MODEL 3116-192 Block Downconverter

1.0 General

1.1 Equipment Description

The 3116-192 Block Downconverter converts 19.2 - 20.2 GHz to 0.95 - 1.95 GHz with low phase noise and flat

frequency response. Frequency translation is via a 18.25 GHz local oscillator. The gain is +35 ± 2 dB

maximum and is adjustable in 0.5 ± 0.5 dB steps. Front panel LEDs provide indication of Remote operation,

PLL Alarm and DC Power. Gain and internal/external/Auto reference frequency selection are controlled by

front panel switches or remote selection (via RS 232C, standard; Ethernet Optional) and are viewable on the

LCD Display. Connectors are Super SMA female for the RF and BNC female for the L-Band and external

reference input and reference output. In AUTO, the 10 MHz reference stays in external if the external level is

+3 dBm, ±3 dB. The 3116 is powered by a 100-240 ± 10% VAC power supply, and housed in a 1 3/4” X 19 “

X 12” rack mount chassis.

2.0 Installation

2.1 Mechanical - The 3116-192 consists of one RF PCB housed in a 1 RU (1 3/4 inch high) by 12 inch deep

chassis. A switching, ± 12, +24, +5 VDC power supply provides power for the assemblies.

The 3116-192 can be secured to a rack using the 4 holes on the front panel.

Figure 2.0 shows how the 3116-192 is assembled.
