Tektronix FCA3020 Frequency Counter and Timer, 20 GHz, 100 ps Resolution

Description

When a product fails because a clock wanders, you need a number you can trust. The Tektronix FCA3020 frequency counter gives you that number for signals up to 20 GHz. It also times single events down to 100 ps. Lost in HCM lists it for rental and sale, and it arranges service on request.

What the FCA3020 measures

The Tektronix FCA3020 frequency counter counts frequency and period, and it measures the time between two events. In addition, it reports phase between two signals. Engineers use it to check oscillators, pulse timing and frequency stability. A maintenance team can also use it to confirm that a repaired board still runs on frequency.

Key figures

Watching drift instead of one reading

A single number hides a lot. Because the counter plots results over time, you can see a clock settle after power-up. The histogram shows how widely repeated readings spread. As a result, you spot jitter and slow drift without exporting data first.

Resolution is not accuracy

Twelve digits per second describes how finely the counter reads, not how close it is to the true value. Real accuracy comes from the timebase, a clean signal, sensible trigger settings and the measurement interval. So decide how good your reference must be before you order. If the job needs a tighter reference, ask about the oven timebase option and your calibration needs.

Connecting the Tektronix FCA3020 frequency counter

Feed the signal into input A, and add a second timing signal on input B for interval work. Then pick the input that suits your frequency, because microwave signals use the high-frequency input where it is fitted. Check voltage limits, termination and grounding first. Never connect a counter input to mains power. Meanwhile, USB or GPIB lets a computer log the results during longer runs.

Ordering through Lost in HCM

Lost in HCM holds the equipment, while SMK Vietnam only shows the listing. To rent or buy the Tektronix FCA3020 frequency counter, request a quote from Lost in HCM and describe your signal. Include the frequency, the signal level, any options and where it must go. You can also browse the frequency counter listings, read the maker’s pages at Tektronix or contact SMK Vietnam for help.

FCA3020 questions

Can it compare the phase of two signals?

Yes. The counter lists a phase resolution of 0.001 degree, and you connect the two signals to inputs A and B.

How do I control it from a computer?

It offers USB and GPIB interfaces, so a test script can read results and log them.

Does the photo show this exact model?

No. The picture is a reference image of the FCA3000 and FCA3100 series, so confirm options and accessories with Lost in HCM.
