Hardware
Manufacturer: none
Bus: Socket
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. |
Pipes:
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. |
