Other capabilities

1. Internal hard disk drive
   Store and recall instrument states, calibration data, and trace data on internal hard drive. Trace data can be saved in CSV (comma separated value) format. Instrument states include all control settings, limit lines, segment sweep tables, and memory trace data.
2. USB
   Instrument states, calibration data, and trace data can be stored on an external USB drive.
3. Screen hardcopy
   Printouts of instrument data are directly produced on a printer. The analyzer provides USB and parallel interfaces.
4. Familiar graphic user interface
   Protek A333 provides graphic user interface based on Windows. There are three ways to operate A333 manually: a hard-key interface, a touch screen interface, mouse interface.
5. Limit lines
   Defining the test limit lines that appear on the display for pass/fail testing. Defined limits may be of any combination of horizontal/sloping lines and discrete data points.
