N0 MOD
Disconnect B002
(PB-100) and
connect DC ammeter
to TP8(+) & TP7(— )
VR 9
Adjust so that DC ampere-
meter indication is 65 mA.
If this is not met, set VR9
to MAX.
2
DITTO
Connect DC ammeter
to TP8(+) & TP6(-)
VR8
Adjust so that DC ampere—
meter indication is 30 mA.
3
USB
19 CH
MOD IN
Remove DC ammeter
& connect В002
(PB-100). Connect
Powermeter, -
RF VTVM and
oscilloscope to
ANT JACK. (J501)
L34, 35,
36, 37,
& 14
Adjust to MAX the RF Volt
meter indication.
However,
adjust MOD input so that
