GP200 Warping in the Brooks Expert Support Tool

For GP200 devices, an adjustment called “Warping” allows a 

user to adjust the device’s response to match their standard, 

such as within a certain environment. The user enters 

performance data of their device as measured in their 

environment, then the software uses a curve fit to adjust the 

device’s response accordingly. Warping requires a Brooks 

Expert Support Tool license. For GP200 devices, a warp 

adjustment is added to the device’s factory calibration and 

can be cleared from a flow page without affecting the factory 

calibration. The same flow page may then be used again 

without the warp adjustment.
