7.6.2 Modulation conditions
■ FM
Carrier waveform Standard waveform other than noise, pulse wave and
DC, and arbitrary waveform
Peak deviation setting range 0.00 µHz to less than 15 MHz (8 digits or 0.01 µHz
resolution)
■ FSK
Carrier waveform Standard waveform other than noise, pulse wave and
DC, and arbitrary waveform
Hop frequency setting range Within settable carrier waveform frequency range
(8 digits or 0.01 µHz resolution)
■ PM
Carrier waveform Standard waveform other than noise and DC, and
arbitrary waveform
Peak deviation setting range 0.000° to 180.000° (0.001° resolution)
■ PSK
Carrier waveform Standard waveform other than noise and DC, and
arbitrary waveform
Deviation setting range −1800.00° to +1800.000° (0.001° resolution)
Remark The sine wave amplitude frequency characteristics
during PSK are limited to 25 MHz, −3 dB.
■ AM (non-DSB-SC)
Carrier waveform Standard waveform other than DC, and arbitrary
waveform
Modulation depth setting range 0.0% to 100.0% (0.1% resolution)
Remark When the modulation depth is 0%, the amplitude is 1/2
of the set value.
■ AM (DSB-SC) (Double Side Band - Suppressed Carrier)
Carrier waveform Standard waveform other than DC, and arbitrary
waveform
Modulation depth setting range 0.0% to 100.0% (0.1% resolution)
Remark When the modulation depth is 100%, the maximum
amplitude is equal to the set value.
During DSB-SC, the carrier frequency component is
zero.
■ DC offset modulation
Carrier waveform Standard waveform and arbitrary waveform
Peak deviation setting range 0 V to 10 V/open
■ PWM
Carrier waveform Square wave, pulse wave
Peak deviation setting range
Square wave
Normal variable duty range 0.0000% to 49.9900% (0.0001% resolution)
