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.

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.

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.

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.

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.

The Wide FM mode is ordinary used to interpret a large signal of
bandwidth; the Narrow FM mode is used to interpret a narrow Bandwidth
Signal. AM and SSB can be used irrespective of Bandwidth.
Push Mode (MHz)
Key to establish the reception mode and then
the top-left ICON will be changed to WFM , NFM , AM
, SSB in order. When inputting frequency like Start/Stop,
Span etc, The Mode (MHz)
Key is used.
RBW is fixed in each Mode as follows.
Wide FM RBW (Resolution Bandwidth) 180 kHz
Narrow RBW (Resolution Bandwidth) 12.5 kHz
SSB/AM RBW (Resolution Bandwidth) 2.4 kHz
STEP 1
- Push the Mode (MHz) Key.

Sweep Mode
The Sweep mode is used to interpret the characteristics of input signals.
Every each characteristics of the sweep mode is as follow.
Establish this mode by pushing the Sweep (kHz)
Key and then the
top left ICON will be changed to FREE Run , SQUELCH Run
and SINGLE Run in order. The Sweep (kHz) Key is used as
input Start/Stop, Span and Input Frequency Unit into kHz Unit.
After frequency is inputted, FREE Run continues to execute Run-
Scanning operation automatically.
Squelch Run operation will stop Run-Scanning in case of the signal
level value is getting higher than the squelch level value. But, If the signal
level is getting lower than the squelch level, restart to Run- Scanning.
After input is finished Start/Stop Frequency,
Single Run execute
Run-Scanning just a once. In addition, if it is desired to Run-Scanning,
push the Run (GHz)
Key and then execute Run-Scanning once
STEP 1
- Push the Sweep (kHz) Key
STEP 2
- Push the Sweep (kHz) Key, and the top-left ICON will be

Set up Span
Setting of step for Span means Frequency Resolution and Span can be
adjusted from 1MHz to 400MHz. And the step at Narrow FM, SSB and AM
can be set 1MHz to 2MHz. Wide FM from 1MHz to 20MHz is 1MHz step
and step at 20MHz to 400MHz can be set at 20MHz step.
If the correct value is not set, value will be set at a lager value
automatically.
Example) If Span Input is 50 MHz, it would automatically be set at 60
MHz.
First, push the Shift Key in order to set up Span. Then the top-left
ICON is changed
to .
After that, push the No. 2 Key. So then Frequency Input window changes
the Span Input State.
Enter the span size and then input the appropriate unit such as Run
(GHz)
, Mode (MHz) or Sweep (kHz) Key.
STEP 1
- Push the Shift Key
STEP 2
- Push the No. 2 Key
- When the Sweep (kHz) Key is pressed, the top-left ICON is
changed to FREE Run, SQUELCH Run and
SINGLE Run in order.

Frequency Input
Chosen Reception Mode, Sweep Mode and Span are showed on the top
center of LCD. At first, choose Reception Mode and Sweep Mode to get a
sense of the Frequency Bandwidth and a specific feel for analyzing.
Choosing Frequency Value is a way to inputting Center and Start/Stop
Frequency. In order to input Center Frequency, just pushes the numeral
keys. Press the key when Frequency Input Window is a CENT state.
Push the Shift Key to input Start/Stop Frequency. Then, push the
No. 1(Start/Stop)
Key, to input Start Frequency in Frequency Input
Window. Input Frequency by using the No. 0
to 9 Keys, Dot
(Buzzer)
Key, MARKER (DEL) Key and Run (GHz)
as Unit Input Key, Mode (MHz)
and SWEEP (kHz) Key.
Execution will be done automatically, after inputting the last Unit in the
Frequency, according to a given Sweep Mode of Run-Scanning Mode. If
the mode is Single Run
, push the Run (GHz) Key and then
execute Run-Scanning again.
A wrong inputting content can be erased by using the MARKER (DEL)
Key. The MARKER (DEL) Key operates like the backspace
on a PC
Erase inputted Frequency and then push the Marker (DEL) Key once
more; you are now out of Frequency Input Mode.
