20 GSa/s Sample Rate on All Channels at Once!
• The full real-time bandwidth of
up to 6 GHz is supported on
every channel by the 20 GSa/s
sample rate.
• This industry-leading sample
rate produces more accurate
and repeatable measurements,
avoiding measurement error
and signal aliasing due to under
sampling, as shown above.
• The combination of 6 GHz
bandwidth and 20 GSa/s
sample rate on all channels
makes the 54850 series ideal
for designs that include:
PCI-Express, Serial ATA,
Rapid IO, HyperTransport,
InfiniBand, or Gigabit Ethernet.
20 GSa/s provides accurate measurement. 10 GSa/s is not enough.
5 GSa/s is not enough.
Sample rate Measured rise time
20 GSa/s 89 psec
10 GSa/s 137 psec
5 GSa/s 238 psec
Example for 90 ps rise time input
