Updating the Beaglehole Instruments Control Software
NOTE: If you have not updated your Beaglehole Instruments software in a while,
you may find that a number of things have changed after installing this
update. If your Measurement Controller does not support the 'Sampling
factor' data aquisition scheme yet, you should adjust your configuration to
improve the performance of the ellipsometer. This is described below.
NOTE: This update contains the Beaglehole Instruments ellipsometry analysis
system for analysing spectroscopic and variable angle measurements
of multilayer samples. This software is described in the separate
'Analysis Manual', available from Beaglehole Instruments.
NOTE: This update fixes a significant issue with the data display of the
Beaglehole Instruments ellipsometry analysis system.
NOTE: This release of Beaglehole Instruments Igor procedures requires
Igor 4.07 or later!
NOTE: This archive is for updating an existing installation. An installation
CD for the Beaglehole Instruments control software is supplied with
Before beginning installation please read the license conditions contained
within the file "LICENSE.TXT". Installation of this software indicates
acceptance of the license terms set forth within that file.
Please read this carefully before installing.
Notes for this release can be found in the file "history_01apr03.txt".
List of files:
LICENCE.TXT Conditions of use of the software. Please read this.
User Procedures A folder containing a number of Igor procedure files
which make up the Igor software interface.
Materials A folder containing material definition files for use
with the ellipsometry analysis system.
bictrl_update_2.33.1.pxp An Igor experiment containing an installer for the
latest version of the Measurement Controller operating

readme_update_22may03.txt This file.
manual_supplement_15may03.pdf An electronic document in PDF format that describes
the new features added by this software release.
It uses the same format as the BI manuals and can
be printed to supplement existing printed manuals.
1) Update Igor Pro on your system to the latest release (version 4.07 at the
time of this writing). The updater can be downloaded from the Wavemetrics
web site at http://www.wavemetrics.com.
2) Make sure that Igor is not running.
3) Copy all the files in the 'User Procedures' folder to
C:\Program Files\WaveMetrics\Igor Pro Folder\User Procedures
When asked if you want to overwrite the existing files with the newer
ones, click 'Yes to all'.
4) If you want to use the ellipsometry analysis system and haven't used it before, copy
the folder named "Materials" into the "Beaglehole Instruments" folder inside the
"Igor Pro Folder".
5) Start Igor.
6) Load the Igor experiment file 'bictrl_update_2.33.1.pxp' and follow the instructions
in the experiment to update the Measurement Controller software.
If you have problems with the update, please contact Beaglehole Instruments at
Adjusting the Measurement Controller configuration:
If you have a Picometer Ellipsometer, and your system did not have the 'Sampling factor'
data acquisition scheme installed before this update, you should adjust the instrument
configuration to get the best performance from ellipsometry measurements. The 'Sampling
Factor' setting controls a new method of averaging multiple readings of the data acquisition
hardware, resulting in lower noise. The method is described in detail in the manual supplement
In order to set up the signal averaging, open the Controller Configuration panel from
the 'bi' menu after you have finished the update installation process. In the 'Picometer'
section of the panel, set the 'Sampling factor' value to 2. The 'Lock-in wait factor' should
be set to 4.
In addition, it should be checked that the block averaging for individual analog input
channels is set to 1. The block averaging scheme is superseded by the sampling factor scheme.
In order to do this, open the Controller Configuration (as above) and do the following:
- In the device section in the center of the panel, select 'ADC' from the popup menu.
- In the 'unit' field of the 'ADC' section, enter '4' and hit 'Return' (this is the
input channel for the DC signal).
- In the 'averaging' field, enter '1' and hit return.
- Click the 'send' button underneath the 'averaging' field.
- Repeat the above steps for units 7 and 8 (the lock-in readout channels).
- Click the 'Save Config' button at the bottom of the Controller Configuration panel.
Note that a 'Sampling factor' setting larger than zero increases the measurement time
by the lock-in integration time times the sampling factor setting. This is explained
in more detail in the manual supplement that is part of this software update.
Please report any bugs in the software to email@example.com. We can only fix them if
we know about them! We also appreciate positive and negative feedback on any aspect of
