Connection:

Setting of the pulse generator (setting of

superimposed pulse)

Adjustment:

1. Setting of SSG

Receiving frequency : 999 kHz

Percentage modulation : 30%

Modulation frequency : 400 Hz

Antenna input : 74 dBuV (EMF)

2. Set the system as shown in 1., then tune to a

radio station.

3.Superimpose the pulse over signal to set

modulation of SSG to OFF.

4. Use a noise meter to monitor output. Adjust

VR201 to minimize the noise level.
