smu.digitize.rel.acquire()

This function acquires a measurement and stores it as the relative offset value.

Type TSP-Link accessible

Affected by Where saved Default value

Function

Yes

Usage

smu.digitize.rel.acquire()

Details

This command triggers the instrument to make a new measurement for the selected function. This

measurement is then stored as the new relative offset level.

When you send this command, the instrument does not apply any math, limit test, or filter settings to

the measurement, even if they are set. It is a measurement that is made as if these settings are

disabled.

If an error event occurs during the measurement, nil is returned and the relative offset level remains

at the last valid setting.

You must change to the function for which you want to acquire a value before sending this command.

The instrument must have relative offset enabled to use the acquired relative offset value.

After executing this command, you can use the smu.digitize.rel.level attribute to see the last

relative level value that was acquired or that was set.

Example

smu.digitize.func =

smu.FUNC_DIGITIZE_CURRENT

rel_value = smu.digitize.rel.acquire()

smu.digitize.rel.enable = smu.ON

print(rel_value)

Acquires a relative offset level value for the

digitize current function and turns the relative

offset feature on.

Output the value of the offset.
