For setting the trace buffer, see “Trace Buffer Setup dialog box” on page 4-34.
Inure 6.-5.1(-)-3.4(7)6.., the variables indicate the followin data.
• VOLT: Vltage measurement data
• CURR: Current measurement data
• RES: Resistance measurement data
• TIME: Time data (timestamp of the measurement start trigger)
• STAT: Status data or limit test status
• SOUR: Source output data
• CALC: Math (calculation) result data or limit test data (= raw data - offset data)
