can read and send the time to the instrument. By sending this event tag to several units, you can
create a common event tag to align all BBR records.
Method 3- Send a digital pulse into a digital input pin on the rear of the power supply (see Digital
Input). This digital pulse will be detected and can be setup to trigger a user-defined status bit. See
Using Expression Signal Routing. All status bits, including the user-defined status bit, are recorded in
the BBR log. This will locate the pulse to within 10 ms, as the BBR is logged every 10 ms (or 100 ms).
By sending this pulse into several units, you can create a common event tag to align all BBR records.
Of course, you can combine these last two methods and also tag the digital pulse with a text message
in the log to record the meaning of that particular pulse.
