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

as source channel or target channel, press

〖

Direction

〗

soft key to switch.

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

〖

TargetChannel

〗

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

keys

〖

CH2

〗

and

〖

CH3

〗

and they are highlighted to mean they are chosen. Press the s

oft key

〖

CH2

〗

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
