Elimination Of Undesired Signal Components - Kenwood CS-3025 Instruction Manual

ELIMINATION OF UNDESIRED SIGNAL COMPONENTS

The A D D feature can be conveniently used to cancel out the effect of an undesired signal
component which superimposed on the signal you w i s h to observe.
Procedure:
1 . Apply the signal containing an undesired component to the C H 1 INPUT jack and the
undesired signal itself alone to the C H 2 INPUT jack.
2. Set the V or Y MODE to C H O P and S O U R C E to C H 2 . Verify that C H 2 represents the
unwanted signal in reverse polarity. If necessary reverse polarity by setting C H 2 to INV.
3 . Set the V or Y MODE to A D D and C H 2 V O L T S / D I V and V A R I A B L E so that the undesired
signal component is cancelled a s much as possible. T h e remaining signal should be the
signal y o u w i s h to observe alone and free of the unwanted signal.
