Burst

0/1

1

= RF on

 

 

 

0

= RF off

 

 

 

For non- bursted, non- TDMA systems, to have a continuous signal, set this bit to 1 for all

 

 

 

bytes. For framed data, set this bit to 1 for on timeslots and 0 for off timeslots.

To have the signal generator output a single pulse at the EVENT 1 connector, set this bit

 

Output

 

to 1. Use this output for functions such as a triggering external hardware to indicate when

 

 

 

the data pattern begins and restarts, or creating a data- synchronous pulse train by

 

 

 

toggling this bit in alternate bytes.

Pattern Reset

0/1

0

= continue to next sequential memory address.

 

 

 

1

= end of memory and restart memory playback.

 

 

 

This bit is set to 0 for all bytes except the last byte of PRAM. To restart the pattern, set

 

 

 

the last byte of PRAM to 1.

 

 

 

 

 

As seen in Table 8- 5, only four bits, shown in the following list, can change state:

bit 0—data

bit 2—bursting

bit 6—EVENT 1 rear panel output

bit 7—pattern reset

Because a PRAM byte has only four bits that can change states, there are only 15 possible byte patterns as shown in Table 8- 6. The table also shows the decimal value for each pattern, which is needed for downloading data using the list format shown on page 314.
