Specifications

The ability to press a button and store a captured waveform or screen image is valuable for

documenting investigative and development work. With an analog scope, the user needs to stop and

set things up to take a photograph. Contrast this to the digital scope, which just needs a button press

and typically less than 2 seconds to capture a screen image. This makes it more likely the user won't be

distracted from their work task.

Network operation

This describes the networking feature for the B&K Precision 254xB oscilloscopes. Other scopes will

likely have similar features but differ in operational details.

To connect to the scope over the network, you need to configure the IO settings. This is most easily

done if you have a DHCP (Dynamic Host Configuration Protocol) server available. This is often

provided with network devices such as cable routers, routers and switches, and company LANs (and

private networks can have a workstation set up to perform this task). The scope is told to use DHCP

and contacts the server to get an IP address for the scope. In the 254xB scope, you just press the OK

button in the configuration menu and, after a few seconds, the scope's display shows it has received an

IP address.

You can also configure the LAN settings manually. You'll have to supply an IP address, subnet mask,

gateway address, and DNS (domain name server).

Then all that's needed is to connect a web browser to the scope's IP address. If the scope had the IP

address of 192.168.1.13, you'd type http://192.168.1.13 into your browser and you should be able to

connect to your scope. Note: Some browsers such as Firefox may not work. If you're unable to connect,

try a recent version of Microsoft's Internet Explorer.

Once the browser is connected to the scope, you can view the scope's screen and a simulated control

panel:

The scope's display shows a red Rmt in the upper left corner to alert you that a connection has been

made to the scope.
