e.g. Recording time set to 0.5 ms

e.g. Recording time set to 5ms

Setting the trigger point manually

Pundit Link gives the user the option to set the trigger point manually. See the example
below.

Trigger point capture automatically.

Zoom in by clicking on the time and amplitude scale zoom buttons for fine adjustment.

Click and drag the blue line to adjust the trigger point manually.

Note:

In this example the signal amplitude is very low. Use higher output voltage

settings and gain settings for better results.

Data Logging

The Data Logging mode allows the user to program a test sequence.

Interval – between measurements.

Number of events – until the test is
completed.

Readings per event – how many
measurements are made in each interval.
