I'm using a TDS754 scope which I know is obsolete. I'm trying to perform a remote measurement. I need to make a Reverse Recovery Measurement of a diode called TRR. It is essentially a Delay measurement. This measurement will be on one signal on channel one only. I want to set cursor1 at -.05v of the first negative falling edge and set cursor2 at the first positive rising edge of that same signal at -.06v. Then I want to measure the Delay time between those 2 voltage points which I expect to be about 2.5ns. I have attached a waveform. I am using Agilent VEE pro for software. I currently have all the preset-up conditions in my software and I am able to easily set waveform remotely in the center of the scope display with correct timebase, volts/divs, trigger etc. I cannot use one of the standard 8 measurements offered on the front panel as none of these measurements including Delay measurement allow me to make this measurement. Please help?

Consider using a Negative Width measurement and using the cursors to gate it to the portion of the waveform you are interested in. You can find information on this measurement on page B-11 of the user manual.
