MODEL 2016-12 Downconverter

1.0 General

1.1 Equipment Description

The 2016-12 Downconverter converts 950 to 2150 MHz (in 1 kHz, 10 kHz, or 125 kHz steps - user selectable)

to 70 ± 18 MHz with low group delay and flat frequency response. Synthesized local oscillators (LO) provide

very low phase noise and ±0.01 ppm stability frequency selection. Multi-function push button switches select

the RF frequency, gain, and other parameters. Front panel LEDs provide indication of DC power (green), PLL

alarm (red), and remote operation (yellow). Gain is adjustable manually over a 0 to +50 dB range as adjusted

by the front panel multi-function push-button switches. Remote operation allows selection of frequency and

gain. Parameter selection and frequency and gain settings appear on the LCD display. Connectors are BNC

female for RF Input, IF outputs and the 10MHz external reference input and 10MHz reference output.

The 10MHz reference signal (internal or external) can be sent to the 10MHz reference output connector and/or

to the RF IN connector. The unit is powered by a 100-240 ±10% VAC power supply, and housed in a 1.75” X

19 “ X 16” rack mount chassis.

2.0 Installation

2.1 Mechanical - The 2016-12 consists of one RF/Controller PCB which is housed in a 1 RU (1 3/4 inch high)

by 16 inch deep chassis. A switching, ± 12, +24, +5 VDC power supply provides power for the assembly. The

2016-12 can be secured to a rack using the 4 holes on the front panel. Figure 2.1 shows how the 2016-12 is

assembled.

2.4 Installation / Operation

2.4.1 Installing and Operating the 2016-12 Downconverter

1.) Connect a -70 dBm to -20 dBm, 950-2150 MHz signal to RF IN, J4 (Figure 2.2)

2.) Connect the IF OUT, J1, to the external equipment.

3.) Connect 100-240 ±10% VAC, 47 - 63 Hz to AC input on the back panel.

4.) Set the desired input frequency (See Section 2.5 Menu Settings).

5.) Set the gain for 0 to +50 dB (See Section 2.5 Menu Settings).

6.) Be sure DS6 (green, DC Power) is on and DS2 (red, Alarm) is off (Figure 2.3).

7.) AC Fuse - The fuse is a 5 mm X 20 mm, 2 amp slow blow (Type T) and is inserted in the far slot in

the drawer below the AC input as shown in Figure 2.4. There is a spare fuse in the near slot. If a fuse

continues to open, the power supply is most likely defective.
