This topic shows the configurations that can be used for controlling FlexDCA.

The DCA-X rear-panels include LAN and GPIB connectors for remote control. Rear-panel Type A USB connectors can be used for connecting to and controlling a DCA-M module. Your script can send SCPI commands to the DCA-M module when the script is running on the DCA-X. You cannot send SCPI commands from a PC through the DCA-X to a DCA-M.

N1000A DCA-X	86100D DCA-X

You can remotely control a DCA-X via the LAN or GPIB. Refer to the programming quick start guide to learn how to establish control over the LAN. The programming commands are fully documented in this help system. Use the SCPI Server Setup dialog box to configure the instrument to receive remote programming commands.

Configuration 1. FlexDCA on PC Controlling FlexDCA on DCA-X

In this configuration, your script is sending commands to FlexDCA on the PC which, in turn, is linked to FlexDCA on a DCA-X oscilloscope. This is know as a Flex-on-Flex connection where the N1000A DCA-X is installed as an extended module toe FlexDCA on the PC.

Configuration 2. FlexDCA Offline

In this configuration, your script is sending commands to FlexDCA on the PC. Use this configuration when hardware is not available. FlexDCA Offline can perform measurements on imported waveforms or waveforms created by simulated optical or electrical receiver modules. This configuration is also a good choice in cases when hardware is not available yet you want to start developing your program.

Configuration 3. Script on PC Controlling an N1000A DCA-X

In this configuration, your script is running on your PC while sending commands to a remote DCA-X oscilloscope over LAN.

Configuration 4. Script on DCA-X. Controlling DCA-X Without PC

In this configuration, your script is running on the DCA-X. In this situation, there is no Flex-on-Flex connection so both the DCA-X modules and DCA-M extended modules can be controlled by your script.

To determine FlexDCA's current configuration

The following table lists the queries that you can send to learn about the current configuration of FlexDCA. The queries have command forms that you can use to change the configuration gracefully without using a default setup.

Query Responses Indicating FlexDCA Configuration

Query	Configurations						Description
	Queries sent to N1010A on PC			Queries sent to DCA-X		temp
	Offline	Offline with DCA assigned1	Flex-on-Flex	DCA-X	DCA-X with Flex-on-Flex2	FlexEye
*IDN?	N1010A	N1010A	86100D	86100D	86100D		These responses are substrings of the returned identificaton string. For example, Keysight Technologies,N1010A,2UA5383S5F,P.05.60.254
:SYStem:HAL?	DSCP	DSCP	DSCP	DCA86100	DCA86100	FEYE	Indicates state of FlexDCA's Hardware Abstraction Layer (HAL).
:RDCA:CONNect:STATe?	NCON	NCON	CONN	NCON	NCON		State of connection between N1010A and an DCA-X.
:EMODules:SLOT1:SELection?	EMPT3	DCA	DCA	DCA	DCA		Indicates, in this case DCA-X, that the DCA is assigned to slot 1. With N1010A used offline, DCA can be assigned to slot 1 but not connected. In this case, use the :EMODules:SLOT1:SELection EMPTy command to free up slots 1 through 4 for DCA-M series modules or simulated modules.
:EMODules:SLOT1:STATe?	NCON	NCON	CONN	CONN	NCON		Indicates communication connection has been established with an extended module.
Footnotes:
1. Program is connected to N1010A FlexDCA that has an DCA-X assigned to slots 1 through 4 but not connected.
2. Program is connected to an DCA-X that has a Flex-on-Flex connection from an N1010A.
3. Returned values can also be DEM, DOM, OEM, or QEM for simulated module or DCAM for DCA-M M-series module.
