HD Mode
The HDO9000 with HD1024 high definition technology offers more quantitization levels and greater precision when digitizing waveforms. HD1024 allows for
dynamic ADC configuration based on the number of active channels and applies bandwidth filtering when the sample rate is reduced below 10 GS/s to prevent
aliasing and increase resolution. When HD1024 is off, the oscilloscope operates in continuous 8-bit resolution.
HD Summary
dialog shows per channel:
•
Bandwidth due to combined manual
bandwidth filters, anti-aliasing filters,
and coupling setting
•
Bits resolution for which the ADC
Configuration is optimized due to the
Active Channels selection
•
Bits resolution gained due to all the
Optimized Filtering of bandwidth
•
Total Resolution (the sum of ADC
Configuration and Optimized Filtering)
When HD Mode is On, Active Channels
shows the
ADC configuration options
:
9-bit, 10-bit, or Maximize based on actual
active channels. (When HD Mode is Off,
it shows maximum sample rate per
channel.)
