Hi Everyone,
This month my Technical Tidbit is written by Tim Maloney of Intel for
publication on my site. He has devised a very good transmission line
equivalent circuit than makes it easy to understand transmission line
impedance behavior as a function of line length and termination
impedan
It's hard to imagine needing more that 100mW at that frequency for short
range (say <30m)

stability problem after 20+ years of use and several over-power incidents
caused by several individuals including myself. Turns out that the carbon

Hello
Does anyone out there [if any equipment reps on list] have an OPHIR 5127F
amplifier for 12 month lease or rental?
We used a similar one for years and suited our immunity test setup very well.
Calibration fields were easily repeated prior to testing. Very stable amp.
The one we have now s

I used the ancient HP-85869PC data acquisition software, and HP (being

this to extend the HP-8566B’s capabilities to commercial EMI testing. (For
