Calibrate scope jitter using a Transmission line loop - 09/20/01 EDN-Design Ideas: Digital-clock-period jitter is  variation in  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  oscilloscope jitter from  measured jitter. However, oscilloscopes rarely have a jitter specification, so you must determine  oscilloscope jitter.....(design idea added 1/05)

Delay line upgrades vintage scope - 04/18/02 EDN-Design Ideas: 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 added 1/05)

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.

LED Oscilloscope - George Katz of Balgowlah, Sydney presented a solid state oscilloscope. He says "probably the best advantage is its very small size and the fact that it can run off the power supply of the circuit being tested. Although it has a low frequency range, it can still be used for most circuits. Its poor resolution will still allow for most waveforms to be visualized." ….(electronic schematic added 11/08)

Low Speed AVR Oscilloscope - A few months ago as I was surfing on the net, I saw an oscilloscope based on PIC18F2550 microcontroller and a KS0108 controller based graphical LCD. That was Steven Cholewiak's web site. I had never seen before so amazing microcontroller, only oscilloscope. That was realy impressive circuit, so I decided to design something like that but in C language instead ….(electronic schematic added 11/08)
