Using Auto Scale, Cursors, Measurements, and Waveform Math 2
Agilent InfiniiVision 7000B Series Oscilloscopes Evaluation Guide 21
With “tracking” cursors, the voltage cursors “track” the selected
waveform based on the position of the timing cursor (X1 and X2). Let’s
now perform some automatic parametric measurements on these
waveforms.
24 Press [Meas].
25 Press Source; then, select 2.
26 Press Select; then, select Rise Time.
27 To begin executing the “Rise Time” measurement on channel 2, either
push the selection knob or press Measure Rise.
Up to four automatic parametric measurements can be selected and
displayed with a complete set of measurement statistics. Default
threshold levels for the rise and fall time measurements are set at 10%
and 90%. All other timing measurements utilize the 50% threshold levels.
If desired, threshold levels can be manually set to other relative (%) or
absolute values (V). Let’s now perform a waveform math function (FFT)
on the channel 1 waveform to determine the carrier frequency of this
amplitude-modulated signal.
