Safety Instruction
No Unauthorized Disassembling
Do not remove the instrument cover. Only GS Instruments’ Service technicians are
allowed to repair the instrument. Instruments that appear damaged or defective
should be secured against unintended operations until they are repaired
by qualified service technicians. Also, unauthorized disassembling makes
the warranty void.
Keep the power connectors clean
Instrument’s power connectors should remain dust free.
Clean the power connectors regularly. Dust could result in damage to this instrument.
Also, continually cleaning the dust on the input terminal of RF frequency counter.
Clean the input terminal regularly. Dust could result in damage to the instrument.
RF in/output rating
Rating of RF input and output connector
Maximum DC voltage rating
RF input connector (socket): N type female, 50Ohms
Maximum RF input power: 5Vrms
Caution: Do not use over 5Vrms supplied and/or (-) power could result in damage to this
instrument
Do not operate this instrument if there is any doubt it is functioning properly: if
operating personnel feel the instrument is not operating properly, return this instrument
to GS Instrument for service and repair to ensure the safety features are maintained.
5
DC Power
The operating personnel must use the DC adaptor included in the package. Other
unauthorized adaptors could result in damage to this instrument and it is out of warranty. The
DC connector tip must attach with (+) polar grounding.
The operating personnel must use grounded power to operate this instrument
Safekeeping Place
Do not attempt to operate this instrument for long durations and avoid restoring this instrument
in the following conditions.
＊Avoid direct sun lights
＊Keep away heating systems
＊Avoid high temperature (Ex. Inside of the car during the summer time)
＊Keep away from liquids
＊Avoid high moisture and/or poor ventilation
＊Keep away from dust and/or smoke
＊Avoid extremely low temperature
Battery
Protek 7830 Ni-MH battery is rechargeable. Battery is recharged based on the battery
temperature. Charging is controlled from the power of the battery cell and the temperature of
the battery. The Ni-MH Rechargeable battery is going to increase temperature slowly until the
temperature is extremely higher. Battery charging is finished automatically by checking the
degree of the temperature (dT/dt). For battery protection, when the power of Battery cell is
increased, comparing regular temperature and/or exterior temperature degree of when the
temperature increases over 50 degrees, battery charging will be finished automatically.
6
Operating personnel must use Ni-MH Rechargeable Battery and do not operate near
explosives
- The battery usage time can change due to the using period, environment and
temperature.
- As time goes by, the battery-running time will decrease and eventually need to replace.
Operating personnel should phase in a new battery when the battery-running time is less than
half hour (The warranty period is 6 month, after instrument use has begun.)
- Operating personnel should not use this instrument and/or keep the battery in place for
long periods of time, which could result in discharging of the battery.
- To avoid damages to battery, when battery is low, this instrument will turn off
automatically.
7
Warranty

Overview
The Protek 7830 is a handheld spectrum analyzer and it is optimized to
analyze signals for the radio frequency equipment. The Protek 7830 has
adopted a synthesizer method and has a wideband reception range of
100 kHz to 2,900 MHz. The characteristics of frequency response of the
Protek 7830 is that the measuring data are corrected by memorized
calculation data, and so it enables Protek 7830 to measure accurate
levels and make it possible to analyze easily for a wide range of
frequency bands.
The Protek 7830 provides various functions and user-friendly interfaces
which make it easy for the users to check the location of the antenna with
simple handling. The Spectrum Analyzer is ideal for users to test, install
and maintain mobile telecommunications systems, cellular and cordless
phones, CB paging, paging systems, Cable and Satellite TV Systems as
well as antenna site measurements and maintenance. The Protek 7830
supports the RS 232C serial communication and has separate GUI
software. Users can control the Protek 7830 easily after connecting the
Protek 7830 with their personal computer, and can utilize the analyzed
data variously after converting or saving numerical values or graphs.
