Buffer reading attributes
Attributes that control which elements are recalled from the buffer are listed in
Table 7-6. To access specific elements, simply append the desired attribute to the
buffer designation.
For example, the following would return 100 Channel A readings from buffer 1:
printbuffer(1, 100, smua.nvbuffer1.readings)
Similarly, the following would return 100 Channel A source values from buffer 1:
printbuffer(1, 100, smua.nvbuffer1.sourcevalues)
Note that readings is the default reading attribute and can be omitted. Thus, the
following would also returns 100 Channel A readings from buffer 1:
printbuffer(1, 100, smua.nvbuffer1)
