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 4-5 Standard Operation Condition Register Bits

Bit

Description

 

 

0a

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 always set to 0.

 

 

3

Sweeping. A 1 in this bit position indicates that a sweep is in progress.

 

 

4b

Measuring. A 1 in this bit position indicates that a bit error rate test is in progress.

 

 

5c

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.

 

 

9d

DCFM/DCφM Null in Progress. A 1 in this bit position indicates that the signal generator is

 

currently performing a DCFM/DCΦM zero calibration.

 

 

10c

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 162 for more information.

 

 

11e

Sweep Calculating. A 1 in this bit position indicates that the signal generator is currently doing

 

the necessary pre- sweep calculations.

 

 

12b

BERT Synchronizing. A 1 in this bit position is set while the BERT is synchronizing to ‘BCH’,

 

then ‘TCH’ and then to ‘PRBS’.

 

 

13, 14

Unused. These bits are always set to 0.

 

 

15

Always 0.

 

 

a.In the N5181A, 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 N5181A and N5182A this bit is always set to 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).
