GL7-DCO   Analog Voltage Output Module

GL7-DCO Analog voltage output module simulates a recorded data form the GL7000 and outputs the source to the original equipment for mock simulation of anomalies and long term trend.  The output signal can be in a simple waveform sampled at its original recorded intervals and can output a sine, pulse, ramp, triangle wave forms, or DC signals.

Analog voltage output from saved data on the main GL7000 reproduces anomalies and trend data from the recorded files

By reproducing recorded data, you are able to simulate the symptoms in real time.

The reference signal can be created using the GL-Wave Editor (Excel macro) software, you are able to output an analog voltage signal from this module

Saved data can be edited using the GL-Wave Editor which then can be used as a output signal for simulating the analog voltage out.

The GSD is an abbreviation for Graphtec Binary Data that is specified by Graphtec

The Software of the GL-Connection and GL-Wave Editor are standard accessory software for the GL7000 data platform

Simultaneously capture and output analog voltage from the GL7-DCO while recording data on other modules

By simulating abnormal signal conditions for the output of the recorded data, you can record and simultaneously measure the impact of the simulated data on the equipment being simulated by measuring strain, vibration, temp, and other conditions of the target test object.
