  ● Setting frequency:  Set frequency for data input in the following timing.
Free:     Shift frequency at data input.
Rise Trig: Shift frequency at rising edge of external clock.
Fall Trig: Shift frequency at falling edge of external clock.
  ● Baseband filter:  Following filters can be used to pass signal.
Filter type:  10th-order Besser filter
Cutoff frequency:  100Hz to 30kHz(-3dB)
Set resolution:  Upper 2 digits
  ● FM deviation accuracy:  Same as that of MG3641A/MG3642A, with restriction of no baseband filter (by-passed)
  ● External modulation signal input
