Below is some model-specific information to help you locate your instrument response.

MBB-1

This sensor measures ground velocity.

MBB-2

This sensor measures ground velocity.

PBB-200S Horizontal

This sensor measures ground velocity. Poles and zeros differ between horizontal and vertical components

PBB-200S Vertical

This sensor measures ground velocity. Poles and zeros differ between horizontal and vertical components

TSA-100S

This sensor measures ground acceleration.

TSA-SMA

This strong motion accelerometer is the onboard sensor for the TSA-SMA accelerograph. The only response information available for this sensor was the number of poles and zeros, the A0 normalization factor, and sensitivity. The pole values have been adopted from the TSA-100S, the zero was dropped, and the complex conjugate pole pair for the feedback electronics was adjusted to fit the available information. This is the best estimate to the fit the information available, but small differences above 100 Hz can't be ruled out.
