PhaseStation 53100A User’s Manual V1.04 25-Apr-2022 171
Using STREAM
Because STREAM.EXE performs only phase/frequency stability measurements, its command-line options
are relatively limited. Only one parameter is mandatory: you must specify the hardware driver’s
filename as the first parameter on the command line. Currently, only the TimePod and PhaseStation
drivers are supported, so all
STREAM.EXE command lines must begin as follows:
stream timepod.tll
stream phasestation.tll
Additional options, described below, may be specified as needed.
/serial:<sernum>
When more than one TimePod or PhaseStation is connected to the server PC, you may
need to use the /serial option to associate a given
STREAM.EXE instance with a specific
instrument. Each instance of STREAM.EXE supports only one acquisition at a time, but
you can launch as many instances as desired.
Example:
stream timepod.tll /serial:55908.304876
The command above will launch an instance of STREAM.EXE for use with the TimePod
whose serial number is 55908.304876. All other parameters will assume their default
values, configuring the server to provide phase-difference data on TCP/IP port 9192 at a
rate of 10 readings per second.
/file:<filename>
Specifies the name of a file to which the 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
STREAM.EXE
.
The data written to the file may be ‘followed’ from within TimeLab by selecting
Acquire→Acquire from l ive 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 STREAM.EXE to print a copy of all lines written to the file to the stdout
device (i.e., the DOS console itself).
Example:
stream timepod.tll /notcp /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. 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.
