Buffervar.relativetimestamps - Keithley 2450 Reference Manual

Model 2450 Interactive SourceMeter® Instrument Reference Manual
Example 2
printbuffer(1, 3, tD.readings)
For the buffer created in Example 1, print the three readings in buffer.
Output:
-9.6420389034124e-12, -4.5509945811872e-10, -9.1078204006445e-12
Example 3
for x = 1, 3 do printbuffer(x, x, tD.readings, tD.sourcevalues, tD.relativetimestamps)
end
For the buffer created in Example 1, print the 3 readings, including the measurement, source value, and relative time
for each reading.
Output:
-9.6420389034124e-12, 2, 0
-4.5509945811872e-10, 2, 0.277194856
-9.1078204006445e-12, 2, 0.569614783

bufferVar.relativetimestamps

This attribute contains the timestamps, in seconds, when each reading occurred relative to the timestamp of
reading buffer entry number 1.
Type TSP-Link accessible
Attribute (R) Yes
Usage
relativetimestamp = bufferVar.relativetimestamp[N]
relativetimestamp
bufferVar
N
Details
This read-only attribute is an array (a Lua table) of timestamps when each reading occurred relative to the
timestamp of reading buffer entry number 1. These timestamps are equal to the time that has lapsed for each
reading since the first reading was stored in the buffer. Therefore, the relative timestamp for entry number 1 in
the buffer is 0.
