17.6 Modulated Oscillation Mode
WF1967/WF1968 17-11
17.6 Modulated Oscillation Mode
17.6.1 General
Operation in other oscillation mode Partly possible in the burst and sweep oscillation mode.
Modulation type FM, FSK, PM, PSK, AM, DC offset modulation and PWM
When the sweep function is used simultaneously the
modulation type which overlaps with that of the sweep
type cannot be selected.
Modulation operation Start and stop
Modulation source
Other than FSK, PSK Internal, external (switch)
In addition, CH2 can select the same modulation source as
CH1 (internal only).
When the sweep function is used simultaneously, the
internal modulation source cannot be selected.
FSK, PSK Internal, external (switch)
In addition, CH2 can select the same modulation source as
CH1.
External modulation of FSK and PSK uses an external
trigger input terminal.
When the burst function is used simultaneously, FSK and
PSK cannot be selected in the mode other than auto burst.
Internal modulation waveform
Other than FSK, PSK Sine wave, square wave (duty 50%), triangle wave
(symmetry 50%), rising ramp wave, falling ramp wave,
noise, arbitrary wave
FSK, PSK Square wave (duty 50%)
Noise equivalent bandwidth Select from 100M/30M/10M/3M/1M/300k/100kHz
Internal modulation frequency
Other than FSK, PSK 0.1mHz to 20MHz (resolution 12 digits or 1µHz)
FSK, PSK 0.1mHz to 5MHz (resolution 11 digits or 1µHz)
Internal modulation synchronization output
Output waveform A square wave with duty 50% rising at the zero phase of
the internal modulation waveform
When internal modulation waveform is noise, the level is
fixed to low.
Output connector Shared with synchronization/sub-output connector
(SYNC/SUB OUT).
Internal modulation waveform output
Output voltage -3V to +3V/open
