smuX.measure.overlappedY()

This function starts an asynchronous (background) measurement.

Type

TSP-Link accessible

Affected by

Where saved

Default value

Function

No

Usage

smu

X

.measure.overlapped

Y

(

rbuffer

)

smu

X

.measure.overlappediv(

ibuffer

,

vbuffer

)

X

Source-measure unit (SMU) channel (for example,

smua.measure.overlappedv()

applies to SMU channel A)

Y

SMU measurement type (

v

= voltage,

i

= current,

r

= resistance,

p

= power)

rbuffer

A reading buffer object where the readings will be stored

ibuffer

A reading buffer object where current readings will be stored

vbuffer

A reading buffer object where voltage readings will be stored

Details

This function starts a measurement and returns immediately. The measurements, as they are performed, are
stored in a reading buffer (along with any other information that is being acquired). If the instrument is configured
to return multiple readings where one is requested, the readings are available as they are made. Measurements
are in the following units of measure:

v

= volts,

i

= amperes,

r

= ohms,

p

= watts.

The second form of this function,

smu

X

.measure.overlappediv()

, stores current readings in

ibuffer

and

voltage readings in

vbuffer

.

This function is an overlapped command. Script execution continues while the measurements are made in the
background. Attempts to access result values that have not yet been generated cause the script to block and
wait for the data to become available. The

waitcomplete()

function can also be used to wait for the

measurements to complete before continuing.
If a given reading buffer contains any data, it is cleared before taking any measurements, unless the reading
buffer has been configured to append data.

Example

smua.measure.overlappedv(smua.nvbuffer1)

Starts background voltage
measurements for SMU channel A.
