DCA-M Timebase Cal Commands

Command Syntax

:CALibrate:TIMebase:SLOTN:STARt

Where N identifies a specific DCA-M N109x-series module by slot and must be selected from {1:8}.

Description

For a DCA-M module in the indicated slot, starts a N109x-series Timebase Calibration. The following table lists the input clock signal requirements for the calibration waveform. The source of the calibration waveform must be a calibrated microwave or vector signal generator. Do not use a pattern generator or arbitrary waveform generator. When the calibration starts, the DCA-M automatically switches to oscilloscope mode.

Connect the signal to an DCA-M's electrical channel input and to the front-panel Clock In input. Use the :CALibrate:TIMebase:SLOT:CHANnel command to specify the input channel. After performing the calibration.

Clock Signal Requirements
DCA-M Frequency Amplitude
N109x-series 26.000000 GHz 100 mVpp to 700 mVpp

Requires FlexDCA revision A.03.00 and above.
