Data acquisition unit to measure the selected signal on demand.

Main Features:

Modules allow wide range of measurements and are suitable for a variety of measurements due to flexible combinations.

Measurements for different applications can be added to the module.

• • Voltage module (GL7-V)
  • Voltage/Temp. module (GL7-M)
  • High-speed voltage module (GL7-HSV)
  • High voltage module (GL7-HV)
  • Bridge module (GL7-DCB)
  • Charge module (GL7-CHA)
  • Voltage output module (GL7-DCO)
  • Logic/Pulse module (GL7-L/P)

Measurements for different applications can be added to the module

• Each of the 10 units can include a different input/output module ^(*1)
• Up to 10 input/output modules of the same kind can be attached to one main unit^(*1)

^{(*1)* If different types of modules are attached, the effective sampling speed of the system is to up to the fastest sampling speed among the installed modules. When the maximum sampling speed of the module is slower than the maximum sampling speed of the fastest amplifier, signal will be sampled with maximum sampling speed of the module. The same data is saved with the system sampling speed until new data is captured on the slower units.* The number of modules that can be attached is limited by the type of module. Up to 10 modules (maximum 112ch with 7 GL7-L/P module, max 100ch with GL7-V or GL7-M module).
For Logic/Pulse module (GL7-L/P):
　Maximum 7 units allowed using logic option (112ch).
　Maximum 2 units allowed using pulse option (32ch).
　(The mode for logic or pulse can be set for each unit.)
For Strain module (GL7-DCB):
　Maximum 8 units allowed with additional two other amplifier units. (Number of channels is limited to 112ch.)* For the logic/pulse module, the number of channels can be limited by the selected sampling speed when the module is attached together with other amplifier modules.
　1μs sampling interval: up to 8 channels
　2μs sampling interval: up to 16 channels (If two modules are attached, channel #1 to #8 in each unit can be used.)
When pulse mode is used, the maximum sampling speed is the 100μs. The data will be updated every 100μs.}

Maintains the maximum sampling speed even when the number of input/output modules are increased

Maintains the maximum sampling speed even when the number of input modules for voltage or voltage/temperature are increased.

Up to 1120 channels can be measuring using the PC platform

Up to 10 units of the GL7000 can be connected to 1PC through LAN or USB and controlled using the software.

Up to 5 units of the GL7000 can be fully synchronized using the sync. cable

The start/stop, trigger and sampling can be synchronized in the GL7000 when they are connected by a sync. cable. The master and slave units are automatically identified.

High-definition display module with touch panel enables measurement in various configuration

• The detachable display module allows both stand-alone and embedded system configurations
  >Measurement settings and signal measurement can both be done without a PC by attaching the display module. The display module can be moved to different locations for remote operation by connecting it to the main module with a LAN cable*, it also can be embedded into the system. The module can stile be operated by the PC even when the display module is connected

Large easy-to-read 5.7-inch (VGA 640 x 480) high-definition LCD monitor

Utilizes a bright clear TFT color LCD monitor. Makes it easy to read data in waveform or digital form and to check measurement parameter settings.

• • Y-T display
  • Digital display
  • XY display
  • FFT display

The display unit incorporates a touch panel system to provide convenient on-site operation

• Function Menu
  >Easy access to each functions from listed icons.
• Touch the icon, move to the next setting menu screen.
• The display waveform is able to expand or shrink.

Supports multiple destinations to save the captured data according to the conditions of the measurement

Supports multiple types of storage

(*1)

Capacity of memory device may be smaller than above depending on time of production.

(*2)

The file for recording data is limited up to 4GB on firmware version 2.0 or later, 2GB on firmware version 1.6 or before.
There is function that saving data to multiple files without losing data until capturing data is stopped.

(*3)

The hot-swap is possible when the sampling is slower than 100ms.

(*4)

Number of modules are limited. The storage capacity might differ by its production date.

Useful functions for reacording and replaying data

• Dual-Sampling Feature *
  >Dual sampling speed can now be configured at the same time. While recording long intervals on the slow sampling speed, trigger set can start recording dynamic transient signals at a fast sampling speed.
  * It is required firmware version 2.0 or later.
• Enhanced relay recording function *
  >Up to 4GB data files can be recorded on a relay mode where no data loss occurs in between the files. This offers long term recording of dynamic data recording. Relay mode captures all data in between the data files eliminating data loss.
  * The file for recording data is limited up to 4GB on firmware version 2.0 or later, 2GB on firmware version 1.6 or before.
• Ring mode
  >Saves most recent data of specified number after recording stops.
• Back up recording data
  >The data file can be created periodically for purpose of backing up data while recording it, and the file is automatically transferred to another storage device on the unit or FTP server on the network. Backup interval: 1, 2, 6, 12, 24 hour(s)
  Backup file destination: SD memory card, SSD module (optional), FTP server
  Data file format: GBD (binary) or CSV (text)
  * The CSV format is available with firmware version 2.10 or rater.
  −Available sampling speed is the 10 ms or slower when using the CSV format.
  −When the RING mode or external pulse synchronization sampling is selected for recording, the backup function is not available.
  −The storage device specified as the recording destination of the measurement data can not be set as the transfer destination of the backup file.
  −When backup is enabled and data file format is specified with CSV format, SD memory card exchange (hot-swapping) and RELAY recording are not available.

Other functions *

* It is required firmware version 2.0 or later.

Support interface frendly with the PC

• Supports Ethernet and USB2.0
  >Ethernet (10BASE-T, 100BASE-TX) and USB2.0 (hi-speed) interface are standard.
  Each interface port is located in the front of the unit for easy cable connection.
  It supports the following functions:

SDK (Software Development Kit) is offered for free

Software Development Kit (SDK) is available for real time data transfer and beyond for custom application developed for your need.

• USB driver
• Manual (Main unit controls, data communication, data file, etc.)
• Sample program (in Visual C++, Visual Basic, .NET framework)
• Key commands have been set as modules for simpler implementation with LabVIEW.  Higher module has added 
  (Connection, Waveform Display, Digital Indicator, CSV conversion, file acquisition)

* Module type library for LabVIEW will be available in December.
