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 µ Hz to less than 15 MHz (8 digits or 0.01 µ Hz
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
µ
Hz 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)
