measurelinear
Computes the slope and intercept coefficients of the current phase-difference chart. After a
measurelinear command has been issued, a subsequent removelinear on command will cause
the linear trendline to be removed from the chart data returned by show phasediff.
If
measurelinear
is executed while
removelinear on
is in effect, the stored coefficients will be
updated for use by subsequent
show phasediff
commands. It is not necessary to use
removelinear off before issuing a measurelinear command.
open <filename>
Opens an ASCII text file to which streaming phase-difference or frequency readings will be
written. If the specified file already exists, it will be overwritten. Typically the file is shared with
other applications that can access it in read-only mode while it’s being written by TSERVE.
The data written to the file may be ‘followed’ from within TimeLab by selecting
Acquire→Acquire from live ASCII file
.
You can also monitor the data written to the file with a
command such as
tail –f <filename>
from Cygwin. Finally, pressing the Scroll Lock key will cause
TSERVE to display the lines written to the file on the stdout device (i.e., the DOS console itself)
at a maximum rate of 10 readings per second.
Example:
tserve64 /data_port:0 /cmd_port:0 /start /format:P /file:%HOMEPATH%\Documents\mydata.txt
The command above writes a continuous stream of phase-difference readings to the file
mydata.txt in the current user’s Documents folder. No TCP/IP ports are opened for either data
streaming or command input. You can then use TimeLab or another application to ‘follow’ the
file. Even if the acquisition fails or otherwise encounters problems, you can use the appropriate
File→Import
option to bring the data into TimeLab at any time.
The output file may be flushed and closed at any time by issuing a close command or by open ing
a different file. In addition to the open command, a stream output file can also be opened at
TSERVE startup time by specifying the
/file: <filename>
command-line option.
