## Command Syntax

    :MEASure:EYE:FTIMe:SOURce <rte_source>

Where <rte_source> can be one of the following:

- `ECHannel{N}` — Where N identifies a specific channel in the form "<connection1-8>_<ch1-8>" from which the real-time eye was created. With connection 1, the connection number part (that is, "1_") is optional, and you can simply use the channel number "<ch1-8>". For example, connection 4 channel 2 is `ECHannel4_2`.
- `EDIFf{N}` — Where N identifies a specific differential waveform in the form "<connection1-8>_<ch1|ch3|ch5|ch7>" from which the real-time eye was created. With connection 1, the connection number part (that is, "1_") is optional, and you can simply use the channel number "<ch1|ch3|ch5|ch7>". When two channels are paired to create a differential waveform and a common-mode waveform, the odd-numbered channel is used when specifying the waveform. For example, connection 5 differential waveform 3 (from the pairing of channels 3 and 4) is `EDIFf5_3`.
- `ECMode{N}` — Where N identifies a specific common-mode waveform in the form "<connection1-8>_<ch1|ch3|ch5|ch7>" from which the real-time eye was created. With connection 1, the connection number part (that is, "1_") is optional, and you can simply use the channel number "<ch1|ch3|ch5|ch7>". When two channels are paired to create a differential waveform and a common-mode waveform, the odd-numbered channel is used when specifying the waveform. For example, connection 5 common-mode waveform 3 (from the pairing of channels 3 and 4) is `ECMode5_3`.
- `EFUNction{1:64}`
- `EWMemory{1:8}`
- `CGMemory{1:8}` — If the Color-Grade/Gray Scale memory contains a real-time eye.
