Vertex Standard VX-6000V Service Manual page 19

Before beginning, connect the transceiver and PC
using the FIF-12 USB Programming Interface and
T9101628 Connection Cable, then download the EE-
PROM data from the transceiver to the computer.
Store this data in a disk file so that it can be saved
and retrieved later. Using the table below, program
the channel, CTCSS, and DCS alignment settings for
your transceiver version. Upload this file to the trans-
ceiver.
Note: Signal levels in dB referred to in this proce-
dure are based on 0 dBμ = 0.5 μV (closed cir-
cuit).

PLL & Transmitter
Set up the test equipment as shown for transmit-
ter alignment.
Maintain the supply voltage at 13.4 V DC for all
steps.
PLL VCV
 Connect the positive lead of the DC voltmeter to
test point TP1008 (VCV) on the Main Unit, as in-
dicated in the figure, and connect the negative lead
to chassis ground.
 Set the transceiver to the low band edge frequency
channel (CH1 or CH4), then adjust TC1001 on the
Main Unit for 1.6 V ± 0.1 V on the voltmeter.
 Key the transmitter, and adjust TC1002 on the
Main Unit for 1.85 V ±0.1 V on the voltmeter.
 Next select to the high edge frequency channel
(CH3 or CH6) and confirm the VCV is less than
7.0 V on the voltmeter.
 Key the transmitter, and confirm the VCV is less
than 7.0 V on the voltmeter.
