WOPEN
Syntax ROPEN <string>
Description If the specified file exists, this command makes it write-enabled; otherwise, creates a new
file and makes it write-enabled. This command takes its arguments in a different way,
depending on the file format.
The size of an existing file cannot be changed. Therefore, if you want to change them,
delete the file itself using the “PURG”(406page) command and then create a new file using
this command.
This command is used in combination with the “WRITE”(463page) command and the
“CLOSE”(280page) commands, as shown in Figure 16-8 on page 412. (No query)
Parameters
Corresponding
key No front panel key is available to execute this function.
Description
DIVS2 The value obtained by dividing the measurement parameter value
at the marker position by is set as the cutoff point.
MULS2 The value obtained by multiplying the measurement parameter
value at the marker position and is set as the cutoff point.
DIV2 The value obtained by dividing the measurement parameter value
at the marker position by 2 is set as the cutoff point.
FIXed (initial
value) Lets you set the cutoff point freely using the “WIDFVAL”
command on page 460.
