:RDCA Subsystem

Use the :RDCA (Remote DCA) subsystem commands to establish a connection between FlexPLL and the JTF Receiver (DCA-X or DCA-M clock recovery hardware). You can establish a connection via LAN, USB, or GPIB. All N1000A DCA-X mainframes come with the GPIB card installed (opton GPI). After configuring the connection, use the :RDCA:CONNect command to make the actual connection.

Since FlexPLL can be launched from FlexDCA's Apps menu, if FlexDCA is already connected to the DCA-X or DCA-M, the Receiver connection is automatically applied to FlexPLL. The connection settings in the Remote DCA fields in the Receiver dialog will already be configured.

To configure the Receiver's CDR Setup including the input signal's symbol rate, use the commands in the :CRECovery subsystem.

Example Command Sequence

					FlexDCA.write(':RDCA:CONNect:METhod LAN') # Use LAN rather than USB or GPIB
					FlexDCA.write(':RDCA:CONNect:HOST "K-N1000A-20108"') # Specify VISA address
					FlexDCA.timeout=20000
				FlexDCA.query(':RDCA:CONNect;*OPC?') # Make connection
