200 Keysight CXG, EXG, and MXG X-Series Signal Generators Programming Guide
Programming the Status Register System
Status Groups
Data Questionable BERT Condition Register
The Data Questionable BERT Condition Register continuously monitors the
hardware and firmware status of the signal generator. Condition registers are
read only.
Data Questionable BERT Transition Filters (negative and positive)
The Data Questionable BERT Transition Filters specify which type of bit state
changes in the condition register set corresponding bits in the event register.
Changes can be positive (0 to 1) or negative (1 to 0).
Table 4-8
Data Questionable BERT Condition Register Bits
Bit
Description
0
No Clock
. A 1 in this bit position indicates no clock input for more than 3 seconds.
1
No Data Change
. A 1 in this bit position indicates no data change occurred during the last 200 clock signals.
2
PRBS Sync Loss
. A 1 is set while PRBS synchronization is not established.
*RST
sets the bit to zero.
3
−
14
Unused
. These bits are always set to 0.
15
Always 0.
Query:
STATus:QUEStionable:BERT:CONDition?
Response:
The
decimal
sum of the bits set to 1.
Commands:
STATus:QUEStionable:BERT:NTRansition <value>
(negative transition), or
STATus:QUEStionable:BERT:PTRansition <value>
(positive transition), where
<value>
is the sum of the decimal values of the bits you want to enable.
Queries:
STATus:QUEStionable:BERT:NTRansition?
