The LEVEL event occures when the specified voltage is reached on the specified slope of the input
signal. The LEVEL trigger event or sample event can only be used for DC voltage or direct-sampled
measurements.
2
The output buffer must be empty and reading memory must be OFF or empty for the SYN event to occur.
3
The input buffer must be enabled or you must suppress cr lf when sending the TARM SGL command.
