Memory depth

VM-SCOPE stores 10 million samples per channel. The use of this memory can be controlled in the Memory depth menu. If, for example, 40 kHz bandwidth are needed, VM-SCOPE will store about 100,000 samples per second. We assume that the measuring time is 10 seconds which results in 1 million samples. If VM-SCOPE averages 10 measurements the memory of 10 million samples will be filled completely.

Maximum signal frequency

1. Maximum signal frequency
This is the highest frequency for the band filter. The band filter can always be set to lower frequencies. VM-SCOPE ensures that the signal will always be free of aliasing effects.

Maximum posttrigger time

2. Maximum posttrigger time
The maximum duration of measurement starting at the trigger event. It can always be set to lower values during measurement.

Maximum number of averages

3. Maximum number of averages
Maximum number of averaged measurements.  It can always be set to lower values during measurement (only oscilloscope mode).

Confirm settings

4. Confirm settings
After making above settings click this button to check whether the available memory is sufficient. Measurement cannot be started before confirmation.
