16
User Manual
 PCI Interface: 32 Bit, 33 MHz.
The full specifications for the Richter16 are provided in section 1.2.1.
ASC’s InSite Seismic Processor provides specific data capture and processing functions for use with the
Richter System, as well as the normal full suite of processing and visualisation functions used for acoustic
emission and ultrasonic surveying technologies (appropriate software permissions and keys are required).
These include:

Stream Visualiser – allows the entire data stream to be concatenated and visualised as either a
waveform summary or sonogram, with various processing functions available;

InSite Leach (Streamer Leach) – allows the entire data stream recorded using eXstream16 to be
harvested for discrete events using multi-channel software triggering algorithms;

InSite Leach (AutoLeach) – allows acoustic emissions and ultrasonic surveys acquired using
eXstream16 in master-slave triggering mode on the set of mini systems to be automatically captured
and managed within InSite’s normal data structures (with real-time processing option).
1.2
Specifications
The Richter unit is typically used in a stand-alone mode or as part of a master-slave system, where the
amplified sensor output is fed directly to the DAQ IO channels (not triggered) and streamed to disk. The
Richter unit (or Richter system) may alternatively be used in trigger mode i.e. AE event monitoring, in
conjunction with the THC. Therefore the Richter system may consist of the following hardware units:
1) Richter16 Data-Acquisition System (DAQ);
2) Pulser-Amplifier System (PAS);
3) Trigger and Hit Count Unit (THC).
The specifications for all three instruments are presented in this section.
