2. Multiply the injection locking bandwidth by 2 to determine the
minimum PLL bandwidth required to prevent the injection locking from
causing the system to lose lock. (To prevent accuracy degradation, it
may be necessary to increase the PLL bandwidth to 4 X the injection
locking bandwidth. The computer will inform you during the
measurement if the possibility of accuracy degradation exists.)
3. Locate the required PLL bandwidth in
required for the measurement. (For details on increasing the PTR, refer
to Changing the PTR in this section.
