## Command Syntax

    :MEASure:DATA:UINTerval:DWMode {AUTomatic | SAUTomatic}

## Query Syntax

    :MEASure:DATA:UINTerval:DWMode?

## Description

For the Unit Interval measurement, specifies whether Automatic clock recovery or Semi Automatic clock recovery be performed.

- In Automatic mode, the data rate is found by searching your waveform for the narrowest data pulse. When the Automatic mode has trouble finding the data rate due to excessive high-frequency jitter on the waveform, the Semi Automatic mode can be used.
- In the Semi Automatic mode, Infiniium starts by searching around the data rate that you specify then automatically finds the data rate.
