Example
reset()
testData = dmm.makebuffer(1000)
testData.collecttimestamps = 1
dmm.nplc = 0.5
dmm.range = 0
dmm.configure.set("Dcv_100mV")
dmm.setconfig("slot2", "Dcv_100mV")
scan.create("2035:2040")
scan.execute(testData)
print(testData.times[1])
printbuffer(1, 6, testData.times)
This example creates a reading buffer
named testData, configures the buffer to
collect time and date data, sets and saves
the DMM configuration, creates a scan list,
and then runs the scan.
The print() command then outputs the
time of the first reading in the reading buffer.
Output:
09:14:48
The printbuffer() command then
outputs the time of readings 1 to 6 in the
reading buffer.
Output:
09:14:48, 09:14:48, 09:14:48,
09:14:48, 09:14:48, 09:14:48

Details
Reading this attribute returns the timestamp resolution value.
The finest timestamp resolution is 0.000001 seconds (1 μs). At this resolution, the reading buffer can
store unique timestamps for up to 71 minutes. This value can be increased for very long tests.
The value specified when setting this attribute will be rounded to an even power of 2 μs.
Example
buffer1.timestampresolution = 0.000008
Sets the timestamp resolution of
reading buffer 1 to 8 μs.
