Histogram Commands

Command 

:HISTogram:WINDow:SOURce[?] {CHANnel<number> |

FUNCtion<number> | RESPonse<number> |
WMEMory<number> | FFT}

Selects the source of the histogram window. The histogram window will track
the source’s vertical and horizontal scale.

<number>

For channels: an integer, 1 through 4, indicating the slot in which the channel
resides, followed by an optional A or B identifying which of two possible
channels in the slot is being referenced. For functions: 1 or 2. For waveform
memories (WMEMory): 1, 2, 3, or 4. For TDR response: 1, 2, 3, or 4.
