Channel mode selection (CHANNEL MODE)
Selecting the operating modes for channels 1 and 2 are described.
Definitions:
INDEP (independent 2 channel) : CH1 and CH2 operate independently.
2 PHASE : CH1 and CH2 operate at the same frequency.
Example:
CH1 1 kHz 10 kHz
CH2 1 kHz 10 kHz
Frequency sweep and frequency modulation settings and operation
are also the same for CH1 and CH2.
2 TONE (fixed frequency difference) : CH1 and CH2 operate continuously at a fixed frequency
difference.
Example:
CH1 1 kHz 10 kHz
CH2 2 kHz 11 kHz
Frequency sweep and frequency modulation settings are at the
fixed frequency difference.
RATIO (fixed frequency ratio) : CH1 and CH2 operate continuously at a fixed frequency ratio.
Example:
CH1 1 kHz 10 kHz
CH2 2 kHz 20 kHz
Frequency sweep and frequency modulation settings are at the
fixed frequency ratio.
DIFF (differential output) : CH1 and CH2 operate at the same frequency, amplitude and DC
offset, but at opposite waveforms (reverse phase).
In this mode, amplitude, DC offset, output range, output on/off,
phase, frequency sweep and frequency modulation settings are
copied from CH1 to CH2.
