Section 11: TSP command reference Model 2601B-PULSE System SourceMeter Instrument Reference Manual
11-178 2601B-PULSE-901-01A April 2020
The min and max entries each have the attributes defined in the following table.
String indicating the function that was measured for the reading (current,
voltage, ohms, or watts)
The full-scale range value for the measurement range used when the
measurement was made
String indicating the source function at the time of the measurement
(current or voltage)
String indicating the state of the source (off or on)
Full-scale range value for the source range used when the measurement
was made
If bufferVar.collectsourcevalues is enabled, the sourced value in
effect at the time of the reading
Status value for the reading; the status value is a floating-point number that
encodes the status value into a floating-point value
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
