In this Appendix:

The three measure readings, timestamps, and source values will be stored in the
buffer.

Step 3: Read the buffer

The following code will output the three sets of data (nine values) in the same
message:

rb1 = smua.nvbuffer1

printbuffer(1, rb1.n, rb1, rb1.timestamps, rb1.sourcevalues)

For the above

printbuffer

function,

is the starting index for values to output;

rb1.n

is the ending index (

= the number of readings in the buffer, which in this

case is 3);

rb1

includes the measured readings;

rb1.timestamps

includes the

timestamps; and

rb1.sourcevalues

includes the source values.

Example output:

1.234567e-03, 5.555555e-02, 1.00, 2.362360e-03,

8.888888e-02, 1.00, 2.362368e-03, 1.111111e-01,

1.00

The above output is returned in the following order:
reading1, timestamp1, sourcevalue1, reading2, timestamp2, sourcevalue2,
reading3, timestamp3, sourcevalue3
Refer to Step 3 of “

Running a factory script

” in

Section 3

for more examples on

reading the buffer.
