Alignment
Test Setup
Setup the test equipment as shown for transceiver align-
ment, apply 13.6V DC power to the transceiver. Refer to
the drawings above for Alignment Points.
The transceiver must be programmed for use in the in-
tended system before alignment is attempted. The RF pa-
rameters are loaded from the file during the alignment
process.
In order to facilitate alignment over the complete switch-
ing range of the equipment it is recommended that the
channel data in the transceiver is preset as the chart be-
low.
The Alignment Tool Outline
Installation the tool
Install the CE59 (Clone Editor) to your PC.
The re-alignment for VX-4200/-4100 series may use the
"Alignment" menu of CE59.
Action of the switches
When the transceiver is in alignment mode, the action of
PTT and KEY is ignored. All of the action is remote con-
trolled by PC.
Basic sequence
The data displayed in screen of this tool is temporary data,
and there is fear that the consistence of the displayed data
and the data in the transceiver is failure when you do not
keep the sequence which is specified below.
1. Enter the alignment mode
2. Data upload
3. Align data
4. Data download
When finish the alignment one parameter, the tool ask
you "Update this data?" If you select "Yes," the temporary
data is updated. If you select "Yes," the tool downloaded
data to the transceiver.
Menu of the Tool (BASIC A
LIGNMENT
)
In the Basic Alignment mode, the aligned data written in
the radio will be able to re-align its alignment data. In this
mode, there are many items to align with three point (low
edge, center and high edge) except "VCO," "RX Tune" and
"Mod Balance." The value of each parameter can be
changed to desired position by " " / " " arrow key for
up/down, direct number input and drag the mouse.
To enter the Basic Alignment Mode, select "Basic Align-
ment" in the main menu "Radio." It will start to "Upload"
the written personalized data from the radio and to
"Download" alignment data to the radio. Then pressing
the button "OK" will start the Basic Alignment Mode.
Note; when all items are aligned, it is strongly recommend-
ed to align according to following order. The detail infor-
mation is written in the help of CE59 (Clone Editor).
1. RX VCO Tune Voltage (RX VCO)
2. TX VCO Tune Voltage (TX VCO)
3. PLL Reference Frequency (Frequency)
4. RX Sensitivity (RX Tune)
5. Squelch (SQL)
6. TX Power
7. Modulation Balance <Wide>
8. Modulation Balance <Narrow>
9. Maximum Deviation <Wide>
10. Maximum Deviation <Narrow>
