Programming the Status Register System

Status Groups

Chapter 3120

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.

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).
