Introduction to Main Functions

GO/NO-GO Determination

User’s manual section 10.9, “Performing GO/NO-GO Determination Using Zones”

User’s manual section 10.10, “Performing GO/NO-GO Determination Using

Measured Waveform Parameters”

This function determines whether a waveform enters or does not enter a specified range, and then performs (GO) or

does not perform (NO-GO) a certain action.  Determinations are made by specifying a zone on the on-screen

waveform, or specifying a waveform parameter range.  The GO/NO-GO actions include sounding a buzzer, saving

data, printing a screen image, and sending an e-mail message (with the /C10 option installed).

Snapshot

User’s manual section 8.6, “Taking Snapshots and Clearing Traces”

When not in Single or Single(N) mode, the displayed waveform is periodically updated or displayed in roll mode.

Using the Snapshot function, you can temporarily freeze a waveform on the screen that would ordinarily be lost when

the screen is updated.  Snapshot waveforms are displayed in white, allowing you to easily compare them with the

updated waveforms.  Furthermore, you can save snapshot waveforms to a memory medium, or print them out as

screen images.

Ethernet Communications

User’s manual chapter 13, “Ethernet Communications (Optional)”

You can transmit data or control the DL7400 using the Ethernet (available with the /C10 option).

Saving and loading data to and from a network drive

You can save or load data and screen images to and from an FTP server* on a network in the 
same way that you can do so using the internal storage medium, external SCSI device, or USB 
storage device.

* A PC or workstation running the FTP server function

Printing to a network printer

Screen images can be printed to a network printer in the same manner as they are printed to 
the built-in printer (optional) or USB printer.

Sending mail

You can have the DL7400 send a mail at regular intervals containing its current settings and 
measured values.  You can also have mail sent based on a GO/NO-GO determination or 
upon activation of an acquisition trigger that contains the trigger time and other information.

Accessing the DL7400 from a PC or workstation

You can access the DL7400 from any FTP client* on the network, and obtain files from the 
DL7400 internal storage medium, external SCSI device, or USB storage device.

* A PC or workstation running the FTP client function

Web server

You can set up the DL7400 as a Web server.  From the DL7400 Web page, you can transmit 
files, monitor the displayed waveform, perform basic setting operations on the DL7400, and 
obtain waveform data.
