Standard Operation Condition Register
The Standard Operation Condition Register continuously monitors the hardware and
firmware status of the signal generator. Condition registers are read only.
Table 3-5 Standard Operation Condition Register Bits
Bit Description
0 I/Q Calibrating. A 1 in this position indicates an I/Q calibration is in process.
1 Settling. A 1 in this bit position indicates that the signal generator is settling.
2 Unused. This bit position is set to 0.
3 Sweeping. A 1 in this bit position indicates that a sweep is in progress.
4 Measuring. A1 in this bit position indicates that a bit error rate test is in progress
5 Waiting for Trigger. A 1 in this bit position indicates that the source is in a “wait for
trigger” state. When option 300 is enabled, a 1 in this bit position indicates that
TCH/PDCH synchronization is established and waiting for a trigger to start
measurements.
6,7,8 Unused. These bits are always set to 0.
9
DCFM/DCφM Null in Progress. A 1 in this bit position indicates that the signal
generator is currently performing a DCFM/DCΦM zero calibration.
10 Baseband is Busy. A 1 in this bit position indicates that the baseband generator is
communicating or processing. This is a summary bit. See the “Baseband Operation
Status Group” on page 122 for more information.
11 Sweep Calculating. A 1 in this bit position indicates that the signal generator is
currently doing the necessary pre-sweep calculations.
12 BERT Synchronizing. A 1 in this bit position is set while the BERT is synchronizing
to ‘BCH’, then ‘TCH’ and then to ‘PRBS’.
12, 13, 14 Unused. These bits are always set to 0.
15 Always 0.
Query:
STATus:OPERation:CONDition?
Response: The decimal sum of the bits set to 1
Example: The decimal value 520 is returned. The decimal sum = 512 (bit 9) + 8 (bit 3).
