Recording/Playback
By adopting the 16 bit linear quantization, the dynamic range of 90 dB Typ is achieved. Further more the
phase difference between channels is suppressed to less than 1 degree. And the analog input level is allowed
to
±133 % of the input range value, and the input DC offset of each channel can be automatically or manually
adjusted within
±100 %.
Time Axis Conversion
Data speeds for recording and playback can be selected from the 7 levels of 4, 2, 1 (normal speed), 1/2, 1/4,
1/8 and 1/16. Data can be recorded for a maximum of 256 hours at 1/16 speed when using a 200 GB HDD.
By playing back at low speed the data recorded at high speed, data can be converted to the playback frequency
to meet the process speed of the external analyzing equipment.
Synchronized Operation
By connecting two recording units with the synchronizing cable (option), the synchronized recording/playback
can be performed with accuracy of a quartz level.
This enables doubling of the number of channels without reducing the frequency bandwidth or data transfer
rate.
Trigger Recording
Recording can be started by receiving the trigger signal from the external source.
Once the pre-trigger is enabled, a built-in large capacity data buffer memory allows data to be recorded
before and after a trigger. This is useful for recording suddenly-occurring phenomena such as lightning and
avalanches.
Compatibility with Computers
Data recorded in HDDs by the SIR-3000 series can be read out directly using the optional Media docking
station (STC-3010).
Therefore, even if the recording unit is not available, data can be directly analyzed.
High-speed Data Transfer Interface
By employing the high-speed data transfer interface (option), digital data can be transferred to a computer in
real-time during recording or playing back. (The transfer speed depends on the computer performance.)
Control Functions
The unit can be controlled from the local (front panel) or from the host computer via Ethernet.
