Appendix E High Resolution Digitizing With the 3458A 349
Appendix E High Resolution Digitizing
With the 3458A
(From Product Note 3458A-2)
Introduction
In your system or stand-alone with your computer, the 3458A can digitize wave
forms with low distortion and very high resolution. The 3458A has the
measurement speed and precise timing necessary for direct sampling of signals
with frequency components up to 50 kHz or, with repetitive signals, subsampling
up to 12 MHz with
16 bits of resolution and more.
In this product note you will learn how to:
1. Configure the 3458A to capture transient signals using direct sampling.
2. Configure the 3458A to capture repetitive signals using sequential
sampling.
3. Use slope and level triggering to capture the data where you want.
4. Transfer measured signal data from the 3458A to your HP 9000 Series
200/300 Computer at 100 kSamples/s.
5. Use the 3458A's Program Memory to capture signals on multiple channels,
store them in the 3458A's Reading Memory, interrupt the HP 9000 Series
200/300 Computer when the task is complete, and transfer the data from
the multimeter to the computer for comparison, analysis, and graphic
presentation.
6. Use the 3458A Option 005 Wave Form Analysis Library, to acquire,
analyze, and present the digitized signals.
7. Interpret specifications that pertain to wave form digitizing and dynamic
performance.
Speed with Resolution
• 16 bits @ 100 kSamples/s
• 18 bits @ 50 kSamples/s
The 3458A offers you complete flexibility for speed and resolution over the audio
frequency bandwidth. The DCV measurement path can digitize your audio
frequency signal with less than 175 ns trigger latency and less than 100 ps
