INTRODUCTION:
The SS-10 Field Strength Meter is ideal for reading relative
field strength from your antenna.
It is a compact unit that fits in the palm of your hand and can be
taken anywhere.
The best part of using it is that you now can tell if your
antenna is radiating or not by simply holding the unit near
your antenna and adjusting the sensitivity. Also, by taking
measurements, you can find out relatively how strong your
antenna field is. Operation The SS-10 Field Strength Meter is
very simple to use. It requires no power because your
antenna field provides the power necessary to run the meter.
Simply raise the single whip antenna on your unit, stand several
feet away, and adjust the sensitivity knob on the front, it’s that
easy.
You want to ensure that the whip antenna is parallel with the
polarity of the antenna you are reading.
Now you can read the relative field strength of your antenna.
Technical Assistance If you have any problem with this unit first
check the appropriate section of this manual. If the manual does
not reference your problem or your problem is not solved by
reading the manual you may call SURECOM Technical Service
at [phone]. You will be best helped if you have your unit,
manual and all information on your station handy so you can
answer any questions the technicians may ask. You can also
send questions by E-mail to SURECOM.COM.HK
Features:
The appearance is simple and efficient, beautiful and generous.
Frequency bandwidth, high sensitivity. 100KHz-3000MHz (with antenna
), please use different frequency antennas to test signals with different
frequencies for better effect and sensitivity)
The pointer amplitude can be adjusted (to protect the meter)
Built-in automatic damping function, which is the buffer function,
prevents the needle from swinging too fast and causing damage.
Small size, easy to carry, size: 75 x 100 x 64mm (excluding the raised
antenna part)
Instructions for use:
Before use, please rotate the "amplitude adjustment" to the left most
end. The length of the antenna to be pulled depends on the
frequency of the test. It is better to have 1/4 wave as much as
possible. The handheld walkie-talkie is about one meter away from
the field strength meter. Don't be too close! In order to avoid the
signal is too strong to burn the field strength meter! Then press the
walkie-talkie PTT button to make the walkie-talkie enter the launch
state. At this time, the pointer of the field strength meter should
have a signal indication. The stronger the signal, the greater the
indication!
Amplitude adjustment: If the field strength indicator indicates that
the maximum range is exceeded, the "amplitude adjustment" can be
adjusted to let the pointer indicate the appropriate position.
Method for testing the maximum gain point of an antenna
1. In order to change the frequency conveniently and quickly, you
should use the keyboard to set the frequency walkie-talkie manually.
2. Link the walkie-talkie and antenna feeders, place the field
strength meter near the antenna (depending on the environment),
place it within the vertical radiation angle of the antenna as much as
possible, and the antenna planning method is best.
3. Set the frequency of the walkie-talkie, press the launch button,
observe the meter reading, and register the meter reading. Then set
the walkie-talkie to other frequency points, let the walkie-talkie enter
the launch state again, observe the meter reading and then
compare the readings of each frequency point! You can know the
best frequency/segment of the antenna under test!
A typical field-strength meter is shown in Figure 1. This is a simple
passive (unpowered) circuit in which radio frequency energy is
intercepted by the antenna, rectified to DC, and then used to directly
drive the meter. The maximum sensitivity of this circuit is based
primarily on several factors:
The gain of the antenna: How much of the signal is actually
intercepted.
The sensitivity of the meter movement being used.
The nature of the diodes being used.
