以编程方式设置多个Delta时间测量

我想向示波器发送命令以进行两次（或更多次）不同的Delta time测量，但似乎只允许一次。
任何设置第二个的尝试都会改变第一个。
第一次测量......：MEAS：DELT CHAN3，CHAN2;
：MEAS：DELT：DEF RIS，1，UPP，RIS，1，MIDD;
：MEAS：NAME MEAS1，“3r-2r”...尝试第二次测量......：MEAS：DELT CHAN3，CHAN2;
：MEAS：DELT：DEF RIS，1，UPP，FALL，1，MIDD;
：MEAS：NAME MEAS1，“3r-2f”......但它只是覆盖了第一个。
这可以通过UI完成，但我想以编程方式进行设置。
任何人都知道这种明显的限制是否有解决办法？

  I'd like to send commands to the scope to take two (or more) different Delta Time measurements, however it seems that only one is allowed. Any attempt to set up a second one just alters the first one.

First Measurement...
:MEAS:DELT CHAN3, CHAN2; :MEAS:DELT:DEF RIS, 1, UPP, RIS, 1, MIDD; :MEAS:NAME MEAS1, "3r-2r"

...try the Second Measurement...
:MEAS:DELT CHAN3, CHAN2; :MEAS:DELT:DEF RIS, 1, UPP, FALL, 1, MIDD; :MEAS:NAME MEAS1, "3r-2f"

...but it just overwrites the first one.

This can be done through the UI, but I'd like to set this up programmatically. Anyone know if there's a work-around for this apparent limitation?
