2.0 Installation
2.1 Mechanical
The 2005 is packaged in an aluminum extrusion. The -R option is mounted on a 1 3/4” X 19”panel that can be
mounted to a rack using the 4 holes at the ends. Both units derive +DC from the RF out center conductor (+14 to
+20 VDC) or the wall power supply (+15VDC unregulated). See Figure 2.3.
2.1.1 Cleaning Instructions
Wipe the exterior with a dry, soft cloth. Use no detergent or cleaning chemicals.
2.2 Front Panel Controls and Indicators
Figure 2.1 shows the controls and indicators located on the front panel.
SW6 - LO SIDE SELECT
SPDT slide switch selects high side (C)
or low side (Ku) local oscillator.
DS1 - DC POWER LED
Lights green when DC power
is present
SW1 to SW4 - FREQ SELECT SWITCHES
BCD switches select the desired output frequency
which is the Local Oscillator frequency - 70 , -140,
+70, or +140 MHz.
DS2 - ALARM LED
Lights red when PLL
comes out of lock
SW5 - IF SELECT
SPDT slide switch selects
70 or 140 MHz IF in.

2.3 Rear Panel Inputs, Output, and Controls
Figure 2.2 shows the inputs, outputs, and controls located on the rear panel of the 2005.
J1 - IF INPUT
The IF 70 or 140 MHz
input . This is a 75
Ω
,
BNC input at -10 dBm
max level for LOW GAIN
(-30 dB) and -30 dBm
max level for HI GAIN (-
10 dB). The gain is
selected by SW7.
J3 - DC POWER
The +15 VDC unregulated DC voltage
from the wall power supply.
J2 - RF OUTPUT
The mixed RF output.
This is an unfiltered
output and contains
mainly the LO- IF, LO,
LO + IF, mixer products.
This is a 75
Ω
, Type F,
female connector.
