Using Auto Scale, Cursors, Measurements, and Waveform Math 2
Agilent InfiniiVision 7000B Series Oscilloscopes Evaluation Guide 19
When [Auto Scale] is pressed, the oscilloscope automatically turns on
and optimally scales (V/div) for all channels that have signal activity…
including digital channels. Triggering is set to the standard “edge” mode
on the highest analog channel number, which is channel 2 in this demo
example. The timebase is set to display at least two cycles of the trigger
source channel, which is based on channel 2 in this demo example. Let’s
now manually rescale the channel 1 waveform, and then perform manual
cursor measurements.
8 Set the channel 1 vertical scale to 500 mV/div and the vertical offset to
1.5 V (yellow knobs).
9 Push the Cursors knob; then, turn it to select
the X1 cursor from the popup menu.
10 When the popup menu closes, turn the Cursors
knob to set the X1 timing cursor near one of the
peaks of the channel 1 modulated waveform.
11 Push the Cursors knob; then, turn it to select
the X2 cursor from the popup menu.
12 When the popup menu closes, turn the Cursors knob to set the X2 timing
cursor near the next peak of the channel 1 modulated waveform. The
difference in X cursors shows the time between peaks of the envelope
(X = 220.0 µs).
13 Push the Cursors knob; then, turn it to select the Y1 cursor from the
popup menu.
