Channel synchronization (from firmware 10)

Channel synchronization (from firmware10)

From EL2502 FW10 a setting is available in the CoE that makes the output of channel 2 directly dependent on the settings of channel 1.

Function:

• No: no dependence of channel 2 on channel 1
• Ch2 = Ch1: Frequency and duty factor of channel 1 are also applied to channel 2.
  The phase angle is 0, i.e. the rising/falling edges of channels 1 and 2 arrive at the same time and channel 2 outputs the same as channel 1.
• Ch2 = Ch1 inverted: Frequency and duty factor of channel 1 are also applied to channel 2, but the duty factor is inverted.
  The phase angle is 0, i.e. a rising edge of channel 1 arrives at the same time as a falling edge of channel 2 etc.

Notes

• The ChannelSynchronisation setting is also present in channel 2, but has no effect there or rather is not to be used.
• On activating or deactivating the function in the CoE, an invalid phase angle briefly occurs (naturally) on channel 2.

Example: As soon as “Ch2 = Ch1” is activated (visualized here for triggering the oscilloscope by the additional channel Trig) there is a brief pause on channel 2 until the synchronization takes effect.
