the typical catalog number shown in Table 2-1 —
L P A 1 0 0 1
— orders an LPA100 assembly
with a 125 Vdc power supply.
