3.3 Test Mode Selection
After power-on, and optionally DUT configuration, the DUT is waiting for user input, in
detail a (Button) press event. As long as no (Button) press occurs, the system
remains in the state after power-on, see table below.
Each new (Button) press event switches to the next state, for example after the initial
state 0 (TRX_OFF) a (Button) press selects state 1, the radio transceiver starts to
transmit a continuous wave carrier at channel 11. The TX output power used is
according to the initial configuration.

Notes: (1) Note the individual LED order for each RCB type.
(2) B indicates LED is blinking, all other LED’s are off
(3) Due to the radio transceiver architecture the
unmodulated, CW TX RF frequency is at

channel
– 0.5 MHz. But still within the
modulation bandwidth of a modulated TX output
signal.
(4) These states using the PSDU data rate setting as
configured after power-on, refer to 3.2.
The selected channel is indicated by the corresponding LED, whereas the blinking
period indicates the operating mode.
A new (Button) press selects the next state. Once state 12 is reached, the next
(Button) press switches to state 0, and therefore sets the radio transceiver part back
into TRX_OFF (IDLE / Standby) state.
It is not possible to change the PSDU data rate within this operating mode. Doing this
requires a DUT power cycle as described in section 3.2.
