The HP 54520 and 54540 Series
Oscilloscopes
This family of digitizing oscilloscopes provides a choice of channel count and sample
rate. The HP 54522A and 54542A have two and four channels respectively and offer
500 MHz repetitive and real-time bandwidth and a 2 GSa/s sample rate. The
HP 54520A and 54540A also have two and four channels respectively and offer
500 MHz repetitive bandwidth, but offer a lower maximum sample rate so less
real-time bandwidth.
