Yaesu FTH-2009, Service Manual

Page: 35 / 39

T he FTH- 2009 has been aligned at the
fact
o
ry for the specified performance
across the frequency range specified for
each version. Realignment should therefore
not be necessary except in the event of a
component failure, or alteration of version.
All component replacement and service
should be performed only by an authorized
Yaesu representive, or the warranty policy
may be voided .
The following test equipment is required
for alignment:
RF Signal Generator:
calib rated output level at 200 MHz
Deviation M eter (linear detector)
Oscilloscope
AF Milivoltmeter
S INAD Meter
I nline Wattmeter: 200 MHz
Regulated DC Power Supply :
adj ustable from 4 to 17V, 2A
50-ohm Non- reactive Dummy Load : lOW at
1 50 MHz
F requency Counter:
+/-0. 2ppm accuracy at 1 50 MHz
AF signal Generator
DC Voltmeter: 10-megohm impedance
Before beginning alignment, we recommend
replacing the customer' s Matrix U nit with
· one preprogrammed with the alignment
frequencies for the corresponding version,
as shown in the following tables . Other­
wise, it will be necessary to make note of
all diode locations for the customers chan­
nel frequencies, and to temporarily replace
them with the alignment frequencies in the
table.
