SRS Residual Gas Analyzer

Simple Histogram

Try the example:

Open LabVIEW

Select the RGA LabVIEW Library

Open the Simple Histogram example, SRSRGAa Simple Histogram

From the front panel of the VI, set the COM port that the RGA is using

Set the noise floor, mass, and electron multiplier state

Run the VI

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 histogram bars corresponding to the partial pressures detected by

the RGA as its mass filter is swept. If the trace does 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.
