TraNET FE User Guide
2.3 Basic Mode of Operation
TraNET FE devices are based on an embedded microcomputer with a hard disk, a Gigabit Eth-
ernet controller and a PCIe bus interface to control the installed TPCE-Modules. The firmware
runs under a Linux operating system.
TraNET FE operates via Ethernet Link as a TCPI/IP Server. A simple point to point connection to a
client PC (e.g. Notebook PC) allows an easy installation. Otherwise it can be connected to any
existing LAN and allows remote operation. For establish a WIFI connection, an additional WIFI
router must be used.
There are four different operation modes in which the data acquisition instrument can be used.
Any of these operation modes are ready to use in all driver interfaces or in the Application soft-
ware.
2.3.1 Scope
In Scope mode the device runs like an Oscilloscope. Incoming data from the ADC are written
into the on-board memory until a trigger condition occurs. After the trigger condition, the
measurement continuous until the post-trigger time is over and stops. The length of the mea-
surement is limited by the maximum memory available on the board.
2.3.2 Multi-Block
Multi-Block Mode works like the Scope mode but with the addition that the available on-board
memory is splitted up in several blocks. On each trigger, a new part of the memory is used. This
way, the on-board memory can be used more effective than in the Scope mode. The maximum
number of blocks is limited by the block size and the available memory.
2.3.3 Continuous
In the Continuous mode incoming data from the ADC‘s are buffered on the on-board memory
an then transfered immediately to the built-in hard disk of the device. The maximum recording
length is only limited by the hard disk size. The amount of data produced per second depend on
the used sampling rate and the number of activated channels. If the data rate is higher than the
PCIe interface or the hard-disk write throughput, some data from the on-board buffer get lost.
