MSO44 scope SCPI phase meas questions

Hi,&#160;<br> I want to use SCPI to measure phase delay from D0 to D1 of ch4. I have TLP058 logic probes plugged into ch4.&#160;<br> I have tried the below SCPI cmds but they aren't working so I'm guessing I'm missing a space here/there?<br> <br> MEASUrement:MEAS1:type phase<br> MEASUrement:MEAS1:SOUrce1 CH4D_0<br> MEASUrement:MEAS1:SOUrce2 CH4D_1

Hi Xiang,<br> <br> You'd generally start with the <code>measurement:addmeas phase</code> command, followed by your configuration commands.<br> I would also suggest doing <code>*ESR?</code> to check for errors every time you send a command.&#160; &#160;

my question is are these below cmds correct?&#160;<br> if not, what should they be?&#160;<br> <br> <br> MEASUrement:MEAS1:SOUrce1 CH4D_0<br> MEASUrement:MEAS1:SOUrce2 CH4D_1

<p>HI Xiang,</p> <p></p> <p>No, the arguments should be &quot;CH4_D0&quot; instead of &quot;CH4D_0&quot;.</p> <p>You can always test this by setting the measurement manually on the machine and then querying the command of interest like so: <code>MEASUrement:MEAS1:SOUrce1?</code></p>
