Front-Panel Overview
To adjust analog channel vertical scaling and position
To adjust analog channel vertical scaling and position
This exercise guides you through the vertical keys, knobs, and status line.
1 Center the signal on the display using the position knob.
The position knob ( ) moves the signal vertically; the signal is calibrated.
Notice that as you turn the position knob, a voltage value is displayed for a short
time, indicating how far the reference ( )is located from the center of the
screen. Also notice that the ground reference symbol at the left edge of the
display moves with the position knob.
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 vertical sensitivity with the large volts/division knob in the
Vertical (Analog) section of the front panel and notice that it causes the
status line to change.
•Press the 1 key.
If channel 1 was not turned on, a softkey menu appears on the display, and
the channel turns on (the 1 key will be illuminated).
If channel 1 was already turned on, but another menu was being displayed,
the softkeys will now display the channel 1 menu.
When Vernier is turned off, the volts/div knob can change the channel sensitivity
in a 1-2-5 step sequence. When Vernier is selected, you can change the channel
sensitivity in smaller increments with the volts/division knob. The channel
sensitivity remains fully calibrated when Vernier is on. The sensitivity value is
displayed in the status line at the top of the display.
• To turn the channel off, press the channel 1 key until the key is not
illuminated.
Measurement Hints
If the channel is DC coupled, you can quickly measure the DC component of the
signal by simply noting its distance from the ground symbol.
If the channel is AC coupled, the DC component of the signal is removed, allowing
you to use greater sensitivity to display the AC component of the signal.
