ot be used as source channels. For 2-channel model, both CH1 and CH2 could be used
as source channel or target channel, press

3.18.3 Coupling Mode
Press
〖
Mode
〗
soft key to enter the coupling mode selection menu, You can select four c
oupling modes, which could be valid at the same time. This setting is not available to 2-
channel model.
3.18.4 Target Channel
Press
〖

〗
soft key to enter the channel selection menu and select the targ
et channel of the current mode. For example, if current model is ‘mode 1’, press the soft

again and it’s highlight disappear to mean CH2 is removed, and the chos
en target channel is shown in the display area. Because CH3 has been selected as the tar
get channel in ‘mode 1’, it cannot be selected as the target channel again in other modes.
The setting is not available for 2-channel model.
3.18.5 Frequency Coupling
With frequency coupling function, generator can make frequency output of channels relates and
generates multiplied frequency or differenced frequency signal. Press
〖
FreqCpl
〗
soft key to set
the frequency coupling to ‘On’, and the frequency value between channels shall comply with the
following formula.
Target channel’s frequency= Source channel’s frequency×frequency ratio+ frequency difference
When using the frequency coupling function, if the frequency of the target channel exceeds the
frequency upper or lower limit, the instrument will set the frequency to the limit value and the
above formula is no longer applied to.
3.18.6 Amplitude Coupling
Amplitude coupling enables the output amplitude between channels related and output differential
signal. Press
〖
AmplCpl
〗
soft key and set the amplitude coupling to ‘On’, and the amplitude or
offset value of the two channels shall comply with the following formula:
Target channel amplitude= Source channel am amplitude difference
Target channel offset= Source channel offset deviation
