To specify bandwidth limiting

1 Press the desired channel key.
2 In the Channel Menu, press the BW Limit softkey to enable or disable
When bandwidth limit is on, the maximum bandwidth for the channel is
approximately 20 MHz. For waveforms with frequencies below this, turning
bandwidth limit on removes unwanted high frequency noise from the
waveform. The bandwidth limit also limits the trigger signal path of any
channel that has BW Limit turned on.

To change the vertical scale knob's coarse/fine adjustment setting

1 Push the channel's vertical scale knob (or press the channel key and
When Fine adjustment is selected, you can change the channel's vertical
sensitivity in smaller increments. The channel sensitivity remains fully
calibrated when Fine is on.
Agilent InfiniiVision 3000 X-Series Oscilloscopes User's Guide
When AC coupling is selected (see
page 63) or excessive voltage is applied to the input, the oscilloscope
automatically switches to 1M Ohm mode to prevent possible damage.
• 1M Ohm — is for use with many passive probes and for
general- purpose measurements. The higher impedance minimizes the
loading effect of the oscilloscope on the device under test.
This impedance matching gives you the most accurate measurements
because reflections are minimized along the signal path.
