Class interface

Attributes:

Name Description
IdnScalar: DevString Instrument identification
QueryWindowScalar: DevUShort When many attributes are requested at the same time, they are grouped in subqueries of this size
TimeStampsThresholdScalar: DevFloat This value sets the threshold time to use a cached value or hardware read it

Commands:

Name Description
StateInput: DevVoid
Output: State
Device state		 This command gets the device state (stored in its device_state data member) and returns it to the caller.
StatusInput: DevVoid
Output: ConstDevString
Device status		 This command gets the device status (stored in its device_status data member) and returns it to the caller.
IDNInput: DevVoid
Output: DevString		 Request identification to the instrument.
StartInput: DevVoid
Output: DevBoolean		 Start an active monitoring.
StopInput: DevVoid
Output: DevBoolean		 Stop the active monitoring.
OnInput: DevVoid
Output: DevBoolean		 Allow communication with the instrument.
OffInput: DevVoid
Output: DevBoolean		 Release the communication with the instrument.
ExecInput: DevString
Output: DevString		 evaluate python code inside the device server. This command can be very helpful and dangerous.
AddMonitoringInput: DevString
Output: DevBoolean		 Add an attribute to the list of monitored attributes
RemoveMonitoringInput: DevString
Output: DevBoolean		 Remove an attribute from the list of monitored attributes
SetMonitoringPeriodInput: DevVarStringArray
Output: DevBoolean		 From the list of already monitored attributes, stablish (or change) the period that it is checked.
GetMonitoringPeriodInput: DevString
Output: DevFloat		 Get the period that is checked an attribute monitored.
CMDInput: DevString
Output: DevString		 Expert command for a direct send of a SCPI command and read the answer.
CMDfloatInput: DevString
Output: DevVarFloatArray		 Expert command for a direct send of a SCPI command and read the answer converted to a float list.
StandbyInput: DevVoid
Output: DevBoolean		 Stablish communication with the instrument.

Name Description

Properties:

Name Description
InstrumentDevString The name of the instrument to use
PortDevUShort In case of socket interface the port value can be changed
NumChannelsDevUShort Number of channels available in the instrument, if it has
NumFunctionsDevUShort Number of functions available in the instrument, if it has
MonitoredAttributesArray of DevString When the device is in RUNNING state, the attributes listed here will be monitored (having events) with a period said in the attribute TimeStampsThreashold (or different if specified with a : separator after the attrName)
AutoOnDevBoolean When device startup, try an on() to connect to the instrument authomatically
AutoStartDevBoolean When device startup, try an Start() to monitor attributes, if MonitoredAttributes is configuredc, authomatically
AutoStandbyDevBoolean When device startup, try an standby() to connect to the instrument authomatically.
