Buying Guide: What to Consider When Choosing Frequency Counter

Whether you’re looking for a traditional unit or the best frequency counter for ham radio, there’s a set of features to keep in mind before purchasing any counter. Want to know what those features are? Let’s find out!

a) Type

Besides the traditional frequency counter, other handheld alternatives may be more suitable for your purposes. Despite being smaller, the handheld models can be more convenient due to how easy it’s to carry around and operate them.

Naturally, a handheld device may not be as powerful as the classic frequency counter. That’s why you must figure out which one fits your demands the most.

b) Frequency Range

Due to the many counters available, the frequency range offered varies a lot. Ultimately, it’s up to you to decide which unit has the power needed to fit the task at hand. In here, you’ll find frequency counters with up to 2.4GHz, though it depends on the brand and its products.

c) Ease of Use

Frequency counters aren’t necessarily hard to use, but knowing how each model operates could get tricky if there aren’t proper instructions included.

If that’s the case, make sure to pick a model with an easy-to-understand front panel, attenuators, and knobs. Some of the picks in our frequency counter review article lack detailed instructions, but their interfaces remain easy to figure out.

d) Screen

As seen during our reviews, the screen of a frequency counter varies a lot. Here, you want to consider the number of digits displayed, as well as how easy it is to read the frequencies. A backlit background is also a convenient feature that would come in handy under specific circumstances.

 

e) Functions

While searching for frequency counters, you’ll find that your preferred unit may be capable of doing far more than that. A clear example of that is the HUABAN devices, which work as both frequency counters and crystal oscillator testers.

Other units may offer voltage readings, and so on. With a device that offers all of those functions and more, you’ll have all the tools needed to make many types of measurements.

f) Assembly Kits

Last but not least, consider whether or not you want an assembled frequency counter or the kit to build one. Does that sound odd? Well, HUABAN offers different kits with all the pieces to assemble your frequency counter, so the possibility is there.

Why buy a kit instead of an already assembled unit? I hear you ask. In many cases, putting all the parts together is a task that most DIYers prefer to do. They get to test how the counter works better and what can and can’t the counters do, among other things.

Besides HUABAN, Arduino is another brand that offers kits for assembly. Although limited, the best Arduino frequency counter can still put up a good performance.

Frequently Asked Questions: About Frequency Counter

a. What is a frequency counter used for?

Defined as an electronic instrument, the frequency counter is calibrating to measure frequencies via the number of oscillation cycles or pulses per second during a periodic electronic signal.

b. How do frequency counters work?

A frequency counter uses a counter to accumulate the number of events that occur during a specific time-lapse. Once the gate time finishes, the value caught by the counter gets displayed on the screen, and the counter resets back to zero.

c. How to use a frequency counter?

Frequency counter is using a pretty simple process. Regularly, you only have to turn on the counter and apply a signal to the instrument’s input. Besides measuring digital logic signals, the best RF frequency counter can measure radio frequencies and microwaves.

d. Is the frequency counter accurate?

A frequency counter owes its accuracy to its time base stability, which may vary due to interference, sudden movement, or other events. So, while the instrument can be accurate most of the time, some circumstances may keep it from being as precise as it can be.

e. Is the handheld frequency counter any good?

While many would dismiss handheld models because they’re not as powerful, the truth is that this type of counters can be the right choice. They’re portable, easy to use, and affordable – three aspects that make the handheld frequency counters a convenient pick. Connect a frequency counter to a radio is very carefully.

Final Words
