Description
Product Overview
The VQP 10HZ-2.7GHZ Frequency Counter is engineered for precision across an extensive frequency spectrum, from the low‑end 10 Hz up to the high‑end 2.7 GHz. Its core architecture combines a high‑resolution 8‑digit LED display with a robust internal timing system that delivers measurement stability of ±3 × 10⁻⁹ s. The device supports both direct counting (up to 10 MHz) and proportional counting (10 MHz‑100 MHz), ensuring accurate results for a broad array of signal types. With selectable gate times of 0.01 s, 0.1 s, and 1 s, users can tailor the measurement window to match specific testing requirements, whether they are evaluating rapid transient events or steady‑state signals. The counter’s input sensitivity reaches 20 mVrms, allowing it to detect weak signals without sacrificing accuracy. Its compact dimensions (10 × 10 × 4.2 in) and lightweight design (4.9 lb) make it portable for field work while still offering the reliability expected in a laboratory environment.
Usage
Designed for versatility, the VQP Frequency Counter excels in both laboratory and on‑site applications. In a lab setting, it can be integrated into signal‑analysis rigs, RF test benches, and component characterization stations, providing engineers with rapid, repeatable measurements for research and development. Field technicians benefit from its rugged construction and low power consumption, enabling long‑duration operation on battery power while performing on‑site diagnostics of communication equipment, radar systems, and industrial control hardware. The intuitive interface, featuring clearly labeled function keys and a bright LED readout, reduces the learning curve for new users and speeds up routine testing. Whether you are calibrating a wireless transmitter, troubleshooting a motor controller, or validating the frequency stability of a crystal oscillator, the counter’s flexible gate timing and dual‑channel capability allow you to capture precise data in real‑time.

FAQ
What is the difference between direct counting and proportional counting?
Direct counting measures each cycle of a signal up to 10 MHz, providing exact counts for low‑frequency signals. Proportional counting estimates frequency for higher ranges (10 MHz‑100 MHz) by measuring the time of a set number of cycles, allowing faster results while maintaining accuracy.
Can the counter be used with battery power?
Yes, the device’s low‑power circuit design enables extended operation on standard AA batteries, making it suitable for field diagnostics where mains power is unavailable.
How does the self‑check function work?
Upon power‑up, the counter runs an internal diagnostic that verifies the LED display, timing oscillator, and input stages. If any component falls outside calibrated limits, an error code is displayed, prompting the user to contact support.
Is the unit compatible with external probes?
The counter includes standard BNC connectors for direct connection to test leads or external RF probes, ensuring flexibility for a variety of measurement setups.
What warranty does VQP provide?
VQP offers a one‑year limited warranty covering manufacturing defects, along with optional extended service plans for added peace of mind.
