    Signal Generator Level/Output

    Greetings everyone! I did a search and couldn’t find an answer to what may be a silly question. I have the attached signal generator and using an oscilloscope to test the outputs of a solid state receiver to measure where it starts to clip. On the signal generator, how far up do I need the...

    $20 Fm alignment tool idea

    So why can’t I pickup up one of those cheap fm modulators that are used to connect to a car radio with built in Bluetooth and play a tone through my phone to the tuner and adjust the cans for maximum output? Seems a lot cheaper than a $400 (at least) fm alignment generator.

    Sanity check on connecting signal generator to receiver aux-in

    I'm troubleshooting a Kenwood KR-5600 (see also: this thread) where I recapped and replaced some transistors on the power amp board. Now I have very weak audio at the left speaker but seemingly good audio volume in the right channel. To troubleshoot, I first traced the signal in the working...

    Simpson Model 479 TV-FM Signal Generator

    Function Generator Output Distortion - Need Advice

    I picked up a cheap VIZ WR-550B function generator so i can learn to use one properly. I hooked it up to my scope and noticed some distortion on the output that I would like to eliminate if possible. My primary concern is the distorted shape of the sine wave and the two ripples at 1 MHz -...

    EICO 377 signal gen restoration

    I'm still new-ish to working on gear and learn more with each piece that I work on. As such, I've picked up pieces of classic-era test gear with the intent of gaining knowledge through restoration. I paid $20 at an estate for a box full of an Eico 377 Audio Gen, a model 232 VTVM, and a model...

    Heathkit IG-5218 sine-square wave audio signal generator issues

    I bought a Heathkit IG-5218 sine-square wave audio signal generator on eBay. When I opened it up, a number of wires were clipped. Found the assembly manual for an IG-18 and reconnected wires and fired it up. After calibrating it it’s putting out a beautiful sine wave, but it’s having issues...
