Attribute Description
bufferVar .dates
The dates of readings stored in the reading buffer; see
bufferVar.dates (on page 8-25)
bufferVar .extravalues The additional values (such as the sense voltage from a DC voltage
ratio measurement); the reading buffer style must be set to full to
use this option; see
bufferVar.extravalues (on page 8-27)
bufferVar .formattedreadings The stored readings formatted as they appear on the front-panel
display; see
bufferVar.formattedreadings (on page 8-29)
bufferVar .fractionalseconds The fractional portion of the timestamp (in seconds) of when each
reading occurred; see
bufferVar.fractionalseconds (on page 8-30)
bufferVar .readings The readings stored in a specified reading buffer; see
bufferVar.readings (on page 8-33)
bufferVar .relativetimestamps The timestamps, in seconds, when each reading occurred relative
to the timestamp of reading buffer entry number 1; see
bufferVar.relativetimestamps (on page 8-34)
bufferVar .seconds The nonfractional seconds portion of the timestamp when the
reading was stored in UTC format; see
bufferVar.seconds (on page
8-35)
bufferVar .statuses The status values of readings in the reading buffer; see
bufferVar.statuses (on page 8-37)
bufferVar .times The time when the instrument made the readings; see
bufferVar.times (on page 8-38)
bufferVar .timestamps The timestamps of readings stored in the reading buffer; see
bufferVar.timestamps (on page 8-39)
bufferVar .units The unit of measure that is stored with readings in the reading
buffer; see
bufferVar.units (on page 8-41)
Example 1
reset()
dmm.measure.func = dmm.FUNC_DC_CURRENT
testData = buffer.make(200)
format.data = format.ASCII
format.asciiprecision = 6
trigger.model.load("SimpleLoop", 6, 0, testData)
trigger.model.initiate()
waitcomplete()
printbuffer(1, testData.n, testData.readings, testData.units,
testData.relativetimestamps)
Reset the instrument.
Set the measure function to DC current.
Set the data format and ASCII precision.
Use trigger model SimpleLoop to create a 6 count loop with no delays that stores data in the reading buffer
testBuffer
.
Start the trigger model, wait for the commands to complete, and output the readings.
Use of
testData.n
(
bufferVar .n
) indicates that the instrument should output all readings in the reading
buffer. In this example,
testBuffer.n
equals 6.
Example of output data:
1.10458e-11, Amp DC, 0.00, 1.19908e-11, Amp DC, 1.01858e-01, 1.19908e-11, Amp DC,
2.03718e-01, 1.20325e-11, Amp DC, 3.05581e-01, 1.20603e-11, Amp DC, 4.07440e-01, 1.20325e-
11, Amp DC, 5.09299e-01
