CURSORS READOUT

VOLT

 

 

Three readouts can be selected:

-ΔV: Gives the voltage difference between the cursors.

-V1 V2: Gives the absolute voltage with respect to ground for each cursor. V1 and V2 have to be selected separately.

-ΔV-ratio: The readout is a

percentage that can be reset using the ’Δ=100 %’ softkey. This can be used for amplitude comparisons. The figure shows an example: the percentage of overshoot compared with 100 % pulse amplitude is determined.

Softkey pair to switch between time readout ΔT, 1/ΔT, ΔT-ratio, phase, and T-trg.

Toggle function softkey to switch between voltage readout ΔV, V1, V2 or ΔV-ratio.

Softkey to reset ΔV-ratio to 100%, ΔT-ratio to 100% or phase to 360°.

Toggle function softkey to link the TRACK control to both cursors or to the track cursor only.

Toggle function softkey to switch between time or volt cursor for 100% reset and positioning.

Remote commands:

CPL: QM (command to query measured values)
