Note: The signal used as the Reference signal needs to be the one that has suffered the smaller
delay. If that is the Input 2 signal, then you need to swap over the two inputs.
You can readily tell if you need to swap by calling up the PQA Meters display described in
Section S.4: if the Video Delay line of this display shows a negative value, the signal on Input 1
is lagging behind the signal on Input 2 and the two signals need to be swapped.
The steps used are as follows:
Control Panel Mouse & Keyboard
Step 1: Select External/External Mode
Select External/External from the drop down Mode menu on the PQA Toolbar.
Step 2: Feed the signals into SDI In 1 and SDI In 2
Step 3: Check if Input 1 is in advance of Input 2 or the other way round, and switch if necessary
1. Check the value shown under Frames in the PQA Toolbar.
2. If a negative number of frames is shown, swap the inputs.
