HP 54540A 4 Channel, 500 MSa/s Monochrome Digitizing Oscilloscope

The Performance You Need... The Features You Want.

These state of the art 500 MHz realtime oscilloscopes have the extra performance and features that you need to get an accurate view of the high frequency signals you encounter, whether you do analog or digital design, R&D or manufacturing test. With 32 K memory per channel, 4 channels, sample rate up to 2 GSa/s, 1 ns peak detect, and sophisticated triggering, you can be confident that you won't miss critical signal activity. These feature rich digitizing scopes also include standard FFT, floppy disk drive, and sequential single shot acquisition for better analysis and characterization of your signals. Choose between a color flat-panel display (54540C) or monochrome display (54540A).

Optional Capabilities

Optional Telecommunication-Mask Application

Make telecom mask-template measurements to ANSI, CCITT, and ISDN 
standards using the HP 54520 or 54540 series oscilloscopes equipped 
with Option 001.  Option 001 features 21 standard masks stored on a 
flexible disk.  You can automatically trigger on positive isolated 
ones in live traffic for many standard telecom signals.  The scope 
will automatically best-fit the test signal to many masks and give 
automatic pass-fail comparisons of the mask to its corresponding 
input signal.

For more information on Option 001, Telecommunications Masks 
Applications ask your HP Sales representative for HP Product Overview 
5963-1859E (international version) or 5963-1859 EUS (US version).

Optional Active Probing

The HP 1144A active probe features 800-MHz bandwidth, 2-pF input 
capacitance, and 1-Mohm input resistance.  The HP 1145A two-channel 
active probe features 750-MHz bandwidth, 2-pF input capacitace, and 
1 Mohm input resistance and is designed for easy connection to 
surface mount devices.
