Modern conveniences such as Ethernet and USB 2.0 interfaces are included, along with a PCMCIA flash memory card port, so you can easily get the data out of your GL500A and transfer it to your computer.  Data are normally captured into the GL's large internal memory, at rates selectable from 1 ms to 1/hour!  You can record for hours, days, or even weeks with the 2 MS memory.

We've got input modules available with and without isolation (with twice as many channels) depending on your requirements.

Dynamic channels demand filtering, we we've got it.  Select from off, line (1.5 Hz), 5 50, 500 Hz (-3dB roll-off, -6 db/Q).

While you're trending data at low-speed to one file, triggered data can be captured at a higher speed to a separate file!  Sample rates as high as 500 kHz can be achieved when capturing one channel, or as fast as 20 kHz when all 16 channels are captured.

Remote control functions such as pen heat on/off, chart feed start/stop, synchronization with an external pulse, output of paper-end signal, input of event marker signals, and input/output of time marker signals enable automated, unmanned operation.

Rear panel reference voltage output connectors enable easy calibration whenever plug-in units have been exchanged.  The reference voltage output used for calibration is 1 V d.c.
