MANUAL CHANGES - MODEL 3000
Wavetek's
product improvement
program incorporates the latest electronic
developments into these instruments as rapidly as
development and testing
permit
. Due to the time required to document and
print these instruction
manuals, it is not always possible to include the changes in the original
printing . The following schematics and drawings havebeen changed .
DPS2A has replaced DPS2 ; M10W-9 has replaced M10W ; M29--2 has replacedM29-1 ;
M31Ahas replaced M31 ; M32A has replaced M32 ; M41A-1 has replaced
M41A
.
In all
cases where the formerassembly is mentioned in the manual text, the new
assemblyname should be understood . All specifications, adjustments,
and
procedures, havebeenupdatedin themanual text .
GENERAL

Two gaskets are being installed under the M9W and
MlOW-9modules to
further reduce RFI radiation . The hold-down screws
for these modules
are 3/8" instead of 5/16" as for the other modules .
The gasket
materialconsists of nickel fibers imbedded
in a silicone elastomer .
Loose fibers may
penetrate
the
skin or short out a chassisterminal ;
therefore use care when handling the gasket .

M9W to M9W-7
11/14/85 The M9W-7 Sweep Oscillator module replaces the M9W module in the
Model 3000 Signal Generators . The M9W-7 module uses a control
circuit to automatically set the
phased-locked loop voltage in PLL3
to zero . This eliminates the Pot
"D" adjustment in the M9W
module .
Disregardthe first paragraph of Section 5 .3 .7 in
the
manual, since
there is no pot "D" . The M9W-7 parts
list
and
schematicreplace
the
M9W documents maybe
found at the end of the Manual Changes .

Revise the first paragraph beginningwith line 3 to read :
Connect a digitalvoltmeter to M32A PIN 14 . The DVM should read
between +0 .5 and +2 .5 VDC . If the leveler voltage is within this
range, DO NOT adjust the
M30-4t
trimmer capacitors . (The dash number
# depends upon the instrument modelnumber .)
If the leveler voltage
is
not between
+0 .5 and +2 .5 VDC, carefully
adjust trimmers
A and B on top of the M30-# until the voltage is
correct .
