A Notepad or text
fi
le should appear with the data. Depending on the time
between clicking Start and Stop, you may have several thousand lines. If you
used tab delimited text, you should be able to copy and paste portions of this
fi
le directly into a Microsoft Excel spreadsheet. You should see the icon for the
fi
le on your desktop and the name of the
fi
le should include the date and time.
Troubleshooting
Memory Errors
This application can generate a large amount of data and can consume signi
fi
cant
amounts of memory and disk space. This can cause two problems. This will
probably be because the text
fi
le written during measurements is too large for the
application trying to display the
fi
le (probably NotePad) if you are running as
fast as possible. You can assume that text will be generated at 100 kB/s for CW
measurements, and 250 kB/s for pulse measurements. If your computer runs
out of RAM or disk space, this may also cause a problem. Each measured point
requires (roughly) 54 bytes. If there is not suf
fi
cient memory (RAM) and you do
not reduce memory usage, you could run out of RAM.
To address either problem, reduce the reading rate using the
Meas Spacing
settings. For text
fi
les, you can also reduce the duration of the test run by
adjusting the
Meas Start
and
Meas Stop
setting, or deselect the
View Data upon
Completion
check box.
