Freezing the image
Once the image is acceptable, you may freeze it instead of
running a test. This feature allows you to keep the current view
and to store it for future reference. In Freeze mode, the picture
has a blue colored frame.

J
Press the QuickCapture™ key (if it is set to Freeze mode).
– or –
Press the [
A
] key and tap the [ Freeze ] button.
To return to the live image:
J
Press the QuickCapture™ key.

Background
Every saving covers the complete image and overlay data
available, regardless of the current screen contents:
• Two JPEG files for high and low magnification
• One XML file for test result description
• One PGM file (compressed) for failed locations
• One container file
When data is requested by the user (e.g. using SCPI), the
provided jpg-file is created just in time by the software. This
concept helps to save memory space and allows to maintain
sharp zone rings for all resolutions (VGA, QVGA and QQVGA).
