ASin
Inserts the text ASIN( into the math expression.

Inserts the text ATAN( into the math expression.
Auto-Increment file name
1. Select the Auto-increment file name to save numerous similar files without retyping the entire file
name each time.
2. Enter a Base file name.
3. Click Save.
For the initial save the default count is 000, b ut you can overwrite this number if you choose. Your
first file is saved as
[Basefilename][count].ext,whereext is the file extension. On subsequent
saves, the instrument searches for the highest numbered file name and increases the number by one, as
in
Basefilename001.ext.
For example, if you are saving a series of rise time data files, you can use "Risetime" as the base file
name. Your first file is saved as
Risetime000.ext,whereext is the file type extension. The next file
will be
Risetime001.ext, and so on.
TIP. If Count reaches 999, it is suggested that you change the base file name to Basefilename1 (for
example, Risetime1) on the next save. Your next file will then be saved as Risetime1000.ext. You will
receive a warning message if you are going to overwrite any fileswiththesamename.
Auto trigger mode
Auto trigger mode causes the instrument to trigger if a valid trigger event does not occur within a set
amount of time.
Auto trigger m ode is useful w hen probing DC signal levels such as power supplies or logic levels that are
stuck high or low. It is also useful when looking for activities on signal nodes such as oscillations when you
first set up the instrument. The length of time it waits for a trigger event depends on the time base setting.
