MODEL 2016-05A Downconverter

1.0 General

1.1 Equipment Description

2016-05A L-Band Downconverter converts 950 to 1525 MHz to 140 MHz in 1 MHz steps with low group

delay and flat frequency response. The 2016-05A Input and Output levels have been optimized to support

transmit from an L-band modem to a 140 MHz IF upconverter. 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). The gain is adjustable from 0 to +50 dB. Remote operation allows

selection of frequency and gain. Parameter selection and frequency and gain settings appear on the LCD

display. Standard connectors are BNC female for IF output and the optional external reference input and

reference output, and Type F female for the RF input. A high stability (±0.01ppm) reference, LNB +24 VDC,

0.4 Amps power and 10 MHz reference (includes a 10 MHz output connector), are available Options. The unit

is powered by a 100-240 ±10% VAC power supply, and housed in a 1.75” X 19” X 16” 1RU chassis.

2.0 Installation

2.1 Mechanical

The 2016-05A consists of one RF/Controller PCB 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 assemblies. The 2016-05A can be

secured to a rack using the 4 holes on the front panel. Figure 2.1 shows how the 2016-05A is assembled.

2.4 Operation

2.4.1 Installing and Operating the 2016-05A Downconverter

1. Connect a -20 dBm to -70 dBm signal to RF IN, J2 (Figure 2.2)

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

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

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

5. Set the gain for +00.0 to +50.0 dB (See Section 2.5 Menu Settings).

6. Be sure DS6 (green, DC Power) is on and DS3 (red, Alarm) is off (Figure 2.3).

7. Option L only - To insert LNB +24 VDC on the RF center pin install 0.5A fast blo fuse in F1 and check

that DS8 lights yellow (Figure 2.1)

8. 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.
