:CALibrate:LATency:MODE

:CALibrate:LATency[:STEP]

Keysight M8131A 16/32 GSa/s Digitizer User's Guide
f = 400MHz / LCM period.
<lcm_period> The LCM period as an even integer between 2 and 32768.
Query
:CALibrate:LATency:LCMPeriod?
Description This query returns the current LCM period.
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. This mode is used for latency setup
between M8131A and M8132A DSP.
• COMBined - Phase alignment to the master's core clock and latency
calibration are done in the same step. This mode is used for latency
setup between M8131A and M8121A AWG.
Query
:CALibrate:LATency:MODE?
Description This query returns the current latency calibration mode.
Command
:CALibrate:LATency[:STEP] {GSYNc | ALIGnphase | SSYNc
| ARMadjust | PREPare}
Description This command executes a step in the latency calibration of the data path
between master and slave. As mentioned in brackets, some commands are
sent to and affect only the master and some only the slave module. It is
indicated as well, when commands are relevant only for one calibration
mode (SEParate, COMBined).
• GSYNc - Generate clock signal at Sync Out (master, SEParate).
• ALIGnphase - Use the clock signal received at Sync In to align the
phase of the core clock (slave).
• SSYNc - Stop the clock signal generation at Sync Out (master).
• ARMadjust - Arm the module for latency adjustment (slave). When the
master starts sending data over the ODI, the latency is measured in the
slave and the FIFOs are adjusted accordingly.
• PREPare - Set the Sync Out to pulse mode (master, SEParate). When
data streaming is started, a single pulse is sent at the Sync Out.
