Configuration with Scream!
The 6TD unit contains a built-in 3-channel digitiser, which can be configured
using Güralp System's Scream! software package.
5.1
Configuring the digitiser
Scream! 4 distinguishes between configuration and control of digitisers. The
most important difference is that a digitiser may be controlled through
Scream! at any time whilst it is acquiring data, whereas configuration options
only take effect after a reboot (with consequent loss of data).
To change the configuration of any connected digitiser:
1. Locate the digitiser you want to configure. All connected digitisers
have an entry in the tree on the left of Scream!'s main window. If the
digitiser is transmitting data through a remote server or EAM, you may
need to “unroll” the entry for that server (by clicking on the icon) to see
the digitisers connected to it.
2. Right-click on the digitiser's entry (not the icon for the server or any
Comxx icon). digitisers are shown with icons depicting a coloured
cylinder ( ).
3. Click Configure…. Scream! will contact the digitiser and retrieve its
current configuration, a process which will take a few seconds. When
this is done, the Configuration dialogue window will be displayed.
4. Once you are happy with any changes you have made in the
Configuration dialogue window, click
to send them to
the digitiser and reboot. This will take a short while.
To control a digitiser whilst it is running, either right-click on the digitiser's
entry in the list and click Control…, or double-click the entry. In either case
Scream! will contact the digitiser to retrieve control information and display
the Control window. The options you can control immediately are:
•
the type of sensor you are using,
•
GPS power cycling options,
•
the short-term and long-term average values for triggering (but not
which streams perform the trigger, or which are output by it) (see
•
the length of pre-trigger and post-trigger periods,
•
calibration signal options, and
•
mass control functions.
