:SLOT Subsystem
The Slot (:SLOT) subsystem has two SCPI nodes :SLOT:TRIGger and :SLOT:SWITch. The nodes are listed in two navigation panels in this topic: DCA-M Trigger Commands and Optical Switch Commands. As noted in the command topics, always include in the SCPI command the slot number where the DCA-M or switch is installed.
DCA-M Trigger Settings
Use the :SLOT:TRIGger SCPI node commands to control the trigger settings of DCA-M oscilloscopes such as the N1090A, N1092A/B/C/D/E, and N1094A/B. These commands configure the settings in the Trigger Setup dialog's N109x (Slot X) Trigger tab. To configure settings for the Trigger Setup dialog's General Trigger Setup or Advanced Trigger Setup tabs, use the commands in the :TRIGger subsystem. For example, with an N1092A in slot 2:
:TRIGger:PLOCk ON;*OPC? :SLOT2:TRIGger:SRATe:AUTodetect OFF :SLOT2:TRIGger:SRATe 1.4025E+10 :SLOT2:TRIGger:DCDRatio:AUTodetect OFF :SLOT2:TRIGger:DCDRatio:TYPE INTeger :SLOT2:TRIGger:DCDRatio SUB8 :SLOT2:TRIGger:PLENgth:AUTodetect OFF :SLOT2:TRIGger:PLENgth: 1023
If you turn the DCA-M's Shared Pattern Parameters setting on (:SLOT:TRIGger:TRACKing command), all settings in the Pattern Lock tab will automatically set and configure the settings in the N109x (Slot X) Trigger tab. If you use multiple DCA-Ms, this feature allows you to quickly ensure that all pattern locking settings are the same for each DCA-M. The shared parameters are symbol rate, clock divide ratio, and pattern length. For example, with an N1092A in slot 2 and an N1092B in slots 3 and 4:
:TRIGger:PLOCk ON;*OPC? :TRIGger:SRATe:AUTodetect OFF :TRIGger:SRATe 1.4025E+10 :TRIGger:DCDRatio:AUTodetect OFF :TRIGger:DCDRatio:TYPE INTeger :TRIGger:DCDRatio SUB8 :TRIGger:PLENgth:AUTodetect OFF :TRIGger:PLENgth: 1023 :SLOT2:TRIGger:TRACking ON :SLOT3:TRIGger:TRACking ON :SLOT4:TRIGger:TRACking ON
Optical Switch Control
Use the :SLOT:SWITch SCPI node commands to connect optical switch paths (routes) on a supported and connected optical switch. You can also run a pass/fail test that verifies each optical path through the switch. Use these command to troubleshoot switch paths. The :SLOT:SWITch commands must be sent to FlexDCA and not to the FlexOTO application.
Always use the FlexOTO's switch commands when using the FlexOTO application.
Up to 32 routes (paths) can be configured using the :SLOT:SWITch:ROUTe command depending on the maximum licensed switch paths in the optical switch.
Use the :SLOT:SWITch:ROUTe:LISt? query to return a comma separated list of all ports on the switch.
Use the :SLOT:SWITch:GROup:ROUTe:VSET? child query to return, for a specified input port, a comma separated list of all disconnected (available) ports. Or, for a specified output port, the state of the port (connected or disconnected).
You can run a test that verifies the integrity of a switch path using the :SLOT:SWITch:VERify:CHANnel and :SLOT:SWITch:VERify:STARt commands.
If the connected switch includes an internal tunable optical filter, use the :SLOT:SWITch:WAVelength command to to select the wavelength setting.
Supports automatic detection via USB by FlexOTO.
Third-party optical switches are not provided by Keysight and must be purchased from their manufacturer. The N1002A, when purchased as part of a solution bundle includes an optical switch. If the N1002A is purchased separately, not in a solution bundle, the Keysight switch, if desired, must be separately purchased.
When FlexDCA is running on a DCA-X, slots 5 through 8 are available for extended hardware modules. When FlexDCA is running on a PC, slots 1 through 8 are available unless a connection has been established with a DCA-X. In this case, the DCA-X consumes slots 1 through 4.
This subsystem Requires FlexDCA revision A.05.00 and above for :SLOT:TRIGger commands and revision A.07.00 and above for :SLOT:SWITch commands.
