6. [Math] Key The [Math] key provides access to add, subtract, multiply, differentiate,
integrate, FFT (Fast Fourier Transform) and square root functions. See “Measurements
and Math Functions” on page 191.
7. [Label] Key Press this key to access the Label Menu, which lets you enter labels to
identify each trace on the oscilloscope display. See “Using Labels” on page 183.
8. Vertical Position Control Use this knob to change the channel’s vertical position on
the display. There is one Vertical Position control for each channel. See “Using the
Analog Channels” on page 59.
9. Channel On/Off Key Use this key to switch the channel on or off, or to access the
channel’s menu in the softkeys. There is one Channel On/Off key for each channel. See
“Using the Analog Channels” on page 59.
10. Vertical Sensitivity There is one knob marked for each channel. Use these
knobs to change the vertical sensitivity (gain) of each channel. See “Using the Analog
Channels” on page 59.
11. Waveform Keys The [Acquire] key lets you set the oscilloscope to acquire in
Normal, Peak Detect, Averaging, or High Resolution modes (see “Acquisition Modes” on
page 265), and lets you turn Realtime sampling off or on (see page 269). The [Display]
key lets you access the menu where you can select infinite persistence (see page 182),
switch vectors on or off (see page 187), and adjust the display grid (graticule) intensity
(see page 181).
12. Intensity Control Rotate clockwise to increase analog waveform intensity;
counterclockwise to decrease. You can vary the intensity control to bring out signal detail,
much like an analog oscilloscope. Digital channel waveform intensity is not adjustable.
More details about using the Intensity control to view signal detail are on page 180.
13. Digital Channel Controls These controls switch the digital channels on and off,
and can be used to select a digital channel for repositioning on the display.
Press the [D15-D0] key to turn on the digital channels (the [D15-D0] key will illuminate).
There are two indicators above the Digital Channel Control Knob: Select and Pos
(Position). When Select is illuminated, rotate the knob to select a digital trace. The
selected trace will change from blue to red. Push the Digital Channel Control Knob to
toggle from Select to Pos. Rotate the knob and press it again to re-position the digital
trace.
