Configure Channels

Applies to N5186A only.

Available Configurations

Configurations are available to provide easy setup for various signal-generation use cases. Configurations are applicable for instruments with Option PCH.

Configuration

Description

Availability with Option PCH
Independent

For N5186A:

After Synchronization Alignment has been run, RF is repeatably coherent and triggering can be synchronized using Global Trigger.

N5186A

Tx Coherent RF is coherent, and Basebands (arbs) are always synchronized.

N5186A

Without PCH, the configuration options are limited.

Configuration

Description

Availability without Option PCH
Independent Nothing is coherent or synchronized.

N5186A

When Independent is selected, each RF channel has its own Signal block where you can select or generate a waveform to play on each path.

When 2 Tx Coherent or 4 Tx Coherent is selected, one signal is connected to two or four RF channels, respectively. When Signal Mode is Waveform, Analog Modulation or Single Tone, the same waveform data is played on all paths.

For instruments with multiple RF channels and Option PCH, configurations will be assigned by "Grouping" RF Output channels by your signal generation use case:

GUI Location

System Menu > Configure Channels

SCPI Command

[:SOURce]:CONFigure:GROups <enum_list>

[:SOURce]:CONFigure:GROups?

SCPI Example

CONF:GRO TX2

CONF:GRO?

Preset

IND for 1 Channel instrument

IND,IND for 2 Channel instrument

IND,IND,IND,IND for 4 Channel instrument

State Saved

Yes

Notes

The <enum list> is a set of enumerations separated by commas. The maximum elements of the list is the total numbers of channels of the instrument. The list will contain fewer elements than total channels when the selected group comprises more than one channel. The enumeration choices are:

INDependent

TX2

TX4

This SCPI command is not additive; sending it clears the system’s previous configuration and groups the RF Channels by the configuration options contained in the command. RF Channels that are not provided for are automatically set to Independent. Commands that try to consume more than the available number of RF Channels are not accepted, generating an error.

Querying this command returns a comma separated list, each entry being a particular Group’s configuration, starting with Group 1.

TX2 & TX4 are available with Option PCH

For N5185A:

Attempting to change value raises error 224,"Illegal parameter value".

Group Count

Remote command only.

Query only command. Returns the total number of Groups in the selected configuration.

SCPI Command

[:SOURce]:GROup:COUNt?

SCPI Example

GRO:COUN?

Notes

The maximum number of Groups is equal to the total number of RF Outputs available to a system.

State Saved

No

Group Configuration

Remote command only.

Query only command. Returns a particular Group’s configuration.

SCPI Command

[:SOURce]:GROup<group>:CONFiguration?

SCPI Example

GRO1:CONF?

Notes

Querying Groups that are not part of the selected configuration will Error.

State Saved

No

Group Signal Count List

Remote command only.

Query only command. Returns a comma separated list containing the signal count of each Group in the selected configuration.

SCPI Command

[:SOURce]:GROup:SIGNal:COUNt:LIST?

SCPI Example

GRO:SIGN:COUN:LIST?

Notes

The list entries are the signal count for each Group, starting with Group 1.

State Saved

No

Group Signal Count

Remote command only.

Query only command. Returns the total number of signals within a particular Group in the selected configuration.

SCPI Command

[:SOURce]:GROup<group>:SIGNal:COUNt?

SCPI Example

GRO1:SIGN:COUN?

Notes

Querying Groups that are not part of the selected configuration will Error.

State Saved

No

Signal Count

Remote command only.

This query command returns the number of signal blocks available in the selected configuration.

In instruments without Option 8SG, the maximum number of signals is 1 per configuration group. With Option 8SG, the number of signals is dependent on the configuration of the group: for example, if the configuration group is Independent, then 8 signals are available.

SCPI Command

[:SOURce]:GROup<group>:SIGNal:COUNt?

Notes

The list entries are the specific RF Channels being consumed by the specified Group.

Querying Groups that are not part of the selected configuration will Error.
