Channels tab (Source dialog)
Selecting
opens the Source dialog Channels tab. The Source Channels tab contains the controls for enabling or disabling the connected source's channels.You must first select a Configured Source to see its available channels in this tab.
Connect checkbox is selected on the Source > Control tab.
- Operation selects the source logical channel operation. This parameter is only visible when the selected source is an AWG because the only operation supported by vector sources is None. If the Operation parameter is not showing, check to make sure the- An Operation of None means the arb data for a single channel in the waveform file is downloaded to a single physical channel in the source.
- An Operation of I+jQ has two operands. The first operand is the physical channel that plays the I phase signal and the second operand is the physical channel that plays the Q phase signal of the arb waveform from one channel's data in the waveform file. If the waveform file contains data for only one channel, that channel's data is downloaded to all source logical channels. If the waveform file contains data for multiple channels, the data for a channel is downloaded to a corresponding source logical channel. The correspondence between physical channels and logical channel operands is displayed in brackets on the right of each physical channel listed on the Source Channels tab.
Default: None
Choices: None, I+jQ
- Enables or disables the available channels for the currently connected source. The number of channels that appear depends on the model of source and its installed options.
In each row, the first (left) number is the source's RF Radio Frequency: A generic term for radio-based technologies, operating between the Low Frequency range (30k Hz) and the Extra High Frequency range (300 GHz). Out channel number. The number in brackets to the right is the channel ID in a multi-channel arb waveform file associated with the source channel. For example, if a source has four channels and only the even numbered channels are enabled, source Ch2 will have [1] indicating that Ch1 in the multi-channel arb file will be downloaded to source Ch2 and source Ch4 will have [2] indicating that Ch2 in the arb file will be downloaded to source Ch4. If you download a single channel recording to a multi-channel configuration, the single channel recording is downloaded to all enabled source channels. If you want to download a single channel arb file to a single source channel, then that source channel should be the only one enabled.
At least one source channel must be enabled.
Source Control tab.
- The source channel is enabled and available for configuration in theSource Control tab.
- The source channel is disabled and will not appear in the
- The Apply button creates a source logical channel configuration using the checked (enabled) physical channels.
