3-3 INPUT/OUTPUT OPTIONS:
The following paragraphs provide a description of the connections that can be made
to the 8310 Series Attenuator Unit. Figure 1 shows the location of these connectors and switches.
WARNING
Sufficient power levels are present at the Power Input Assembly to cause personal injury.
Ensure that the instrument power cord is DISCONNECTED before attempting to change
fuses.
Figure 1. Front & Rear Panel Connectors
3-3.1 POWER ENTRY MODULE ASSEMBLY:
The Power Entry Module Assembly located on the rear panel contains
a three-prong ac power input connector and a fuse drawer assembly (Figure 1). The
Fuse Drawer Assembly
contains the line voltage fuse (Weinschel P/N 052-1-1.5). The Model 8310 uses a T 1.5A, 250 Vac fuse which is 5 x
20 mm in size. Refer to paragraph 8-4.1 for replacement of the fuse.
The
AC Power Connector
, located on the left side of XF1 (Figure 1), is a plug-type, prong insert connector with three
conductors for connection of the power cord (P/N 068-21) to the Power Supply Assembly located within the Attenuator
Unit. This connector also grounds the chassis of the Attenuator Unit when the ac power cord is connected to a
grounded wall outlet. If necessary, use a three prong to two prong adapter and connect the adapter’s ground lead to
the outlet plate retaining screw.
The
Power ON/OFF Switch
is located on the rear panel and in part of the Power Entry Module Assembly. Placing the
POWER ON/OFF switch in the ON position applies power to the instrument.
CAUTION
When applying an RF signal to the RF INPUT connector, DO NOT exceed the maximum allowable
power level specifications of the Model 8310.
3-3.2. PORTS A-D CONNECTORS:
A typical 8310 Series Attenuator Unit contains 4 four standard D holes
on the front and rear panel allowing for single or multi-channel configurations. Standard Model 8310’s are
supplied with two PLANAR CROWN
®
Type N connectors that can be mounted on the front or rear panel.
These connectors provide a input and output port where various types of RF signals can be applied to the
devices internally mounted in the Model 8310 (Connector location specified by customer when ordering).
Some special configurations could contain Aeroflex / Weinschel’s Model 1568 SMA Panel Adapters or other
types of crowns (see accessories for other types).
