[R-390] Measuring tangential sensitivity

[Bill Hawkins]

Roy,

Seems like I was off the mark. As is usual, one should do some
research before hitting the keyboard, unless one's intent is to
liven things up a bit.

>From a blurb for Agilent wide range laboratory detectors:

"Tangential sensitivity is the lowest input signal power level
for which the detector will have an 8 dB signal-to-noise ratio
at the output of a test video amplifier. Test amplifier gain
is not relevant because it applies to both signal and noise.
Agilent detectors are designed for optimal flatness and SWR."

Since R-390s do not contain video detectors, I let the matter drop.

Regards,
Bill Hawkins
