====== Test Configurations ======

This section describes the sample configurations. Both soft- and hardware-setup
is described for each configuration. It is a good starting point for new users.

The following configurations are described here:

  * GPS for the reception and storage of a GPS-signal
  * Radio demonstrates a simple send/receive-setup
  * Radar is a simple game using radar-measurements of a moving ball
  * WLAN captures one or more 802.11-packets

===== Setup =====

This subsection contains some general overview of the different
hardware-subsystems.



==== RF-cards ====

Fig. <ref>fig:RF-cards</ref> shows the input/output connectors of the RF cards
(power supply omitted).

==== Rohde & Schwarz ====

All settings given in the figures start from a presetted state of the
signal-generator or -analyzer. You find a button labeled //Preset// that
sets the machine into a well-known state.

==== ICS-cards ====

In the following picture (TODO) you can see the ICS-cards on the back of the
computer. All the input and output-labels are visible.

==== FPGA ====

As described in section <ref>sec:FPGA</ref>, the FPGA can be programmed with two
versions of the code: one for the GPS-reception, and another one for everything
else. Please be sure to chose the appropriate code, or the given application
will not work.

Refer to section <ref>sec:FPGA</ref> on how to reprogram the PFGA.


==== Power supply ====

Wrong settings of the power-supply may destroy the attached hardware, so take
care and be sure to follow these instructions:

  - Switch up 1 & 2
  - Connect the power supply
  - Switch down 1
  - Adjust voltage and current using 3 & 4
  - Switch down 2
