Metrozet Software and Tools

Metrozet has developed tools for analyzing data generated by its VBB sensor products.
These tools allow accurate calibration and prediction of sensor response parameters
(poles and zeros, and scalar responsivity).

CALEX-EW Download

CALEX-EW is a time domain conjugate gradient filtering method that calculates 2nd order response parameters
(and poles/zeros) from ASCII data. It is designed for use with the STS1-E300 and M2166-VBB products,
operating in their "velocity SWEEP" calibration mode.

CALEX-MZ Download

CALEX-MZ is an enhanced version of CALEX-EW that performs time domain fitting of ASCII calibration data from either
the M2166-VBB or STS1-E300 products. CALEX-MZ has added options (4th and 6th order fits)to allow more accurate
determination of the sensor's upper corner frequency.

CALEX-MZ-MSEED Download

A version of CALEX-MZ that works with Mini-SEED files containing sensor calibration data.
