SRS Residual Gas Analyzer

The VI takes a few moments before the scan begins in order to perform some initialization tasks on the

RGA. After this time, you should see traces corresponding to the partial pressures detected by the RGA

as its mass filter is swept. If the traces do not appear after thirty seconds or you get an error, use the RGA

COM program supplied with your RGA to verify communications are set up correctly. Make sure the

power to the RGA is on (check the power LED), verify the COM port setting is correct, and test the

cabling.

Concepts from the example:

Within LabVIEW, view the block diagram of SRSRGAa Simple Table (press Control-E if you are already

looking at the front panel of the VI). The figure below shows this block diagram.
