Data Transfer Troubleshooting (N5182A, E4438C and E8267D Only)

Table 8-13 PRAM Download - Symptoms and Causes

Symptom

Possible Cause

 

 

 

PRAM download exceeds the size of PRAM memory.

ERROR - 223, Too much data

Either use a smaller pattern or get more memory by ordering the appropriate

 

hardware option.

 

 

Data Requirements

The signal generator requires a file with a minimum of 60 bytes

For every data bit (bit 0), you must provide 7 bits of control information (bits 1- 7).

0

Data

0/1

This is the data (payload) bit. It is “unspecified” when burst (bit 2) is set to 0.

 

 

 

 

1

Reserved

0

Always 0

 

 

 

 

 

2

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.

Always 0

 

 

 

 

6

EVENT1

0/1

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.

 

 

 

 

 

7

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.
