Op Amp Spot Noise Measurement Test Circuit

This is where we talk about testing, measuring and repairing things. Sometimes we have to repair the equipment we use to test, measure and repair other things. It's an endless cycle of fixing the broken things we need to fix other broken things.

Op Amp Spot Noise Measurement Test Circuit

"Op Amp Spot Noise Measurement Test Circuit," Raytheon Linear Integrated Circuits, 1989.

While spring cleaning and throwing out data books I scanned the Raytheon catalog to see if anything caught my eye.
This circuit, an RC4136 application, measures op amp spot noise at 1 Hz, 10 Hz, 100 Hz and 1 kHz as well as DC to 1 Hz "wideband."
While there are certainly more modern op amps than the 4136 that can be used, its still appears to be a very useful circuit.

SOCIAL MEDIA PLATFORMS should advance FREEDOM OF SPEECH. Yet too many Americans have seen their accounts suspended, banned, or fraudulently reported for unclear “violations” of user policies. No matter your views, if you suspect political bias caused such an action to be taken against you, share your story with President Trump.
