Setting a Reading Threshold in Memory
The following command allows you to set a reading threshold in the counter's
volatile memory:
DATA:POINts:EVENt:THReshold <count>
DATA:POINts:EVENt:THReshold?
- when
Threshold) in the Standard Operation Register is set to '1'. By monitoring this bit,
readings can be transferred from memory to the output buffer once a given
number of measurements have occurred.
Once the threshold is reached, the number of readings in memory must drop
below the threshold level in order to detect when the threshold is reached again.
Memory Threshold Example
This program sets up the counter to take 1,250,000 readings. Because volatile
reading memory capacity is 1,000,000 readings, readings will be over-written
(memory overflow) if data is not retrieved before memory fills. To prevent memory
overflow, a reading threshold is set and monitored. When the number of readings
in memory reaches the threshold, all readings in memory at that time are
retrieved.
