Programming the Status Register System
Status Groups
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 4-6 Standard Operation Condition Register Bits
Bit Description
a I/Q Calibrating. A 1 in this position indicates an I/Q calibration is in process.
0
1 Settling. A 1 in this bit position indicates that the signal generator is settling.
2 Unused. This bit position is always set to 0.
3 Sweeping. A 1 in this bit position indicates that a sweep is in progress.
b Measuring. A 1 in this bit position indicates that a bit error rate test is in progress.
4
c Waiting for Trigger. A 1 in this bit position indicates that the source is in a "wait for trigger"
5
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.
d
DCFM/DCφM Null in Progress. A 1 in this bit position indicates that the signal generator is
9
currently performing a DCFM/DCΦM zero calibration.
Baseband is Busy. A 1 in this bit position indicates that the baseband generator is
c
10
communicating or processing. This is a summary bit. See the
Group" on page 187
Sweep Calculating. A 1 in this bit position indicates that the signal generator is currently doing
e
11
the necessary pre- sweep calculations.
b BERT Synchronizing. A 1 in this bit position is set while the BERT is synchronizing to 'BCH',
12
then 'TCH' and then to 'PRBS'.
13, 14 Unused. These bits are always set to 0.
15 Always 0.
a
In the N5161A/81A, E4428C, E8257D, and E8663B, this bit is always set to 0.
b
Always set to 0 if Option UN7 not present (E4438C only).
c
Option 300 is only available on the E4438C.
d
This bit is always set to 0.
e
In the N5161A/81A and N5162A/82A this bit is always set to 0.
