The min and max entries each have the attributes defined in the following table.
Attribute
Description
measurefunction
String indicating the function that was measured for the reading (current,
voltage, ohms, or watts)
measurerange
The full-scale range value for the measurement range used when the
measurement was made
reading
The reading value
sourcefunction
String indicating the source function at the time of the measurement
(current or voltage)
sourceoutputstate
String indicating the state of the source (off or on)
sourcerange
Full-scale range value for the source range used when the measurement
was made
sourcevalue
If bufferVar.collectsourcevalues is enabled, the sourced value in
effect at the time of the reading
status
Status value for the reading; the status value is a floating-point number that
encodes the status value into a floating-point value
timestamp
If bufferVar.collecttimestamps is enabled, the timestamp, in
seconds, between when the reading was acquired and when the first
reading in the buffer was acquired; adding this value to the base timestamp
will give the actual time the measurement was acquired
Example
reset()
smua.nvbuffer1.clear()
smua.measure.count = 10
smua.measure.v(smua.nvbuffer1)
stats = smua.buffer.getstats(smua.nvbuffer1)
print("n= "..stats.n)
print("mean= "..stats.mean)
print("stddev= "..stats.stddev)
print("min= "..stats.min.reading)
print("max= "..stats.max.reading)
Make measurements and store them in nvbuffer1. Print the statistics for the data.
Example output:
n= 10
mean= -2.3851394871599e-05
stddev= 4.406545187484e-07
min= -2.4557113647461e-05
max= -2.322196996829e-05
