4 Channel Oscilloscope Adapter -   will introduce the adapter to see the wavefrom of four kinds of the signals at the same time with the oscilloscope on these pages. At the classy oscilloscope, it is equipped...(circuit / schematic design added 07/08/09)
A Decimal to BCD Decoder -  This circuit will take the input from a keypad with up to 16 buttons, and convert it into a ''latched'' BCD output….. [Circuit Designed by Andy Collison]
Active-filter circuit and oscilloscope inspect a Class D amplifier's output -  1-Dec-06 Issue of EDN  Ease debugging of bridge-output pulse-width-modulated audio amplifiers with this circuit.... [Design Idea by John Guy, Maxim Integrated Products Inc, Sunnyvale, CA; Edited by Brad Thompson and Fran Granville]
Aliasing aids Signal analysis -  09/15/94 EDN-Design Ideas....Common wisdom decrees that digital-oscilloscope users must always guard against aliasing by choosing a sampling rate that is several times  highest frequency component....FIGURE ONLY.... EDN is migrating links. This link is not verified.  Google the "title" EDN for new link.

AVR based oscilloscope -  A mega32 based low speed oscilloscope. It can be used to measure signals up to 5 kHz. The input voltage range can be up to 24V AC or 30V DC.….(Circuit design added 03/09)

Calibrate scope jitter using a transmission line loop -  20-Sep-01 Issue of EDN  Digital-clock-period jitter is the variation in the period of a clock cycle compared with a nominal (average of many cycles] clock period. To accurately measure period jitter using an oscilloscope, you must subtract the oscilloscope jitter from the measured jitter. However, oscilloscopes rarely have a jitter specification, so you must determine the oscilloscope jitter.... [Design Idea by David Cuthbert, Micron Technology, Boise, ID]
Debugging a PC I Bus with a Mixed-Signal Oscilloscope 5988-7745EN -  Aligent Application Note  (app note added 6/07)
Debugging with Combined Oscilloscope & Logic Analyzer Measurements -  Agilent Application Note....[App Note]
Decimal to BCD Convertor -  This circuit will provide an output in Binary Coded Decimal from any of the input switches. The input switches may be expanded to 16 switches, providing a Hexadecimal to BCD conversion.
.… [Ron J.]
Delay line upgrades vintage scope -  18-Apr-02 Issue of EDN  Vintage triggered-sweep oscilloscopes find use in many applications. However, they have no internal delay line, so they can't display the pulse that triggers the sweep. Moreover, early laboratory scopes contain delay lines having insufficient delay to display such pulses during a uniform portion of the sweep.... [Design Idea by Robert Houtman, Blaine, WA]
Delay Simulator Debugs Communications Equipment -  10/27/94 EDN-Design Ideas.... Phone calls over satellite circuits experience a ¼-sec transmission delay in each direction. The low-cost circuit (around $20]in Fig 1a simulates this delay and provides hooks for inserting noise, echo, and other impairments. Designers debugging modems, fax machines, and other communication equipment can use this circuit to troubleshoot.... EDN is migrating links. This link is not verified.  Search the "title" EDN for new link.
DSO-triggering scheme is cheap and efficient -  05/07/98 EDN-Design Ideas....Although a logic analyzer is useful in troubleshooting a new design, nothing beats a digital storage oscilloscope (DSO) for the ability to see bus levels and timing. However, the trigger mechanisms on most DSOs are not  sophisticated enough to trigger on a specificm P bus state....NOTE  Page includes several designs, scroll to find this one.... [Design Idea by Robert Perrin, Z-World, Davis, CA]
Finding Hidden Problems using Agilent�s Deep-Memory Oscilloscope: How IBM Solved a Mystery EPSG090979 -  Aligent Application Note  (app note added 04/05/06)
Four Channel Oscilloscope Adapter -   will introduce the adapter to see the wavefrom of four kinds of the signals at the same time with the oscilloscope on these pages. At the classy oscilloscope, it is equipped with the function to see more than one signal at the same time. The one which I am having can see only the one signal. Therefore, I made the adapter to see four kinds of the signals at the same time....(circuit / schematic design added 07/08/09)
Jitter Analysis Techniques using an Agilent Infiniium Oscilloscope 5988-6109EN -  Aligent Application Note  (app note added 6/07)
