Latency Calibration Commands

The Latency Calibration commands allow to calibrate the deterministic

latency in the data path between the digitizer and another module

connected via ODI links, for example a DSP or an AWG.

:CALibrate:SYNC:INPut:LEVel

Command

:CALibrate:SYNC:INPut:LEVel <level>

Description

This command sets the threshold level of the Sync In.

Query

:CALibrate:SYNC:INPut:LEVel?

Description

This query returns the current threshold level of the Sync In.

:CALibrate:LATency:LCMPeriod

Command

:CALibrate:LATency:LCMPeriod <lcm_period>

Description

This command sets the Least Common Multiple (LCM) period value to be

used for core clock phase alignment. This value determines the frequency

of the signal sent out at the SYNC OUT. The formula for the frequency is

f = 400MHz / LCM period. Only even values for the LCM period are

allowed.

Query

:CALibrate:LATency:LCMPeriod?

Description

This query returns the current LCM period.

:CALibrate:LATency:MODE

Command

:CALibrate:LATency:MODE {SEParate | COMBined}

Description

This command selects the latency calibration mode.
• SEParate – Phase alignment to the master’s core clock and latency

calibration are separate steps.

• COMBined - Phase alignment to the master’s core clock and latency

calibration are done in the same step.

Query

:CALibrate:LATency:MODE?

Description

This query returns the current latency calibration mode.
