to the sample clock frequency and start phase of the master signal.
You can still program each module with some commands and retain
lock position however, some operations require that you repeat the
lock-in sequence as shown above. In the following you'll find a list of
operations that will not interfere with synchronization:
1. Changing output state on/off
2. Changing sync output state on/off
3. Changing sync validation bit/lcom
4. Modifying amplitude and offset
5. Modifying sample clock frequency
In the following you'll find a list of operations that will interfere with
synchronization:
1. Changing waveform type fix/user/sequence
2. Downloading waveforms
3. Modifying sync position and width
4. Modifying trigger burst count, phase and advance source
5. Modifying phase offset between instruments
6. Modifying frequency setting in fixed waveforms mode
