Function name Description
start(...) This function starts a BGAN transmission (‘BPLT waveform’ mode).
Parameters:
<freq> Frequency in Hz [1518000000..1700000000], in steps of
1250 Hz
<bearer> Bearer type (e.g. R5T1X)
<coderate> Code rate [L14..L1,R,H1..H6]
<sid> Self Imposed Delay in s [0..80000]
<backoff> EIRP backoff in dB [0..10] with 0 as max, in steps of
0.01 dB
<pd> Payload data (ones | zeroes | random | counter | prbs)
<reps> Number of bursts to transmit (0 = continuous Tx)
<cw80> Use CW80 (Only certain bearers) (on | off)
<timeplan> Use Tx time-plan (on | off)
Constraints:
Expect a delay of approx. 80 to 160 ms from Tx start to the signal is
present on the RF connector.
stop() This function stops an ongoing BGAN transmission.
Constraints:
Expect a delay of approx. 160 ms from Tx stop to the signal is
removed from the RF connector.
configure_timeplan(...) This function configures a Tx time-plan.
Parameters:
<slot_index> Slot number [0..15]
<bearer> Bearer Type (R5T1X, R5T2X etc.) Empty string if slot is
unused
<coderate> Code rate (L14..L1,RE,H1..H6)
<freq_offset> Frequency offset in Hz [-100000..100000]
<backoff> EIRP backoff in dB [0;10] with 0 as max, in steps of
0.01 dB
<timing> Timing displacement of the burst in s [-180..180]

Note
The example file ex_tx_burst.py illustrates how a burst transmission is
generated using the functions described above. The example is on the
accompanying CDROM which is delivered with the Integrators development kit
which must be purchased separately (see details about ordering in section
3.10 on page 3-11).
