MODEL 2016-75-213 Downconverter

1.0 General

1.1 Equipment Description

The 2016-75-213 Downconverter converts 719 MHz to 201.143 or 213.143 ± 3 MHz with low group delay and flat frequency response. Synthesized local oscillators (LO) provide output frequency selection. Multi-function push button switches select the output frequency, gain, and other parameters. Front panel LEDs provide indication of DC power (green), remote operation (yellow), and PLL alarm (red). Variable attenuators for the

RF input provide a gain range of 0 to +40 dB as adjusted by the front panel multi-function pushbutton switches.

Remote operation allows selection of output frequency and gain. Parameter selection and frequency translation and gain settings appear on the LCD display. Connectors are Type F female for the RF and BNC female for IF and optional 10 MHz input and output signals (option -E). A high stability (±0.01ppm) (option -H) is also available. The unit is powered by a 100-240 ± 10% VAC power supply, and housed in a 1 3/4” X 19“ X 16” rack mount chassis.

2.4.1 Installing and Operating the 2016-75-213, Upconverter Section

1. Connect a -10 dBm to -40 dBm signal to IF In, J4 (Figure 2.1)

2. Connect the RF OUT, J5, to the external equipment

3. Connect 100-240 ± 10% VAC, 47 - 63 Hz to AC1 on the back panel.

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

5. Set the input level (See Section 2.5 Menu Settings).

6. Set the gain for -10 to +30 dB. Make sure the output stays within -20 to 0 dBm with the gain selected and the input level provided. The firmware will prevent setting gain and input level outside this range.

(See Section 2.5 Menu Settings).

7. Be sure DS6 (green, DC Power) is on and DS2 (red, Alarm) is off (Figure 2.2).

8. Option -V only - To insert SSPB +24 VDC on the RF center pin install 2.5A fast blo fuse in F2 and check that DS7 lights yellow (Figure 2.1)

9. 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 2.3. There is a spare fuse in the near slot. If a fuse continues to open, the power supply is most likely defective.
