Example
voltMeasBuffer = buffer.make(10000)
smu.measure.func = smu.FUNC_DC_VOLTAGE
print(smu.measure.read(voltMeasBuffer))
Create a buffer named
voltMeasBuffer
. Set
the instrument to measure voltage.
Make a measurement that is stored in the
voltMeasBuffer
and is also printed.

smu.measure.readwithtime()
This function initiates measurements and returns the last actual measurement and time information in UTC format
without using the trigger model.
Type TSP-Link accessible
Affected by Where saved Default value
Function Yes
Usage
reading, seconds, fractional = smu.measure.readwithtime()
smu.measure.readwithtime( bufferName )
reading
The last reading of the measurement process
seconds
Seconds in UTC format
fractional
Fractional seconds
bufferName
The name of the reading buffer, which may be a default buffer (
defbuffer1
or
defbuffer2
) or a user-defined buffer; if no buffer is specified, this parameter
defaults to
defbuffer1
Details
This command initiates measurements using the present function setting, stores the readings in a
reading buffer, and returns the last reading.
The
smu.measure.count
attribute determines how many measurements are performed.
When you use a reading buffer with a command or action that makes multiple readings, all readings
are available in the reading buffer. However, only the last reading is returned as a reading with the
command.
If you define a specific reading buffer, the reading buffer must exist before you make the
measurement.
