Wavetek 3000 Instruction Manual page 213

INTRODUCTION
Option 7 provides for a reduction in RF leakage such that
less than 0.1 pV is .induced in a two-turn, one inch diameter
loop (feeding a 5012 receiver) held one inch away from any
surface, when the instrument is developing 30 mVRMS or
less into a 50 Q termination .
An alternate method of detection is to place a paging
receiver with .2 pV sensitivity (such as Motorola A04FNC
in a TEK-69 fixture connected to the instrument RF OUT
connector) 6 inches in front of the instrument with the
instrument
OUTPUT STEP ATTENUATOR set
at
minimum and the instrument frequency set to that of
the paging receiver .
The paging receiver IF test point is monitored with an AC
voltmeter, and should change less than 0.5 dB .
OPERATION
There is no change in operation from the standard
instrument.
CIRCUIT DESCRIPTION
For Option 7, the standard M9W Sweep Oscillator is
replaced with an M9W-2. The operation of the M9W-2 is
identical to the M9W; the difference is additional shielding
and filtering in the M9W-2.
Also, additional shielding,
filtering for the PROGRAMMING jack inputs, filtering for
the LEVEL PROGRAM jack inputs (for Option 1A), and
an AC line filter are added to the rear panel of the
instrument .
MAINTENANCE
NOTE
OPTION 7
LOW LEAKAGE
If Option 4, Auxilliary RF Output, is also installed, the
Sweep Oscillator is an M9W-3.
No calibration or maintenance should be required for this
option other than that described in previous sections of
this manual .
