Giga-tronics GT-1000A Microwave Power Amplifier Safety and Manual Conventions
Operation Manual, Part Number 34672, Rev. C, March 2011 Page 1
Chapter 1 Safety and Manual Conventions
This manual contains conventions regarding safety and equipment usage as described below.
1.1 Personal Safety Alert
WARNING: Indicates a hazardous situation which, if not avoided, could result in death
or serious injury.
1.2 Equipment Safety Alert
CAUTION: Indicates a situation which can damage or adversely affect the GT-1000A or
associated equipment.
1.3 Notes
Notes are denoted and used as follows:
NOTE: Highlights or amplifies an essential operating or maintenance procedure, practice, condition or
statement.
Review this manual to become familiar with the instrument safety markings and instructions before operation.
This product is a Safety Class I instrument (provided with a protective earth terminal).
1.4 Before Applying Power
Verify that the product is set to match the available line voltage and the correct fuse is installed.
See Table 13 on page 15.
WARNING
!
CAUTION

Safety and Manual Conventions Giga-tronics GT-1000A Microwave Power Amplifier
Page 2 Operation Manual, Part Number 34672, Rev. C, March 2011
1.5 Electrical Safety Precautions
An uninterruptible safety earth ground must be provided from the main power source to the GT-1000A.
Any interruption of the protective ground conductor (internal or external to the instrument) or
disconnecting the protective earth terminal will cause a potential shock hazard that could result in personal
injury.
Grounding a single conductor of a two conductor outlet is insufficient protection. Additionally, verify that a
common ground exists between the unit under test, any additional test equipment, and this instrument
prior to energizing any unit.
Whenever it is likely that the protection has been impaired, the instrument must be removed from service
and secured against unintended operation.
If this instrument is to be energized via an autotransformer (for voltage reduction), ensure that the common
terminal is connected to neutral.
Servicing instructions are for use by service–trained personnel only. To avoid personal injury, do not perform
any service unless qualified to do so.
Adjustments described in the manual are performed with the unit energized and protective covers removed.
Energy available, at many points, may cause personal injury.
For continued protection against fire hazard, replace the line fuse only with a 250V fuse of the same current
rating and type. Do not use repaired fuses or short circuited fuse holders.
1.6 Important Operating Precautions
The GT-1000A Amplifier does not include an enable/disable feature to activate and deactivate the amplifier.
When connecting or disconnecting the output of the amplifier, ensure that the power switch of the amplifier
is in the OFF position.
The amplifier is capable of power output levels greater than 15 Watts. Devices connected to the output of
the amplifier must be rated to handle 25 Watts or higher. Exceeding the rated output power of a device will
result in permanent damage.
When connecting the amplifier to a transmitting device, observe all safety procedures to ensure that the
amplifier isn’t interfering with other systems in the area. High power microwaves can adversely affect power
sensitive instruments in the area of transmission.
Exercise precautions to avoid exposure to radiated microwave energy at all times.

2.5 Prepare the GT-1000A for Use
2.5.1 Cooling
The GT-1000A has an internal cooling fan. The air intake is located on the rear panel of the instrument. When
using the GT-1000A, ensure there are no obstructions to the flow of air into the instrument.
2.5.2 AC Power Requirements
Fuse Specifications: see Table 13 on page 15.
PROTECTIVE EARTH GROUND
This is a Safety Class 1 product (it includes a protective earth terminal). An
uninterruptible safety earth ground must be provided from the main AC power
source to the GT-1000A’s AC input connector. Observe the following:
If it is possible that the safety earth ground has been impaired, make the
GT-1000A inoperative and secure it against unintended operation.
If the GT-1000A will be powered through an autotransformer, verify that
the autotransformer’s common terminal is connected to the neutral
connector (the grounded side of the Mains supply).
MATCH FUSE TO INPUT AC VOLTAGE
Before applying AC power to the GT-1000A, check that the fuse in the rear of
the instrument (see Replace the Fuse on page 7) has a voltage rating that
matches the AC voltage.
AC Line Cord: All GT-1000A microwave synthesizers are supplied with a 6-foot, three-wire power cord with
three-terminal polarized plug with a safety ground. If a different power cord is used, it must not exceed 3 meters
(9 feet) in order to meet safety requirements.

2.6 Shipping, Repair, and Calibration
2.6.1 Shipping the GT-1000A
If it is necessary to ship the GT-1000A, observe the following:
Use the best packaging materials available. If possible, reuse the original shipping container.
If the original shipping container is not available, use a strong carton (350lbs./sq.in. bursting strength) or a
wooden box.
Wrap the instrument in heavy paper or plastic before placing it into the shipping container.
Completely fill the areas on all sides of the instrument with packaging material. Take extra precaution to
protect the front and rear panels.
Seal the package with strong tape or metal bands. Mark the outside of the package clearly, and in bold type,
as follows:
FRAGILE —DELICATE INSTRUMENT

Chapter 3 Operate the GT-1000A
3.1 Operating Safety and Instructions
This section describes how to operate the GT-1000A Microwave Power Amplifier. Equipment and personal
safety information is also provided.
DO NOT EXCEED AN INPUT LEVEL OF 20 dBm INTO THE GT-1000A. EXCEEDING
THIS LEVEL CAN DAMAGE THE GT-1000A MICROWAVE POWER AMPLIFIER.
WHEN ENERGIZED, THE GT-1000A IS CAPABLE OF SUPPLYING POWER THAT
CAN CAUSE DAMAGE OR INJURY. TAKE THE FOLLOWING PRECAUTIONS TO
ENSURE SAFE SETUP AND OPERATION:
Verify that all cables, connectors, and equipment connected to the
GT-1000A are in good condition.
Do not make connections to equipment while the output of any item of
equipment is energized.
Table 6: Operate the GT-1000A
Operate the GT-1000A
Step
Action
1.
Verify that the output of the signal source driving the amplifier is NOT energized before
continuing to the next step.
2.
Connect the equipment to the GT-1000A according to your application.
NOTE: Verify all mating connectors are 50 Ohm, and that they are in good condition.
3.
Apply AC power to the GT-1000A by turning the front panel power switch ON. Observe that the
POWER ON indicator on the front panel illuminates (see Figure 1 on page 4).
4.
Verify that the output level of the signal source is set below 20 dBm.
5.
Energize the output of the signal source.
6.
If desired, adjust the GAIN knob on the front of the GT-1000A (in normal operation, the gain
adjust is set at maximum).
NOTE: Do not exceed the safe limits of the output power from the GT-1000A into the load. The
load should be rated for at least 30 Watts CW.
