Output data formats
Data format for system mode readings
For system mode operation, use the DO command to get one or more triggered readings. After
sending the DO command string and addressing the 4200A-SCS to talk, the output data string is sent
to the computer in the following format:
X±N.NNNNE±NN,X±N.NNNNE±NN,...X±N.NNNNE±NN
Data status
The hierarchy for data status is L, V, X, C, T, N, where X is:
• N: Normal
• L: Interval too short
• V: Overflow reading (A/D converter saturated)
• X: Oscillation
• C: This channel in compliance
• T: Other channel in compliance
