## Command Syntax

    :MEASure:LIST:ITEM{N}:SOURce{1|2} <source_waveform>

Where {N} is a number from 1 to 64 that identifies a measurement row in the Results table. For example, `ITEM4`.

Where <source_waveform> can be one of the following:

- `CHANnel<connection1-8>_<ch1-8>`; With connection 1, the "`1_`" part is optional, and you can simply use `CHANnel<ch1-8>`.
- `DIFF{1:4}`
- `WMemory{1:8}`
- `FUNCtion{1:64}`

## Query Syntax

    :MEASure:LIST:ITEM{N}:SOURce{1|2}?

## Query Response

    <source_waveform>

## Description

Changes the source waveform of an existing measurement in the Results table. The item number identifies the measurement in the table. The measurement's identifying item number starts at 1 at the top of table and increment down the table. If more that one measurement is displayed per row, the measurements are numbered starting at the tables top-left corner and is incremented row-column ending in the tables bottom right corner.

The `:MEASure:LIST:SELect` command is not related to this task.

For most measurements, a single input waveform is used and is selected by the command's `:SOURce1` node. Some measurements, such as `:MEASure:HORizontal:DTIMe` have two input waveforms. In this case, send this command twice, the first time with `:SOURce1` and the second time with `:SOURce2`.

Follow this command with the `:SYSTem:AUToscale` and `*OPC (Operation Complete)` commands.

## Example Command Sequence

To change the source waveforms of an existing Delta Time measurement in the second row of the Results table. The delta time measurement is made on two different sets of source waveforms.

    :MEASure:HORizontal:DTIMe:SOURce1 CHAN1_1
    :MEASure:HORizontal:DTIMe:SOURce2 CHAN1_2
    :MEASure:HORizontal:DTIMe  # delta time on table row 1
    :MEASure:HORizontal:DTIMe?
    :MEASure:HORizontal:RTIMe:SOURce1 CHAN1_1
    :MEASure:HORizontal:RTIMe  # delta time moves to table row 2

    ...

    :MEASure:LIST:ITEM2:SOURce1 CHAN5_1  # change sources in table
    :MEASure:LIST:ITEM2:SOURce2 CHAN5_2
    :SYSTem:AUToscale;*OPC?
    :MEASure:HORizontal:DTIMe:SOURce1 CHAN5_1  # match sources in table
    :MEASure:HORizontal:DTIMe:SOURce2 CHAN5_2
    :MEASure:HORizontal:DTIMe
    :MEASure:HORizontal:DTIMe?
