It can measure the desired signal according to the needs and can expand into other applications adding different amplifier modules.
Measurements for different applications can be added to the amplifier module. It is also possible to mix measurements by adding different types of modules.
The Voltage module, Voltage/Temperature module, High Speed Voltage module and Logic/Pulse models are available. The other modules will be released sequentially starting in the autumn of 2012.
Up to 10 amplifier modules can be attached for multi-channel measurements, with up to 112 channels on one GL7000.
Voltage* and Volt/Temp amplifier can maintain high-speed and multi-channel measurements without dropping the sampling speed, even if the number of modules are increased.
* In the High-speed voltage and Logic/Pulse module, the sampling speed will be limited by the recording medium.

Supports four destinations to save the captured data according to the conditions of the measurement
The RAM to save 2 million samples is built into each amplifier module. The data capture duration does not decrease with increasing numbers of channels because the built-in RAM for each amplifier module is used.
The 2GB of Flash memory is built into the main module. The captured data can be saved directly to the built-in Flash memory when the sampling is not faster than 1ms (sampling speed: 1 k Samples/s). Saved data is retained even when power is turned off because flash memory is used.
SD card slot (supports SDHC, up to 32GB) is standard on the main module. The captured data can be saved directly to the SD memory card when the sampling is not faster than 1ms (sampling speed: 1 k Samples/s). It supports hot-swap, so the SD memory card can be replaced during measurement without data loss.* The captured data can be transferred easily to the PC in offline condition.
* The hot-swap is possible when the sampling is slower than 100ms.
Allows large amounts of data to be quickly saved when the optional SSD module is attached. The captured data can be saved directly to the SSD when the sampling is not faster than 1µs (sampling speed: 1 M Samples/s).* It has a high vibration resistance and saved data is also retained even when power is turned off.
* The number of modules are limited.
Captured data is periodically transferred to the FTP server for backup when the GL7000 is connected to the LAN (Local Area Network).

The touch panel makes setting the conditions intuitive, and it can also be operated using the cursor keys similar to the GL series.
Utilises a bright clear 5.7 inch wide TFT color LCD monitor (VGA: 640 x 480 dots). Makes it easy to read data in wave form or digital form and to check measurement parameter settings.
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 still be operated by the PC even when the display module is connected.
* Up to 10m using CAT5 LAN cable (straight connection)
The GL7000 can be controlled by the GL-Connection software that is included. The software has convenient functions such as saving data to the PC, replaying captured data, and converting data form. It is an integrated application software for the GL series, the GL900, GL820 and GL220 can also be connected.*
* The version for supporting other GL series will be available in December 2012.
The measurement signal can be displayed as various types of screens by the unit, the module or the specific channels that are specified in the group function. It can also be displayed as a combination of the capturing data and captured data, the Y-T format and the X-Y format, simultaneously. Up to 112 channels can be displayed in each window.*
* In case of using dual screen, total 244 channels can be displayed.
For real time and the post processing.
