Independent Mode
When changing the frequency, neither channels‘ DDS resets and the phase deviation between CH1 and CH2 changes at random.
When the independent mode is enabled, the phase parameter cannot be modified and the menu
Phase
is hidden, as shown in
Figure 89.

7.10. OVERVOLTAGE PROTECTION
Choose
[Utility] → [Page 2/2] → [OverVoltage Protection]
to turn on or off the function, as shown in the following figure 90.
Figure 90: Overvoltage Protection Interface
If the state is set to ON, overvoltage protection of CH1 and CH2 will take effect once any of the following conditions is met. When
overvoltage protection occurs, a message will be displayed and the output is disabled.
The absolute value of input voltage is higher than 11 V ± 0.5 V when the amplitude of the generator is higher than or equal to
2 Vpp or the DC offset is higher than or equal to |3 VDC|.
The absolute value of input voltage is higher than 4 V ± 0.5 V when the amplitude of the generator is lower than 2 Vpp or the
DC offset is lower than |3 VDC|.
