10.1 Frequency Response for 120 s and 20 s models
The following sections provide frequency response information for Trillium Compact
seismometers.
You can obtain response files from the following sources:
l
From Nanometrics' customer support site at http://support.nanometrics.ca .
l
From the IRIS DMC Library of Nominal Responses for Seismic Instruments at
http://ds.iris.edu/NRL/ .
Figure 10-1 is a bode plot that shows the nominal ground motion response for Trillium
Compact seismometers. The amplitude response to calibration input signals is nearly identical
to that for ground motion. The phase response is slightly different at higher frequencies.
