Acquisition
3. Click Digital Filters (DSP) Enabled to
turn the enhanced bandwidth on. You
must set the sample rate correctly to
enable DSP.
4. To force a constant sample rate that
enables DSP filters, check Force
Constant Sample Rate.
NOTE. If not already set, selecting Constant
Sample rate sets the horizontal mode to
constant sample rate, sets the sample rate
to allow DSP, and selects a DSP bandwidth.
5. Select the desired bandwidth from the
Bandwidth list.
The available bandwidth selections
depend on your instrument, probe, and
probe tip.
Selecting Analog Only selects a
hardware (HW) bandwidth.
6. To apply your selections to all channels,
check Apply To All Channels.
When different probing makes it
impossible for the instrument to set all
channels the same, the instrument sets
each channel to the closest bandwidth
value possible.
The bandwidth indicator appears in the
vertical readout when the enhanced
bandwidth is turned on.
Quick Tips
Right click the waveform handle to display a menu where you can select the channel bandwidth and other bandwidth
enhanced settings.
The DSP enhanced bandwidth occurs at maximum sample rate.
Use the DSP enhanced bandwidth when your signals have rise times less than 50 ps.
Select Analog Only for higher waveform throughput, overdriven signals, and when you prefer to use your own DSP
post-processing.
You can limit the instrument bandwidth by selecting Vertical > Bandwidth Limit and then selecting the bandwidth.
