DISCLAIMER
Buyer acknowledges and agrees that it is responsible for the operation of the goods purchased and should
ensure that they are used properly and in accordance with this document and any other instructions provided
by Seller. Astronics Test Systems products are not specifically designed, manufactured or intended to be used
as parts, assemblies or components in planning, construction, maintenance or operation of a nuclear facility, or
in life support or safety critical applications in which the failure of the Astronics Test Systems product could
create a situation where personal injury or death could occur. Should Buyer purchase Astronics Test Systems
product for such unintended application, Buyer shall indemnify and hold Astronics Test Systems, its officers,
employees, subsidiaries, affiliates and distributors harmless against all claims arising out of a claim for personal
injury or death associated with such unintended use.

FOR YOUR SAFETY
Before undertaking any troubleshooting, maintenance or exploratory procedure, read carefully the WARNINGS
and CAUTION notices.
This equipment contains voltage hazardous to
human life and safety, and is capable of inflicting
personal injury.
If this instrument is to be powered from the AC line (mains) through an autotransformer,
ensure the common connector is connected to the neutral (earth pole) of the power supply.
Before operating the unit, ensure the conductor (green wire) is connected to the ground
(earth) conductor of the power outlet. Do not use a two-conductor extension cord or a
three-prong/two-prong adapter. This will defeat the protective feature of the third
conductor in the power cord.
Maintenance and calibration procedures sometimes call for operation of the unit with power
applied and protective covers removed. Read the procedures and heed warnings to avoid
“live” circuit points.
Before operating this instrument:
1. Ensure the proper fuse is in place for the power source to operate.
2. Ensure all other devices connected to or in proximity to this instrument are properly grounded or connected
to the protective third-wire earth ground.
If the instrument:
- fails to operate satisfactorily
- shows visible damage
- has been stored under unfavorable conditions
- has sustained stress
Do not operate until performance is checked by qualified personnel.

Introduction –
1260-164AH/BH
The 1260-164AH and 1260-164BH are microwave plug-in switch
modules developed for a variety of platforms such as the 1260-100
Adapt-a-Switch™ carrier and the 1256 Switching System. These
switches are software-configurable single (–164AH) and dual
(–164BH) SP4T microwave relays for DC to 26.5 GHz.
The 1260-164 modules include the following features:
•Standard Adapt-a-Switch and 1256 Switching System plug-in
design, providing for ease of replacement.
•Data-
Driven embedded descriptor, allowing immediate use
with any platform compatible with the Adapt-a-Switch
standard, regardless of firmware level.

Power
Dissipation –
1260-164AH/BH
The cooling of the Adapt-a-Switch carrier is dependent upon the
chassis into which it is installed. The carrier can nominally
dissipate approximately 100 W. Even with all channels driven to
maximum outputs, up to two 1260-164AH plug-ins may be used
together in a 1260-100 without exceeding the maximum allowable
power dissipation of the carrier.
If the 1260-164AH will be used in conjunction with other cards, the
dissipation should be computed and summed with the total worst-
case dissipation of the remaining modules.
For example, a 1260-164AH module would dissipate the following
energy:
Quiescent power dissipation = 0.75 W maximum
With one coil energized = 3.75 W maximum
For example, a 1260-164BH module would dissipate the
following energy:
Quiescent power dissipation = 0.75 W maximum
With one coil energized = 3.75 W maximum
With two coils energized = 7.50 W maximum
This is acceptable power dissipation for an individual plug-in
module. If one additional module is likewise loaded, then the
overall carrier dissipation is approximately 7.5 W for the –164AH
and 15 W for the –164BH, both of which are well within the cooling
available in most commercial VXIbus chassis.

INSTALLATION INSTRUCTIONS
Unpacking and
Inspection
1. Remove the 1260-164 module and inspect it for damage. If any
damage is apparent, inform the carrier immediately. Retain
shipping carton and packing material for the carrier’s inspection.
2. Verify that the pieces in the package you received contain the
correct 1260-164 module option and the 1260-164AH/BH User
Manual. Notify Customer Support
if the module appears
damaged in any way. Do not attempt to install a damaged
module into a VXI chassis.
3. The 1260-164 module is shipped in an anti-static bag to prevent
electrostatic damage to the module. Do not remove the module
from the anti-static bag unless it is in a static-controlled area.

Installation Instructions 2-6 Astronics Test Systems
Mating Connectors Mating connectors are SMA type. Use connectors that are suitable
for the type of connecting coax and frequency range to be used.
Maximum connector engagement should not exceed 9 in. lbs.
torque. It is highly recommended that a torque wrench (Ma-Com
P/N 2098-5065-54 or equivalent) be used to
torque the SMA
connectors. A ¼-inch drive deep slotted s
ocket, P/N 456890, is
available for installation and removal of connectors.
