- Commodity name: Handheld Mobile Transport Clock DNHH-9-GB
The DNTS-9 series of high-performance time servers provides stable, reliable, and traceable network time services for closed‑environment data centers.

Product Features
When paired with the newly developed DNTS‑9 series high‑performance time servers, it can provide stable, reliable, and traceable network time services for closed‑type data centers. In enclosed server room environments where satellite receiving antennas cannot be installed, operations personnel can periodically use the DNHH‑9‑GB portable clock to receive satellite time signals from outdoors, then bring the DNHH‑9‑GB into the data center. By connecting the DNHH‑9‑GB to the DNTS‑9 via a dedicated interface and cable, the DNTS‑9 obtains precise time information traceable to the UTC time source, thereby continuing to deliver stable and reliable time services to the internal network of the data center.
It provides a precise and reliable time‑frequency reference for scientific expeditions, exploration, surveying, and mapping activities. The DNHH‑9‑GB handheld portable clock can operate continuously for more than 14 hours without an external power supply and can perform real-time frequency calibration via GNSS satellite systems, delivering accurate and dependable time‑frequency information to scientific and engineering instruments under a wide range of demanding environmental conditions.
Product Overview

Dimensions: 340 mm × 276 mm × 77 mm

The DNHH-9-GB handheld time‑keeping clock is a portable, high‑precision time and frequency reference source. Unlike rack‑mount units, the DNHH-9-GB features a compact size, lightweight design, and an integrated power supply, making it suitable for mobile applications such as outdoor use.

The DNHH-9-GB features a high‑performance oven‑controlled crystal oscillator and can lock its frequency to the UTC atomic clock ensemble maintained by the U.S. Naval Observatory and the China National Time Service Center via the GPS/BDS satellite systems. When satellite signals are lost, the device automatically compensates for frequency drift in the built‑in oven‑controlled crystal oscillator using an advanced discipline algorithm. Consequently, the DNHH-9-GB can serve as a portable time source, enabling the transfer of satellite‑derived time signals to locations where installing a satellite antenna is impractical.

The DNHH-9-GB handheld time‑keeping device automatically calibrates by receiving GPS/BeiDou satellite signals, eliminating the need for manual intervention and obviating the requirement for additional specialized equipment or verification.

The DNHH-9-GB features a high-capacity built-in lithium‑ion battery pack (139 Wh), providing continuous operation for at least 14 hours on a full charge (typical value when equipped with a CPT temperature‑compensated crystal oscillator). The longer the device maintains continuous satellite signal lock, the higher the stability of its internal frequency reference, resulting in a more precise clock signal for downstream equipment. The battery pack utilizes brand‑new, original Panasonic cells and is paired with a mature battery management system to ensure safe operation and storage.

The panel is equipped with an OLED/VFD display that provides clear visibility of the device’s operating status and remaining battery level even in direct sunlight. It also features six high-brightness, dual-color LED indicators that intuitively signal operational status, alarm conditions, and other states.

The rear panel of the device is equipped with a variety of commonly used output interfaces, providing standard time and frequency signals such as a 1‑PPS pulse, a 10‑MHz clock signal, ToD time information, and an IRIG‑B code signal, thereby supplying timing signals to a wide range of equipment. Depending on the specific application scenario, NTP network interfaces, PTP network interfaces, and arbitrary‑frequency output interfaces can be optionally configured or custom‑designed to meet the diverse requirements of various industries and use cases.
