•
Toggle each softkey and notice which keys cause the status line to change.
Channels 1 and 2 have a vernier softkey that allows the Volts/Div
knob to change the vertical step size in smaller increments. These
smaller increments are calibrated, which result in accurate
measurements, even with the vernier turned on.
•
To turn the channel off, either press
1
(for HP 54645A) or
A1
(for HP 54645D) a second time or press the left-most softkey.
Invert Operating Hint
Inversion affects how a channel is displayed, but it does not affect triggering.
The trigger does not see the inversion, and thus is not affected. If the trigger is
set to a rising edge, it remains rising after inversion.
Bandwidth Limit
The displayed bandwidth limit of the selected channel is 20 MHz, and is
available for channels 1 and 2.
