Comments Changing Ranges: The present range setting will determine the maximum and minimum values that can be entered without error. Changing range will keep the level at the same percentage of the new range. For example, if level is set to 2.0 on the 4 V range, the level is set to 8.0 if you change to the 16 V range (50% of full range). Setting Levels: Changing ranges will change an existing level to the same percent of full scale on the new range. For example, if an 8.0 level is set on the 16 V range and the range is then changed to the 4 V range, the level attempts to change to 2.0 V (still 50%). However, for this range, this action causes an error message to be generated and the new level is set to the maximum or minimum the new range will support. Trigger Slopes: TRIG:SLOPe specifies the direction of signal movement through which the level will trigger the digitizer. TRIG:SLOPe POSitive causes a trigger when the signal passes through the level and rises above the specified level. TRIG:SLOPe NEGative causes a trigger when the signal passes through the level and falls below the specified level. Executable when initiated: NO Coupled command: YES. Range setting Reset (*RST) condition: 0.00 on all channels TRIGger:LEVel? TRIGger:LEVel<channel>? queries the value of the trigger level set on the specified channel. TRIGger:MODE TRIGger:MODE NORMal | MASTer<n> | SLAVe<n> sets the trigger mode. Master and Slave parameters set the modules for use in connecting more than one module together for simultaneous measurements from the same trigger and sample. Parameters Comments Chapter 3 Name Type Range of Values Default Value <n> numeric 0, 2, 4, 6 none Master and Slave Operation: NORMal sets standard trigger operation and the specified trigger and sample sources are used. MASTer<n> and SLAVe<n> pairs a sample line and a trigger line which are then used for multiple unit synchronization. See Chapter 2 for more information, including diagrams.
