2 Change the vertical setup and notice that each change affects
the status line differently.
You can quickly determine the vertical setup from the status line in the
display.
• Change the venical sensitivity with the VoltstDiv knob and notice
that it causes the status line to change. For channels 3 and 4 on the
HP 54601A, press QJ or [JJ. Then use the softkeys to change
the vertical sensitivity.
• Press [I].
A softkey menu appears on the display, and the channel turns on
(or remains on if it was already turned on).
• Toggle each of the softkeys and notice which keys cause the status
line to change.
Channels
1 and 2 have a vernier softkey that allows the Volt/Div
knob to change the vertical step size in smaller increments.
These smaller increments are ealibrated, which results in accurate
measurements even with the vernier turned on.
• To turn the channel off, either press [I] a second time or press
the left-most softkey.

When you are triggered on the signal you are inverting, the inversion also applies to
the trigger signal (what was a rising edge now Is a falling edge). If the signal has a
50% duty cycle (square wave or sin wave) the displayed waveform appears not to
invert. However, for signals with a duty cycle other that 50%, the displayed
waveform does invert as you would exPect
