GÜRALP MOD DM24 DIGITIZER


1 "SCREAM" SOFTWARE


Ref email dated 24.11.2017:

"Güralp have released version 4.6 of the "Scream" acquisition software, and version 3 of the ART strong motion analysis package. Scream is available for both Windows (all versions from Windows 98 onwards) and Linux. ART, however, is only available on Windows. There are a number of changes since 4.5 and a list is available on the web site at www.guralp.com/sw/scream4.6.shtml

All users are recommended to uninstall previous versions, and install one of the downloads below.

You can download the installer for Windows (all versions) at:

2 GÜRALP MOD. CMG-DM24-S3 DIGITIZER


2.1 Change gain on CMG-DM24-S3 digitizer


By: O.M.
Date: 16 August 2010

To change gain (sensitivity) of a digitizer to 4 times than standard i.e. changing from 3.2 uV to 0.8 uV, following resistors on ADC board (ASE-ARM-0004 Issue C) need to be changed:

 R4   from 1.69 kOhm   to 51 kOhm
 R3   ------------ " ------------
 R10  ------------ " ------------
 R9   ------------ " ------------
 R16  ------------ " ------------
 R15  ------------ " ------------
 R73  ------------ " ------------
 R72  ------------ " ------------

Ref. original description (also including how to change sensitivity to 10x normal).

New SMD resistor specifications:

Resistors R4, R3, R10, R9 marked.
Resistors R4, R3, R10, R9 marked.
Resistors R16, R15, R73, R72 marked
Resistors R16, R15, R73, R72 marked.
