(When the set frequency is 1 GHz or less, response time from final command to ±100 Hz)
When Frequency changing speed = Normal:
≤40 ms (When going by 3 GHz)
≤15 ms (When the amount of frequency change is less than 1 GHz without going by 3 GHz)
≤20 ms (When the amount of frequency change is 1 GHz or more without going by 3 GHz)
Switching time When Frequency changing speed = Fast:
≤40 ms (When going by 3 GHz)
≤10 ms (When not going by 3 GHz)
With Mechanical Attenuator Option
Regardless of frequency changing speed.:
≤100 ms (When going by 3 GHz)
≤80 ms (When not going by 3 GHz)
Direct setup: The absolute value of frequency is set up and displayed.
Frequency setup and Display
Setup by CH: CH is assigned to frequency. Separate CH tables can be assigned to two or more
systems (groups). Group names and CH numbers are set and displayed. Furthermore, the
corresponding frequency is displayed simultaneously.
