The SIR-1000 Series recorder can record video and measurement data

simultaneously on a single tape cartridge using optional video board,

SVB-10. The visual image played back on the video channel can be used

as complimentary analysis information in

analysing the measurement data.

Employing MPEG compression scheme

high quality picture can be recorded and

played back. Slow or fast replay is

possible by playing back at a different

tape speed from that of recording. Still

picture is also possible by pressing

PAUSE key. On input video format of

either NTSC or PAL can be selected

manually and video signal in the same

format as the input is played back.

Tape speed can be selected from a wide range of choices both on

recording and playback. During recording, for example, tape

speeds of 1

, 1/2

, 1/4

, 1/8

and 1/16

can be selected to

provide from 2 to 32 hours of recording time. Upon playback, long

recordings can be played back quickly（up to 16 times the

recording speed）to decrease data reproduction time or more

slowly than the recording speed（down to 1/16th the recording

speed）to expand the data time base. Output filters are provided

for the whole bandwidth at any tape speed to smooth out the

reproduction waveform.

Time axis conversion



The PCM system provides a dynamic range of 80 dB or more

(SIR-1000/-1000i）through 16-bit linear quantization and independent

AD/DA conversion for each channel. This not only allows extremely

accurate data recording but also facilitates the input range settings.

In addition, the adoption of 64 × oversampling digital filters provides

nearly linear phase characteristics and achieves an inter-channel

phase difference of less than 1 degree（SIR-1000/SIR-1000i）. The

analog input level has an allowable range of up to 133% of the full

scale range setting. （The analog characteristics specified in this

data sheet are for up to 133%.） And the input DC offset can also be

adjusted within the range of ±100%. The analog output level can be

selected from ±1 Vpk, ±2 Vpk or ±5 Vpk （calibrated output）, or

from ±0.5 to 5 Vpk （continuous variable output）.

High-grade recording and playback

The cartridges use the newly

developed AME（Advanced Metal

Evaporated）tape which features

superior output characteristics,

reliability and durability. The SIR-

1000 Series' real-time verify-rewrite

function reads the data written on

the tape during recording and

rewrites the data at once if errors

occur. This reduces data dropout to

virtually zero and greatly improves

data integrity. Furthermore, the SIR-1000 Series is equipped with an

active head cleaner that automatically detects and cleans the heads

to keep them constantly clean even when the SIR-1000 Series is used

outdoors.

The main unit has a built-in, large-capacity buffer memory

enabling pre-trigger data of 3 seconds（normal speed）to be

recorded on tape. This allows reliable recording of unpredictable

events and transient signals.

Pre-trigger recording

Care has been taken to ensure easy operation during multi-

channel, on-site measurement.

●

16-channel bar meter display : The incoming signal level for

16 channels is displayed on a backlit LCD panel with a wide

viewing angle for high visibility outdoors and in dark locations.

The display can be switched to match the measured phenomenon

such as decibel（dB）for noise and vibration and percentage（%）for

stress and distortion.

●

Test signals（internal or external） : Four types of test signals（±

100% AC sine wave, ＋100％ DC, −100% DC and 0V）are stored as

digital data and can be used as highly accurate reference signals

for the analog channels. Users can also input a reference signal

from an external source to channel 1 for distribution to all

channels as a reference signal.

●

Calibration : The analog channel DC offset and gain can be

calibrated.

●

Auto range/auto offset : The analog channel input range can

be set and the input offset canceled automatically.

●Setting for all channels : Parameters for all channels can be

set by pressing one key.

●

High-speed tape search : This function allows rapid access to

target data stored on the tape. Also, storing the Table of Contents

（ID and tape address information）in the Memory-In-Cartridge

allows even higher speed searches.

●

Self check : The self diagnostic check can be performed to

ensure the operations.

In addition to the key switches on its front panel, the SIR-1000 Series

can be controlled from the SRM-10 dedicated remote controller（

option）, RS-232C port, or relay contact port. The SRM-10 is a

highly functional remote controller with an LCD display panel

identical to that on the recorder main unit, including a 16-channel

bar meter display. The SRM-10 allows remote monitoring of the

recording setup information, tape address information and other

information. The RS-232C port is used when controlling the

recorder from a host computer, and the relay contact port is used

with TTL level external signals. Furthermore PCscan III software

with STB-30 can control via SCSI.

Versatile control functions



The SIR-1000 Series operates on AC 100/120 V （90 to 132 V, 47 to

440 Hz）, AC 220/240 V（198 to 250 V, 47 to 66 Hz）, or external DC

12 V（11 to 30 V）power source. Also large-capacity lithium ion

battery pack can be mounted on the data recorder for convenient

use outdoors. AC can be backed up by external DC or the battery

pack, and external DC can be backed up by the battery pack to

allow uninterrupted recording of valuable data.

The SIR-1000 Series has dimensions of 340 （W） × 115 （H） × 260 （D）

mm and weighs approximately 7.5kg（SIR-1000）, 7.6kg（SIR-1000i）,

7.7kg（SIR-1000W）（basic configuration）, giving it the best

portability and space factor of any data recorder in its class. In

addition, the SIR-1000 Series tough-durability is assured by the use of

strong cast aluminum in the unit

s casing and steel frame

construction for your difficult field environments.

applications such as telemetry and

monitoring digital network. The SBS-10A

or SBS-10S is mounted in one of the option slots on the rear panel

of the SIR-1000 Series. 

Digital data can be recorded either alone or together with analog

data. In addition to the functions the SBS-10A offers, the SBS-10S

can synchronize the recorder with external clock up to 24 MHz

and can record digital data at any desired bit rate by using

variable buffer memory. The number of high-speed digital channels

can be switch-selected to 1, 2, 4 or 8-channel mode.

High-speed digital data recording

Video recording

In addition to the analog data channels, the SIR-1000 Series main

unit is equipped with auxiliary channels as standard, allowing

other useful information and data to be recorded and played back

along with the main analog data.

●

AUX-1（serial digital channel） : tacho pulse, etc.

●

AUX-2（analog channel） : IRIG-B time code signals, etc.

IRIG-B time code calibrates the recorder

s internal clock.



●

Voice channel : voice annotations

Convenient auxiliary channels

The number of channels for the SIR-1000/SIR-1000i can be

expanded up to 128 （16 channels for SIR-1000W）and 2 hour

recording is possible regardless of the channel configuration.

Synchronous recording and play back up to 8 units are also

possible using an optional SSB-10, Multisync adapter.

●SIR-1000/SIR-1000i ：The SIR-1000/SIR1000i in basic configuration

features a 20kHz bandwidth for all 16 channels. In addition, 32

channels of DC to 20kHz analog data can be simultaneously

recorded on a single data cartridge by combining the recorder

with an optional SCX-32/SCX-32i Channel Expansion Unit. The

number of channels can be further increased by adding channel

expansion units. 128 channels of 5kHz analog data can be recorded

with a system consisting of the SIR-1000/SIR-1000i and seven 

SCX-32/SCX-32i

●SIR-1000W :The SIR-1000W is capable of recording 4 channels

of DC to 160kHz or 8 channels of 80kHz analog data. With an

optional SCX-16W Channel Expansion Unit the number of

channels is expanded to 16 for the bandwidth of 40kHz. 
