Chapter 3: Using the Logic Analyzer in Timing or State Mode

Setting Up Triggers and Running Measurements

Note that the e-mail is sent when the trigger occurs and not after the logic analyzer's acquisition memory is full.

You only need to specify one send e-mailaction per trigger sequence. As long as one trigger action sends e-mail, any trigger in the sequence will result in e-mail being sent. (You cannot specify different send e- mail setups in a trigger sequence.)

If the SMTP server has a problem with the default sender address

•You may need to specify a sender address that is recognizable by the server. A possible address might be the one specified in the To: field.

Message Format The automatically generated text is shown as follows:

Example: system14 : Slot C : Analyzer C has triggered

Where system14 is the analysis system IP address or alias you have assigned to it; Slot C is the frame slot the module is in; Analyzer C identifies the specific analyzer module from others when configured in a multi-module frame configuration.

Any text you add in the text entry area of the e-mail setup dialog will appear after the automatically generated text.

What is SMTP? SMTP (Simple Mail Transfer Protocol) is a TCP/IP protocol used in sending and receiving e-mail. A protocol is the special set of rules for communicating the end points in a telecommunication connection as they send signals back and forth.

Protocols exist at several levels in a telecommunication connection. There are hardware telephone protocols. There are protocols between the end points in communicating programs within the same computer or at different locations. Both end points must recognize and observe the protocol.

On the Internet, there are the following TCP/IP protocols:

•TCP (Transmission Control Protocol), which uses a set of rules to exchange messages with other Internet points at the information packet level.

•IP (Internet Protocol), which uses a set of rules to send and receive messages at the Internet address level.
