Command Syntax

:CALibrate:SKEW:SLOT{1:8}:STARt

Where the required specifier {1:8} identifies a specific module by slot number. For a module that occupies multiple slots, use the module's left-most slot number to identify the module. For two-slot modules, the slot number would be 1 or 3. For four-slot modules like the 86108B, the slot number would be 1.

Description

For N1000-series plug-in modules (for example, N1045A), DCA-M modules (for example, N1094A/B), and an 86118A-H01 modules, starts a horizontal skew calibration on the indicated slot (module). This calibration removes any difference in the electrical lengths between the module's two remote sampling head cables. You must connect a 1.0 GHz sine wave to one of the input channels and a synchronous trigger to the DCA-X's front-panel Trigger input. The amplitude of the signal must be between 200 mV (−10.0 dBm) and 710 mV (1.0 dBm). The *OPC? query should be used to detect when a portion of the calibration has completed. Use the :CALibrate:CONTinue command to dismiss dialogs that are displayed during a calibration.

During the calibration, always use same cables and connectors to connect the source to each of the module's channels.

Requires FlexDCA revision A.02.00 and above.
