7.12 2-channel ganged operation (FG420 only)
Channel modes
Channel Mode Operation
Independent Independent setting
2-phase Holds same frequency. During frequency sweep, internal frequency modulation,
and internal FSK, the same frequency is controlled to be held.
External frequency modulation and external FSK are not possible.
Phase independently set for each channel.
Constant frequency
difference
Holds the frequency difference as a constant value.
During frequency sweep, internal frequency modulation, and internal FSK, the
frequency difference is controlled to be held.
External frequency modulation and external FSK are not possible.
Constant frequency ratio Holds the frequency ratio as a constant value.
During frequency sweep, internal frequency modulation, and internal FSK, the
frequency ratio is controlled to be held.
External frequency modulation and external FSK are not possible.
Differential output Same frequency, amplitude, and DC offset. Reverse phase waveform.
Differential output is controlled to be held during all types of sweep and
internal modulation.
External modulation and external addition are not possible.
Common limiting conditions during 2-phase, constant frequency difference, constant frequency ratio,
and differential output
· Oscillation in same oscillation mode (also same modulation type during modulated oscillation,
and same sweep type during sweep oscillation)
· Applicable to standard waveform other than noise and DC, and arbitrary waveform
· Burst, gated single-shot sweep not possible
Same value setting, same manipulation
Yes
Frequency difference setting range 0.00
μ
Hz to less than 30 MHz (0.01
μ
Hz resolution)
CH2 frequency - CH1 frequency
Frequency ratio N:M setting range 1 to 9,999,999 (for each of N and M)
N:M = CH2 frequency:CH1 frequency
Phase synchronization Automatically executed during channel mode switching
Time difference between channels during 2-phase
*1
±20 ns or less (±10 ns or less typ.)
Condition: Same waveform (sine or square)
