1. Overview

1-1. Introduction

The SIR-3000 series is a lineup of data recorders consisting of a recording unit and measuring unit. The recording unit and measuring unit are used in combination together.

Seven speeds are available for both recording and playback so that high-speed data recorded at 4xspeed can be played back at 1/16xspeed, or the maximum 250 hours of data recorded at 1/16xspeed can be played in four hours at 4xspeed.

SIR-3400H (recording unit)

This device records data obtained from the measuring unit.

Two hard disk drives (HDD) are used for the recording media. Data is written simultaneously to the two HDDs so that even if a failure were to occur in one HDD, recording is still maintained in the other HDD. When the SMH-200 is used, the capacity of HDD is 200 Gbytes. The unit can continuously record the digital data of 128 ch x20 kHz (SIR-3032i / SIR-3032W) / 32 ch x80 kHz (SIR-3032W) for about 4 hours.

SIR-3032i/SIR-3032W (measuring unit)

This device sends the measured data to the recording unit.

Up to four measuring units can be connected to a single recording unit.

1-2. Major Features

Wideband, Multi-Channel

By combining with a measuring unit, the SIR-3000 series can be used to build the optimum system for measurement subjects.

Support for 32 ch x20 kHz is provided by combining the minimum configuration of the SIR-3400H and SIR-3032i.

Replacing the measuring unit with the SIR-3032W enables wideband recording at 32 ch x80 kHz. Connection of four SIR-3032i/W to the recording unit enables recording and playback to one HDD group at 128 ch x20 kHz.

Equipped with Sensor Input

The SIR-3032i/W (measuring unit) can supply power to the sensor with built-in pre-amplifier (IEPE type). This enables the sensor to be connected directly to the data recorder, realizing enhanced portability and saving total costs. A choice between the IEPE input (IEPE or TEDS) and conventional DIRECT input is available for each channel.

Input Range

The input range now covers ± 0.1 Vpk to ± 10 Vpk (Maximum 7 ranges), enabling a broad range of signals to be recorded and played back at the optimum levels.

Subchannels

In addition to the above analog channels, the recorder is equipped with the subchannels listed below to allow various types of subdata to be recorded or played back together with the analog data.
