I need to figure out if I am generating a 140hz signal with an antique of a scope. Scope does not have any fancy setting like time. It is a navy relic. How do I go about measuring the frequency? I have a signal showing 3 cycles with 100hz sweep. Do I need a better scope?
Better is easier, but not absolutely necessary. How do you know it's a 100Hz sweep? But the completely uncalibrated sweeps are difficult to use for frequency. Usually the sweep speeds are in steps, X seconds/division, and you just count the number of divisions and multiply/divide. They're not uncalibrated. But if it's an unmarked knob you'd only normally use that for waveform quality.
140 Hz is very close to C#3 on a piano. Compare it by ear? Feed signal to a tuner? (Cheap frequency counter.) My Fluke DMM does Hz on AC. -- Jim _______________________________________ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
