Nowhere does this factor arise extra frequently than with frequency counters. such a lot counters have plenty of digits, implying excessive precision. Accuracy is one other subject. The count number you get will depend on how lengthy the gate remains open. that's managed by way of a frequency reference, that is an inner oscillator managed by way of a quartz crystal. In a really genuine feel, the counter is evaluating the incoming signal’s frequency to that of the instrument’s crystal, so version within the crystal oscillator’s frequency will skew the count number. Crystals are utilized in many oscillator purposes requiring low waft, yet they do wander a piece with temperature and age. such a lot counters have inner trimmer capacitors to fine-tune the crystal’s frequency, yet environment them calls for both one other, relied on counter for comparability; an oscillator whose frequency is depended on; or a few cleverness with a shortwave radio which may obtain WWV, the nationwide Bureau of criteria atomic clock’s time sign originating from castle Collins, Colorado. That station declares its provider at a hugely specific, exact frequency, and it's attainable to check it audibly for your counter’s oscillator, utilizing the radio as a detector. once they zero-beat, or combine with no producing a distinction tone, your counter is spot on frequency. played very rigorously with a counter that’s been totally warmed up, zerobeating opposed to WWV can get you inside of 1 Hz, that is darned sturdy. On many counters, the gate time could be chosen with a change. Longer gate instances offer you extra digits to the precise of the decimal aspect, yet their accuracy is simply nearly as good because the counter’s reference oscillator. Don’t take them extraordinarily heavily except you're definite the reference is right adequate to justify them. in case your right-most digit specifies 1 Hz however the reference is 20 Hz off, what does that digit suggest? For audio frequencies, you’ll desire a relatively lengthy gate time to get sufficient cycles to count number. For radio frequencies, a swifter gate time is extra applicable. Connecting a counter to the circuit less than try could be tough at times. Loading of the circuit’s resource of sign iteration is a true challenge, pulling it off-frequency and affecting the count number considerably. specifically in the event you contact your probe at once bankruptcy 6 operating Your guns: utilizing try apparatus 109 to 1 lead of a crystal in a crystal oscillator, the capacitance of the probe and counter can shift the oscillator’s frequency via a shocking volume. To probe this kind of beast, search for a buffer among the oscillator and every little thing else, and take your size from its output. because the circuit itself additionally might load the oscillator, it’s hugely most probably buffer is there somewhere. nowadays, such a lot crystal oscillators are shaped with IC chips, instead of transistors, with the buffer being at the chip and the frequency output coming from a pin now not attached to the crystal. Use your scope to discover it after which attach the counter to that pin. Analog Meter utilizing an analog VOM or FET-VOM calls for studying the location of a meter needle, instead of simply analyzing a few numbers off a reveal.
