Sync/BlazeX
The rear panel BlazeX output BNC can be configured to output a reference frequency
sync signal (either bipolar or unipolar square sync) or a low-latency X output (for closed
loop applications at short time constants).
File Settings
Data and screenshots can be saved to a USB memory stick inserted into the front panel.
Press the [Save] button to save all the data values currently plotted on the strip chart.
Press the [Screen Shot] button to save an image of the screen. The memory stick must be
formatted as FAT32, and the saved files can be read by Windows and Macintosh
computers.
Folder
Navigate to the destination folder on the memory stick. New files will be saved in the
destination folder.
The subdirectories in the current destination folder are listed. Use the {↑} and {↓} buttons
in this section to scroll the list of subdirectories. Touch a {subdirectory} to select it as the
destination. Touch {..} to go up one directory level. Repeat until the desired directory is
selected.
Prefix and Suffix
File names are generated from the Prefix string and the Suffix number. The Next File
Name is shown. The suffix number is automatically incremented after every file save.
The extension is .BMP for screenshots and either .CSV or .MAT for data files.
File names must conform to the 8.3 format so the length of Prefix plus the length of the
Suffix is limited to an 8 character string.
Enter an alphanumeric prefix string and a numeric suffix.
Print Mode
Pressing [Screen Shot] saves a screen shot to the memory stick as a .BMP file. Set the
Print Mode to Screen, Print or Monochrome. Screen is an exact screen shot, Print
replaces the black background with white and Monochrome is black and white.
Format
Determines the format of the data files that are produced when the [Save] button is
pressed. Has no effect on screenshots. Format can be set to .CSV (comma-delimited
ASCII text file) or .MAT (Matlab binary file).
