MODEL 3116-22-23# Two Channel Downconverter

1.0 General

1.1 Equipment Description

The 3116-22-23# Two Channel Downconverter converts 2300 ± 100 MHz to 1400 ± 100 MHz (inverted) with a

3.70 GHz (common) local oscillator. The gain is +35 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/485, standard; Ethernet Optional) and are viewable on the LCD Display. Connectors are BNC

female for the RF In and RF Out 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. It is powered by a 100-240 ± 10% VAC

power supply, and is in a 1 3/4” X 19” X 14” rack mount chassis.

2.0 Installation

2.1 Mechanical

The 3116-22-23# is powered by a 100-240 ± 10% VAC power supply, and housed in a 1 3/4” X 19” X 14” rack

mount chassis. The 3116-22-23# can be secured to a rack using the 4 holes on the front panel. Figure 2.0
