STATus:OPERation[:EVENt]?
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
