How Does It Compare with Other JLab Frequency Counters?
| Model | Frequency coverage | Other details |
|---|---|---|
| This counter (EL-DSO-10298) | 0.01 Hz to 2.4 GHz over two channels | 8-digit LED display; adjustable range and gate time; x1/x20 attenuator on CH B |
| 1000MHz Frequency Counter | 0.1 Hz to 1000 MHz | Backlit LCD; microcontroller based; gate times of 1 s and 10 s; range selection in three steps |
| Frequency Counter | 1 GHz | Microprocessor based; frequency measurement, pulse counting and crystal measurement |
Pick this counter when you need readings above 1 GHz. The 1000MHz model covers signals up to 1000 MHz on a backlit LCD, and the 1 GHz Frequency Counter offers pulse counting and crystal measurement alongside frequency measurement.
What Is the 2.4 GHz Frequency Counter Used For?
A frequency counter counts the cycles of an input signal over a precisely timed gate interval and displays the result as a frequency, which makes it far more precise than reading frequency from an oscilloscope screen or a generator dial. With one input for RF and one for low and medium frequencies, this counter serves communication engineering, B.Sc. physics and electronics, polytechnic and ITI labs, as well as radio service benches: setting an oscillator or RF signal generator to a target frequency, checking crystal oscillator and clock frequencies in digital circuits, measuring the output of VHF and UHF transmitter stages, and timing slow signals on the DC-coupled channel.
What to Specify When Ordering
- Quantity — the number of counters for your benches.
- Signal sources to test — function or RF signal generators from the list below are separate items that can be quoted on the same enquiry.
- Tender and shipping details — any tender reference and the packing or labelling the consignment needs.
Frequently Asked Questions
Which input should I use?
CH A for signals from 50 MHz to 2.4 GHz — a 50-ohm, AC-coupled input that should not see more than 3 V. CH B for 0.01 Hz to 50 MHz — a 1 MOhm input with a x1 or x20 attenuator, DC coupled below 100 Hz and AC coupled above, rated for up to 30 V DC/AC peak.
How does the gate time affect the reading?
The gate time is how long the counter counts before it shows a result. A longer gate collects more cycles, so the display resolves the frequency to more digits but updates less often; a shorter gate gives quicker readings with less resolution.
What do the time base stability figures mean?
Every reading is referenced to the counter’s internal time base, so its stability sets how far a result can wander. Stability of ±3 x 10−9 per second and ±2 x 10−8 per month means the reference drifts by no more than about two parts in a hundred million over a month.
What comes in the box?
A power cable, two BNC-to-crocodile-clip probes and an instruction manual are supplied as standard accessories.
How does it differ from the 1000MHz Frequency Counter?
The 1000MHz Frequency Counter measures from 0.1 Hz to 1000 MHz and shows results on a backlit LCD. This counter extends to 2.4 GHz through its separate RF channel and uses an 8-digit LED display.
What should an export enquiry include?
The number of counters, the destination country and the port or city of delivery, your preferred delivery terms (for example FOB or CIF), any packing or labelling instructions and, for a tender, its reference.
Who manufactures this frequency counter?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, manufactures it at its works in Ambala, Haryana, India, and quotes as the maker.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a manufacturer of electronics test instruments, trainers and laboratory equipment in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. This counter is produced at JLab’s own works, not sourced through a trader, so universities, polytechnics, dealers and importers order directly from the maker and return to it for repeat supplies. JLab exports worldwide and ships to buyers in every region — for example Chad in Central Africa, Chile in South America, Libya in North Africa, Romania in Eastern Europe and Slovenia in Southern Europe. Tender information is on the JLab lab tenders page.
