Syntax
STATus:OPERation[:EVENt]?
Description
This command queries the event register for the Standard Operation Register group.

For more information on the SCPI Status System for the Agilent 34980A, see the Status System Diagram. |
Used With:
34921A through 34925A Multiplexer Modules
34950A Digital I/O Module (digital input and counter channels only)
34952A Multifunction Module (digital input and totalizer channels only)
Remarks
The following table lists the bit definitions for the Standard Operation Register.
|
Bit Number |
Decimal Value |
Definition | |
|
0 |
Calibration in Progress |
1 |
Instrument is performing a calibration. |
|
1-3 |
Not Used |
Not Used |
"0" is returned. |
|
4 |
Measurement in Progress, or Measuring |
16 |
Instrument is making a measurement as part of a scanning operation or as a standalone DMM measurement. The bit goes true when the INITiate operation begins, and goes false when the INITiate operation ends. |
|
5 |
Waiting for Trigger |
32 |
Instrument is waiting for an external trigger. |
|
6-7 |
Not Used |
Not Used |
"0" is returned. |
|
8 |
Configuration Change |
256 |
This bit is set when anything related to a channel configuration
or measurement is changed. |
|
9 |
Memory Threshold |
512 |
Programmed number of readings have been stored in reading memory (see DATA:POINts:EVENt:THR command). |
|
10 |
Instrument Locked |
1024 |
If a remote thread (GPIB, USB, or LAN) has a lock (see SYSTem:LOCK:REQuest? command), this bit will be set. When a remote thread releases the lock (see SYSTem:LOCK:RELease command), this bit will be cleared. |
|
11-13 |
Not Used |
Not Used |
"0" is returned. |
|
14 |
Sequence Running |
16384 |
A sequence is currently running. The bit goes true at the beginning of the execution of the sequence, and goes false when the sequence has completed. |
|
15 |
Not Used |
Not Used |
"0" is returned. |
Once a bit is set, it remains set until cleared by reading the event register or the *CLS (clear status) command.
Return Format
The command reads the event register and returns a decimal value which corresponds to the binary-weighted sum of all bits set in the register. For example, if bit 4 (decimal value = 16) and bit 8 (decimal value = 256) are set, this command will return "+272".
Example
The following command reads the event register (bit 8 is set).
STAT:OPER?
Typical Response: +256
