③ Carrier frequency
Refer to AM-carrier frequency.
④ Modulating wave
Refer to AM-m
⑤ Set modulating frequency
Set the frequency of modulation wave, the range can set to 2 mHz～50 kHz(the default is 100Hz). After
FM function is enabled, the default frequency100 Hz will appeared. The frequency value can adjust by
using Multipurpose knob or numeric keyboard.
⑥ Set frequency offset
Frequency offset represents the deviation of the frequency of the FM modulated waveform relative to
the carrier frequency. The FM frequency offset can be set from the minimum DC to half of the
maximum of the current carrier bandwidth, and the system default frequency offset is 100 Hz. The
frequency value can adjust by using Multipurpose knob or numeric keyboard.
Frequency offset ≤ carrier frequency. If the frequency value is greater than the carrier frequency value,

the instrument will automatically limit the offset to the maximum allowed by the current carrier
frequency.
The sum of frequency offset and carrier frequency ≤ the maximum frequency allowed by the current

carrier. If the frequency offset value is set to an invalid value, the instrument will automatically limit
the offset to the maximum allowed by the current carrier frequency.
(3) Output arbitrary wave
This oscilloscope has stored 200 kinds of arbitrary wave, each wave name refer to built-in arbitrary wave
list.
