(Write-only) Adds an external device to the list of configured devices.  This is the same as pressing New on the Select an external device dialog.

Upon creation, all settings on the new device are set to the defaults. The device is not active until set using SYST:CONF:EDEV:STAT

Parameters

<name>

String - Model and type of the external device.

To see a list of configured external devices, use SYST:CONF:EDEV:CAT?

Examples

SYST:CONF:EDEV:ADD "myDevice"

system:configure:edevice:add "myDevice"

Query Syntax

Not Applicable

Default

Not Applicable

(Read-only) Returns a list of names of all configured devices. These are devices that appear in the external devices dialog.

Use SENS:FOM:CAT? to report all active devices.

Use Source:CAT? to report all active sources.

Parameters

None

Example

SYST:CONF:EDEV:CAT?

system:configure:edevice:cat

Return Type

String of comma-separated devices. "Device0:Driver0, Device1:Driver1"

Default

Not applicable

(Read-Write) Sets and returns the external device driver (model).

Parameters

<name>

String - Name of the device.

<value>

String - External device driver (model). Choose from the following:

"AGPM" for all power meters.

"AGPULSEGEN" for supported pulse generators.

"DCSource" for all supported DC Sources

"DCMeter" for all supported DC Meters

See a list of supported external source drivers.

Examples

SYST:CONF:EDEV:DRIV "myDevice","AGPM"

system:configure:edevice:driver "myDevice","AGESG"

SYSTem:CONFigure:EDEVice:DRIVer? <name>

Return Type

String

Default

"AGGeneric"

(Read-Write) Sets and returns the Device Type for the external device.

Parameters

<name>

String - Name of the device to modify.

<type>

String - Device type - not case sensitive. Choose from:

"Source" - external source

"Power Meter" - power meter

"DC Meter" - DC voltmeter

"DC Source" - DC power supply

"Pulse Generator" - external pulse generator

Examples

SYST:CONF:EDEV:DTYP "myDevice","Power Meter"

Query Syntax

SYSTem:CONFigure:EDEVice:DTYPe? <name>

Return Type

String

Default

None

(Read-only) Returns whether the named device is present on the bus for which it is configured.

Parameters

<string>

Name of the external device.

Example

SYST:CONF:EDEV:EXIS? "MyPowerMeter"

Return Type

Boolean

• 0 - The device is not in the collection or the device fails to respond and times out when communication is attempted.

• 1 - The device responds when communication is attempted.

Default

Not applicable

(Read-Write) Sets and return the configuration path for the specified external device.

Parameters

<name>

String - Name of the device.

<value>

String - Configuration path. Any valid VISA resource shown in the IO Configuration field of the external devices dialog, enclosed in quotes.

Do NOT use the ID string of a PMAR USB power sensor as the resource string. The ID string is returned by SYST:COMM:USB:PMET:CAT?

Examples

SYST:CONF:EDEV:IOC "myDevice","GPIB0::13::INSTR"

system:configure:edevice:ioconfig "myDevice","GPIB0::13::INSTR"

Query Syntax

SYSTem:CONFigure:EDEVice:IOConfig? <name>

Return Type

String

Default

" " Empty String

(Read-Write)  Enable or disable communication with an external device.

When disabled (OFF), the PNA will NOT attempt to connect to the external device regardless of the instrument state command (SYST:CONF:EDEV:STATe).  Therefore, no errors will be produced if the device is not connected.

This command is useful for debugging and testing states when the external device is not connected. This command is unnecessary in ordinary operation (when the device is connected).

Parameters

<name>

String - Name of the device.

<value>

Boolean - Choose from:

OFF or 0 - Device communication disabled

ON or 1 - Device communication enabled

Examples

SYST:CONF:EDEV:IOEN "myDevice", ON

system:configure:edevice:ioenable "myDevice", 0

Query Syntax

SYSTem:CONFigure:EDEVice:IOENable? <name>

Return Type

Boolean

Default

ON

(Write-only) Recalls an external device configuration file from the PNA hard drive.

Currently, only DC Supply and DC Meter configuration files are supported. See more DC Device commands.

Use SYST:CONF:EDEV:SAVE to save a configuration file.

Parameters

<file>

String - Filename of the external device configuration file.

1. If <file> is not a full path, it is assumed to be a relative path based at "D:\Drivers".

2. The file specified using <file> cannot be the same file as "D:\Drivers\<name>.xml".

<name>

String - Name of the external device. Currently, only DC Supply and DC Meter configuration files are supported.

Examples

SYST:CONF:EDEV:LOAD "D:\Drivers\MyConfigFile.xml","MyDevice"

Query Syntax

Not Applicable

Default

Not Applicable

(Write-only) Removes the specified device from the list of configured devices.  If the device is a Source and both Active and I/O Enabled is checked (ON), then the RF power state is set to OFF. Learn more.

Parameters

<name>

String - Name of the device. Not case sensitive. Use SYST:CONF:EDEV:CAT? to return a list of configured devices.

Examples

SYST:CONF:EDEV:REM "myDevice"

system:configure:edevice:remove "myDevice"

Query Syntax

Not Applicable

Default

Not Applicable

(Write-only) Saves an external device configuration file to the PNA hard drive.

Currently, only DC Supply and DC Meter configuration files are supported. See more DC Device commands.

Use SYST:CONF:EDEV:LOAD to recall a configuration file.

Parameters

<file>

String - Filename of the external device configuration file.

<name>

String - Name of the external device.  Currently, only DC Supply and DC Meter configuration files are supported.

(Read-Write)  Set and return the state of activation of the device. When SYST:CONF:EDEV:IOEN = ON, and this command is set to ON, the PNA will attempt communication with the external device.

Send this command AFTER sending other external device settings (especially SYST:CONF:EDEV:DTYP) to avoid communicating with the device before it has been fully configured.

Return Type

Boolean

Default

OFF - When configured using the front panel user interface, the device is ON (activated) by default.

(Read-Write) Set and return the time out value for the specified external device. This is the time allowed for communication with the device before an error is generated.
