MODEL 2015-123 Upconverter

1.0 General

1.1 Equipment Description

The 2015-123 Upconverter converts 70 ± 18 MHz to 2025 to 2300 MHz in 1kHz, 10kHz, or 125kHz steps (user

selectable) 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), remote operation (yellow) or the TX carrier is muted (yellow). Variable attenuators for the IF input

and output provide a gain range of -10 to +30 dB 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 IF Input, RF 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 OUT connectors. The RF signal can be

switched between two RF outputs (A and B) via an integrated, remotely controlled RF switch.. The unit is

2.0 Installation

2.1 Mechanical - The 2015-123 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 2015-123 can be secured to a rack using the 4 holes on the front panel. Figure 2.1 shows how

the 2015-123 is assembled.

2.4 Installation / Operation

2.4.1 Installing and Operating the 2015-123 Upconverter

1.) Connect a -10 dBm to -40 dBm, 70MHz signal to IF IN, J4 (Figure 2.2)

2.) Connect the RF OUT A, J101, and RF OUT B, J102, to the external equipment.

3.) Connect 90- 260 VAC, 47 - 63 Hz to AC input 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.) Select the RF Output (A or B) (See Section 2.5 Menu Settings).

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

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 2.4. There is a spare fuse in the near slot. If a fuse

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