Agilent Technologies U2781A manual Simultaneous Synchronization SSI

3 Features and Functions

4During this identification operation, the trigger bus is used. Hence, any triggering activities on the backplane would be blocked.

5Prior to any triggering activities, you must stop the configuration activity by sending the following command:

SYSTem:IDentity {0OFF}

• Do not execute the above mentioned steps when the USB modules are in the

N O T E

process of acquiring data.

•You do not need to perform the above pre-configuration if you are using the Agilent Measurement Manager software. You are only required to press the “Refresh” button.

Simultaneous Synchronization (SSI)

Simultaneous Synchronization (SSI) provides synchronization between the USB modules. Figure 3- 7 illustrates an example of SSI.

SSI allows you to set one of the modules as MASTER and others as SLAVE. MASTER module sends the SSI signal to the slave modules via the backplane trigger bus. SLAVE modules will then receive the signal and begin synchronization with MASTER module.

The SCPI command below is used to set the module as master:

CONF:SSI MAST

Send the SCPI command below to set the module as SLAVE:

CONF:SSI SLAV
