Card Control Center

Software

Hardware information

Through the Control Center you can easily get the main information

about all the installed Spectrum hardware. For each installed card

there is a separate tree of information available. The picture shows the

information for one installed card by example. This given information

contains:

• Basic information as the type of card, the production date and its

serial number, as well as the installed memory, the hardware revi

sion of the base card, the number of available channels and

installed acquisition modules.

• Information about the maximum sampling clock and the available

quartz clock sources.

• The installed features/options in a sub-tree. The shown card is

equipped for example with the option Multiple Recording, Gated

Sampling, Timestamp and ABA-mode.

• Detailed Information concerning the installed acquisition modules.

In case of the shown analog acquisition card the information con

sists of the module’s hardware revision, of the converter resolution

and the last calibration date as well as detailed information on the

available analog input ranges, offset compensation capabilities

and additional features of the inputs.

Firmware information

Another sub-tree is informing about the cards firmware ver

sion. As all Spectrum cards consist of several programmable

components, there is one firmware version per component.

Nearly all of the components firmware can be updated by

software. The only exception is the configuration device,

which only can receive a factory update.

The procedure on how to update the firmware of your Spec

trum card with the help of the card control center is described

in a dedicated section later on.

The procedure on how to update the firmware of your

digitizerNETBOX/generatorNETBOX/hybridNETBOX with

the help of the integrated Webserver is described in a dedi

cated chapter later on.
