shown. It has two working modes, parameter coupling and waveform combine.
Parameter coupling contains Frequency Coupling and Amplitude Coupling.
5.15.1 Coupling Direction
The dual channels are identical and allowed to be coupled by both of each other. Press
〖Couple Direction〗softkey to set the coupling direction between channels.
If set A to B, A is source channel and B is object channel, vice versa. The direction is one
way to allow the source channel to be coupled to object channel.
Any mode of dual channel once enabled, the indicator of which will be lighted on and tells
user entering into the coupling state. And user only can operate source channel but not
the object channel.
5.15.2 Frequency Coupling
With frequency coupling function, generator can make the dual channel frequency output
relates and generates two multiplied frequency or differenced frequency signal.
(1) Press the 〖Freq Cpl On/Off〗 softkey to turn frequency coupling on, the dual
channels coupled function is enabled. When you change the frequency of source
channel, the frequency of object channel will change along with the source channel
automatically and not allowed to be independently set again. The frequency
relationship between two channels accords with the formula:
Frequency of object channel = frequency of source channel×frequency ratio +
frequency difference
(2) Press 〖Cpl Para〗softkey and enter into the parameter coupling menu. Press 〖Freq
Ratio〗and 〖Freq Diff〗softkey to specify the desired frequency ration and frequency
difference.
(3) Press the 〖Freq Cpl On/Off〗 softkey to turn frequency coupling off, the dual
channels coupled function is disabled and frequency can be set independently for
both of channels.
5.15.3 Amplitude Coupling
Amplitude coupling, which is enabled by the 〖Ampl Cpl On/Off〗 softkey, couples the
amplitude and offset voltage between the channels. When you change the amplitude or
offset of source channel, the amplitude or offset of object channel will change along with
the source channel automatically. Once select Off, the dual channels coupled function is
disabled and amplitude and offset can be set independently for both of channels.
