7.9.3. Time Markers / Period
The time marker function allows output signals of fixed periods between 10ns and 10s.
7.9.3.1. Setting the Output
The available time marker outputs are split into 3 ranges:
• 10ns to 5µs
• 10µs to 5ms
• 10ms to 10s
To set an output, first select the range containing the required period from the 3 range buttons. Then
press the time marker button required to set the output.
7.9.3.2. Output Levels
It should be noted that 10µs and above is 2V pk-pk square wave. 5µs and below is 1V pk-pk. Below
50ns, the rise time of the edges is apparent, and at 10ns the output is approximately sinusoidal, but
still 1V pk-pk.
