MODEL 2016-95 Downconverter

1.0 General

1.1 Equipment Description

The 2016-95 Downconverter converts 250 to 950 MHz to 70 ± 18 MHz in 1 MHz steps with low group delay

and flat frequency response. Synthesized local oscillators (LO) provide frequency selection. Multi-function

push button switches select the input frequency, gain, and other parameters. Front panel LEDs provide

indication of DC power, PLL alarm or Remote operation. Gain is adjustable manually (MGC) over a 0 to 50 dB

range. The frequency and gain are remotely selectable. Parameter selection and frequency and gain settings

appear on the LCD display. Connectors are Type F female for the RF, and BNC female for the IF and optional

external 10 MHz reference input and output (option E). Other connector options are available. The 2016-95 is

B) Status Requests -

Table 1.2 lists the status requests for the 2016-95 and briefly describes them.

*PLEASE NOTE: The two character {aa}(00-31) prefix, in the table below,

should be used ONLY when RS-485, (OPTION-Q), is selected.

TABLE 1.2 2016-95 Status Reqquests

Requests

Command Syntax* Description

Command Status {aaS1} Returns {S1bbbbcccIA} where:

• bbbb = Rx frequency

• cc = Rx gain

• I = 1 - spectrum invert enabled

• A = summary alarm; 1=alarmed, 0=normal

10MHz Ref Status {aaS2} Returns {S2E} where:

(option -E only)

• E = 1 - external 10 MHz switched in

2016-95 Manual, Rev. A Page 6 03/07/17

C) Commands - Table 1.1 lists the commands for the 2016-95 and briefly describes them. After a

command is sent the 2016-95 sends a return “>” indicating the command has been received and executed.

General Command Format - The general command format is {aaCND...}, where:

{ = start byte

aa = address (RS-485 only - option -Q)

C = 1 character, either C (command) or S (status)

N = 1 character command or status request

D = 1 character or more of data (depends on command)

} = stop byte

2.0 Installation

2.1 Mechanical - The 2016-95 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-

95 can be secured to a rack using the 4 holes on the front panel. Figure 2.1 shows how the 2016-95 is

assembled.
