Example
Assume the following:
¦
Input to
¦
Sample Time is set to 10 seconds and Number of Samples is set to
collect 30 points.
¦
Trigger Channel is set to 21 (hardware threshold triggering).
¦
Trigger Threshold is set to 1.0 and Trigger Type is set to 2 (trigger on
rising edge).
The CBL will collect and store a sample every 10 seconds. The recorded
time for each sample will be 10 seconds. The trigger event (signal rising
through 1.0 Volts) occurs 1.5 seconds after the previous sample, so a
sample collected at the trigger point is taken and stored with a recorded
time of 1.5. The next sample is taken 10 seconds after the trigger sample,
not 8.5 seconds later as would have happened if the internal sample
clock had not been reset.
The Record Time returned (around the trigger point) will be the list:
{...10,10,10,1.5,10,10,...}.
CH1 , set to measure ±10 Volts, is a 0.01 Hz sine wave.
