MODEL 1586-04-0431 RF Attenuator
1.0 General
1.1 Equipment Description - The 1586-04-0431 Programmable Attenuator contains two 0.5 to 4 GHz and two
25 to 31 GHz Digital PIN Attenuators and Local/Remote control circuitry to independently adjust each
attenuator. Multi-function push button switches select the attenuation locally. The attenuator values are stored
in nonvolatile memory so these values remain when power is cycled off and on. Front panel LEDs provide
indication of DC power (green), Alarm (red), and Remote (yellow). Each Attenuator provides an attenuation
range of 60 dB from 10 to 70 dB attenuation. Remote operation also controls each attenuator, provides status
monitoring of attenuator settings, power supply, and summary alarms. Attenuator settings appear on the LCD
display. An “Offset” command allows adding an external attenuator to shift the attenuation range by the
amount of the attenuator with the total attenuation shown on the display and via the M&C. Connectors
are SMA, female (CH1, CH2) or 2.92 mm (CH3, CH4) for inputs and outputs and DB9 female for the RS422
remote control (Ethernet Optional). It is powered by a 100-240 ±10% VAC power supply (Option -R for
redundant supplies), and in a 1 3/4” X 19 “ X 16” rack mount chassis.

2.0 Installation
2.1 Mechanical - The 1586-04-0431 consists of one Controller PCB assembly, two General Microwave Model
346C 10 Bit Digital PIN Attenuators and two General Microwave Model 3499 11 Bit Digital PIN attenuators
housed in a 1 RU (1 3/4 inch high by 19 inch deep) chassis. One 100-240 VAC, 25W power supply provides
redundant power for the assemblies. The 1586-04-0431 can be secured to a rack using the 4 holes on the front
panel. Figure 2.0 shows how the 1586-04-0431 is assembled.

2.4 Installation / Operation
2.4.1 Installing and Operating the 1586-04-0431 RF Attenuator
1.) Connect 0 to -20 dBm signal(s) to any or all of the four RF Attenuator Inputs (Figure 2.1).
2.) Connect the desired RF Attenuator Outputs to the external equipment (Figure 2.1).
3.) Connect 100-240 ±10% VAC, 47 - 63 Hz to AC1 and/or AC2 on the back panel.
4.) Set the desired gain and attenuation offset for each attenuator (See Section 2.5 Menu Settings).
5.) Be sure DS1 (DC Power) is green (Figure 2.2).
6.) AC Fuses - The fuses are 5 mm X 20 mm, 2 amp slow blow (Type T) and are inserted in the far slot
in the drawer below the AC inputs 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.

2.5 Menu Settings
2.5.1 Functions
This section describes operation of the front panel controls. There are three ope rator switches, the LCD display
and alarm indicator LEDs. All functions for the equipment are controlled by these components. The functions
are (see Figure 2.5):
Power Up
Normal Display
Menu 1 CH 1 GAIN, OFFSET
Menu 2 CH 2 GAIN, OFFSET
Menu 3 CH 3 GAIN, OFFSET
Menu 4 CH 4 GAIN, OFFSET
Menu 5 Set REMOTE
Menu 6 Set Interface
Menu 7 Set RS485 address
Menu 8 Reset Ethernet Settings
Save Menu When “R” is selected in any above menu or the next menu item after Menu 8
Alarm indications appear on the LEDs (see figure 2.2).
All program changes must start with the operation of the Menu/Execute switch and must also end with the
operation of the Menu/Execute switch verified by the “Save Settings?” Menu. If this sequence is not followed,
none of the changes will take effect. If programming is initiated and no operator action takes place for
approximately 12 seconds (before the final press of the Menu/Execute switch) the display will revert to its
previous status and you will need to start over.
1586-04-0431 Manual Page 13 4/12/21

2.5.2. Power On Settings
NOTE: The last status of a unit is retained even when power is removed. When power is restored, the unit
will return to it's previous settings.
When power is first applied, the LCD display goes through three steps.
1. The LCD goes black to show all segments are functioning.
2. The software version will be displayed.
REV 5.20
3. The present gain of each attenuator is shown.
G1=-33.0 G2=-41.0
G3=-17.0 G4=-52.0
The unit is now operational and ready for any changes the operator may desire.
2.5.3 Control Switches
1. Menu/Execute - Any change to the programming of the unit must be initiated by pressing the
Menu/Execute switch and completed by pressing the Menu/Execute switch.
2. Horizontal Switch - This switch is mounted so its movement is horizontal and moves the cursor left or
right.
3. Vertical Switch - This switch is mounted so its movement is vertical and has two functions:
A. During frequency, gain changes, the vertical movement will raise or lower the selected number
in the direction of the arrows.
B. For other functions, the vertical switch will alternately turn the function on or off regardless of
the direction operated.
1586-04-0431 Manual Page 14 4/12/21

2.5.4 Gain and Offset Changes
The nominal gain through each channel is adjustable from -10.0 dB to -70.0 dB. Each channel has an offset
value that allows you to add external attenuation that will automatically be reflected in the gain value displayed
for that channel. The offset value is adjustable from 0 to 60 in 1 dB steps.
The gain and offset changes will be made as you make them but if you do not wish to save the
changes you have made, scroll to “R” and push the menu/Execute switch and select “NO” in the “SAVE
SETTINGS?” window or do not press the Menu/Execute switch; simply do nothing for approximately 30
seconds, and the system will return to the normal operating mode.
To change the GAIN or OFFSET, first push the Menu/Execute switch to get to the desired channel’s gain/offset
menu setting:
Operate the Menu/Execute switch until you get to the menu item you want to change (see Figure 2.5 for
the sequence of menu options). The following display is for changing the gain and offset for channel 1:
CH1 GAIN=-33.0
CH1 OFFSET=+20 R
NOTE: CHANGES TAKE PLACE ON GAIN AND OFFSET IMMEDIATELY BUT DO NOT GET
SAVED UNTIL YOU GO TO THE SAVE MENU AND INDICATE YOU WANT TO SAVE THE
CHANGES.
Press the Up/Down switch to change the gain in 0.5 dB steps. Use the left/right switch to navigate from
gain to offset. Press the Up/Down switch to adjust the external attenuation offset value. The gain value
will be adjusted to reflect the new offset value at the time that the changes are made.
NOTE: THE GAIN AND OFFSET WILL BE CHANGED AS YOU ADJUST THE NUMBERS.
HOWEVER, THE VALUE WILL NOT BE STORED UNTIL YOU INDICATE YES IN THE SAVE
SETTINGS WINDOW.
When the display indicates the value desired you can push the Menu/Execute switch to the next item
OR you can scroll to “R”, push the Menu/Execute switch to get to:
SAVE SETTINGS? YN
Selecting Ywill save the new settings. Selecting Nwill revert to the previous settings.
Pushing the Menu/Execute switch then takes you to:
G1=-33.0 G2=-41.0
G3=-17.0 G4=-52.0
Figure 2.5 gives the menu items and how to make changes
1586-04-0431 Manual Page 15 4/12/21

2.5.5 Alarm Indications
An alarm condition for will occur if the l+12 VDC or -12VDC power supplies (to the internal attenuators) are
out of range.

1.4 Environmental Use Information
A.Rack-Mounting - To mount this equipment in a rack, please refer to the installation instructions
located in the user manual furnished by the manufacturer of your equipment rack.
B. Mechanical Loading - Mounting of equipment in a rack should be such that a hazardous condition
does not exist due to uneven weight distribution.
C.Elevated Operating Ambient Temperature - If installed in a closed or multi-unit rack assembly,
the operating ambient temperature of the rack may be greater than room ambient temperature.
Therefore, consideration should be given to Tmra.
D. Reduced Air Flow - Installation of the equipment in a rack should be such that the amount of air flow
required for safe operation of the equipment is not compromised. Additional space between units
may be required.
E. Circuit Overloading - Consideration should be given to the connection of the equipment to the supply
circuit and the effect that overloading of circuits could have on over current protection and supply wiring.
Appropriate consideration of equipment name plate rating should be used, when addressing this concern.
F. Reliable Earthing - Reliable earthing of rack-mounted equipment should be maintained. Particular
attention should be given to supply connections other than direct connection to the Branch
(use of power strips).
G. Top Cover - There are no serviceable parts inside the product so, the Top Cover should not be removed.
If the Top Cover is removed the ground strap and associated screw MUST BE REINSTALLED
prior to Top Cover screw replacement. FAILURE TO DO this may cause INGRESS and/or EGRESS
emission problems.
