The same structure can be repeated for the different pulse
durations for each frequency. When you save the calibration file,
create a file name that includes the current date and the current
output power. Save the information as a TXT file. Example:
....\0.256msec\cal010603-2000w.txt
While the calibration takes place, we recommend that you also
collect a raw data file. Browse the file directory in the Store
dialogue box to locate the correct directory. The raw data file
name will be generated automatically, but you may specify a
prefix. The raw data file is used for replay.
The same procedure can be repeated for each of the installed
frequencies.
