Alignment Preparation & Precautions


A 50-ohm RF Dummy load and in-line wattmeter must be
connected to the main antenna jack in all procedures that
call for transmission, except where specified otherwise.
Correct alignment is not possible with an antenna.
After completing one step, read the following step to determine
whether the same test equipment will be required.
If not, remove the test equipment (except dummy load
and wattmeter, if connected) before proceeding.


Correct alignment requires that the ambient temperature
be the same as that of the transceiver and test equipment,
and that this temperature be held constant between 68 °F~
86°F (20°C ~ 30°C). When the transceiver is brought into
the shop from hot or cold air, it should be allowed time to
come to room temperature before alignment.


Whenever possible, alignments should be made with oscillator
shields and circuit boards firmly affixed in place.
Also, the test equipment must be thoroughly warmed up
before beginning.


Note: Signal levels in dB referred to in this procedure are
based on 0 dBμ = 0.5 μV (closed circuit).

Under no circumstances should any alignment be attempted
unless the normal function and operation of the transceiver
are clearly understood, the cause of the malfunction
has been clearly pinpointed and any faulty components
replaced, and the need for realignment determined
to be absolutely necessary.


The following test equipment (and thorough familiarity
with its correct use) is necessary for complete realignment.
Most steps do not require all of the equipment listed,
but the interactions of some adjustments may require
that more complex adjustments be performed in a sequence.
Do not attempt to perform only a single step unless
it is clearly isolated electrically from all other steps.
Rather, have all test equipment ready before beginning,
and follow all of the steps in a section in the order they
are presented.

Chuwi Hi9. There may be more of them among the Chuwi tablet catalog but none of them do the Hi9 if you’re looking for a game experience of ten. Lightweight, powerful and capable of moving to the most demanding Android market game.

And not that I can not move any game available for tablets but the Hi9 runs under the Nougat version of Android so titles like the Tom Clancy’s ShadowBreak or Real Racing 3, will test your hardware but the answer will be perfect.

This is thanks to the combination of two factors: CPU and GPU. In the first one we found a MediaTek with a very high performance and 64 Bit architecture perfect for managing heavy tasks.

The four cores of the MT8173 trigger the performance giving a fluid and very fast response.

When we put the limit to the Hi9 with games like those mentioned above, it is when the PowerVR graphics processor comes into play that everything shines with maximum intensity and the action does not waver at any time.

The GX6250 will be the one that allows the 8.4 “screen to offer us images of maximum purity.

The resolution of 2560 x 1600 pixels show us every detail with maximum precision.And not only in the games, the multimedia experience is also benefited, in this device with 2.5D curved glass that adapts perfectly to our hands.

The dual band Wi-Fi connection, the 4 GB of RAM and the 64 GB storage do nothing but round off the offer.

If we are addicted to downloading and testing all the games that we have and have, your microSD slot up to 128 GB will be a great ally.

On the website of the table Chuwi it is difficult to find a user manual but when they decide to publish them (if they do), we will upload them.
