Programming the Status Register System
Status Groups
Baseband Operation Condition Register
The Baseband Operation Condition Register continuously monitors the hardware and firmware status of the
signal generator. Condition registers are read only.
Baseband Operation Transition Filters (negative and positive)
The Baseband Operation Transition Filters specify which types 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).
Baseband Operation Event Register
The Baseband Operation Event Register latches transition events from the condition register as specified by
the transition filters. Event registers are destructive read only: reading data from an event register clears the
contents of that register.
Table 3-6 Baseband Operation Condition Register Bits
Bit Description
0 Baseband 1 Busy. A 1 in this position indicates the signal generator baseband is active.
1 Baseband 1 Communicating. A 1 in this bit position indicates that the signal generator baseband
generator is handling data I/O.
2–14 Unused. These bits are always set to 0.
15 Always 0.
Query:
STATus:OPERation:BASeband:CONDition?
Response: The decimal sum of the bits set to 1
Example: The decimal value 2 is returned. The decimal sum = 2 (bit 1).
Commands:
STATus:OPERation:BASeband:NTRansition <value> (negative transition), or
STATus:OPERation:BASeband:PTRansition <value> (positive transition), where
<value> is the sum of the decimal values of the bits you want to enable.
