OPERATION
3-1-59
Fig. 3-1-51 Normal signal generator level control operation
Fig. 3-1-52 Extended hysteresis operation with an RF level of -9 dBm as the starting level
Note...
In the hysteresis range the RF level is set in a different way to the normal operation and
this will affect some performance aspects. AM distortion and accuracy will be affected.
With no AM selected, the effect on RF accuracy in the +HYST region will be relatively
minor. But the effect in the -HYST region on RF level accuracy will be more significant.
