Rules for settings
1. Digital input 4 and digital output 4 are used internally for synchronization. Both channels
should be set to inactive. Set Value source to Manual value for digital output 4.
2. Manual configuration amendments to a "slave" require subsequent amendments to the
"master" to avoid the handshake becoming incompatible.
3. If no external Trigger signal is used, the time period (of "master") must be set higher
than the natural cycle (Recording time + Calculation time + 2 x Measured data transmit ti­
me) to avoid the handshake becoming incompatible. See timing diagram.
Procedure
The outcome of synchronization: Triggering takes place (almost) simultaneously. Measure­
ment data (time signal / frequency spectrum) are transmitted one after the other
