Power Meters & Power Sensors

Ceyear has introduced the new 2439D RF Power Meter, together with an updated lineup of USB and LAN power sensors for precise RF, microwave and millimetre-wave power measurements.

Accurate power measurement is one of the key requirements in RF and microwave engineering. Whether used in R&D laboratories, production testing, field service or system integration, a reliable RF power measurement platform is essential for verifying signal performance, device output levels and test system stability.

The new Ceyear 2439D Microwave Power Meter is designed as a flexible measurement platform for average and peak power testing. When combined with compatible Ceyear USB power sensors, it enables engineers to perform precise measurements across a wide range of RF and microwave applications.

Measurement Solutions for European RF and Microwave Applications

Ceyear’s power measurement portfolio includes microwave power meters, USB power sensors and LAN power sensors, covering applications from DC up to 110 GHz. This broad product range allows laboratories, manufacturers and service teams in Europe to select the right configuration for their specific measurement environment.

The system supports measurement of key RF power parameters, including:

• Average power
• Peak power
• Peak-to-average power ratio, PAPR
• Pulse width
• Rise time
• Pulse period

Depending on the selected sensor, the solution offers a maximum average power dynamic range of up to 96 dB, a peak power dynamic range of up to 55 dB, coaxial frequency coverage up to 110 GHz, rise time down to ≤13 ns, and minimum measurable pulse width of 50 ns.

2439D RF Power Meter — Flexible Multi-Channel Platform

The 2439D RF Power Meter can be used with Ceyear USB power sensors from the 87233, 87235, 87236 and 87237 series. These sensors support average and peak power measurements and can be connected directly to the 2439D platform or used with PCs, laptops and compatible Ceyear measurement instruments.

For engineers working with multi-channel RF systems, the 2439D supports the simultaneous connection of up to four power sensors, enabling efficient comparison and monitoring of several measurement points at the same time.

Measurement results can be displayed as numerical values or waveforms, while operation is simplified through a combination of front-panel keys and a touchscreen interface.

For European laboratories, manufacturers and field engineers looking for a flexible RF power measurement solution, the Ceyear 2439D offers a compact and capable platform for modern microwave testing environments.

Compatible High-Accuracy Power Sensors

The Ceyear 2439D Microwave Power Meter supports plug-and-measure operation with a wide range of high-accuracy USB power sensors. Depending on the selected sensor series, the system can be used for CW, average, peak, pulse, time-gated and statistical power measurements.

The 2439D Microwave Power Meter is compatible with the following Ceyear power sensor series:

• 87233 USB CW Power Sensors
• 87235 USB Average Power Sensors
• 87236 USB Peak/Average Power Sensors
• 87237 USB Thermocouple Power Sensors

Each power sensor is factory-compensated, with compensation data stored internally. This enables convenient plug-and-measure operation, reduces preparation time before testing and helps ensure long-term measurement stability.

Rich Interface Configuration

The front panel of the 2439D provides two sensor channel interfaces, labelled A and B. The USB port in the lower-right corner can be shared with the rear-panel channel C. However, only one sensor can be connected to the lower-right USB port and rear-panel channel C at the same time.

The rear panel provides two additional channel interfaces, C and D. The USB port can also be shared with channel D, but only one sensor can be connected to the USB port and channel D simultaneously.

Multiple Measurement Modes

The 2439D Microwave Power Meter supports multiple measurement modes for different RF and microwave testing scenarios.

Averaging Mode
This mode enables precise average power measurements for continuous wave signals and various modulated signals, including common wireless communication formats such as 5G, LTE, Wi-Fi and WLAN.

Trace Mode
Trace mode displays envelope power over time, presenting results as both waveforms and numerical values. It supports the simultaneous measurement of up to 16 pulse parameters, with up to eight parameters displayed on the instrument panel at the same time.

Time-Gated Mode
This mode measures average power, peak power, peak-to-average ratio and minimum power within up to four independent time gates. The start position and duration of each gate can be defined by the user, and measurements from two gates can be combined.

Burst Power Mode
Burst power mode enables fast capture and measurement of burst power over large cycles by configuring the normal trigger mode.

Statistical Mode
The CCDF statistical measurement mode calculates the percentage of power that exceeds or is equal to a specified threshold.

External Trigger Functions

By connecting an external trigger signal via a trigger cable, the system can achieve stable triggering of low-power signals. Timing measurements can also be initiated based on the external trigger signal.

Wider Operating Temperature Range

The 2439D Microwave Power Meter and compatible USB power sensors operate across a temperature range of -10°C to +50°C. They maintain consistent power measurement accuracy at temperature extremes as well as under standard ambient conditions.

Optional 2U Rack Mount Kit

An optional 2U standard rack mount kit is available for the 2439D, making it easier to integrate the instrument into rack cabinets and automated test systems.

Battery Option

When fully charged and connected to two power sensors, the 2439D Microwave Power Meter provides at least 5 hours of continuous operation. This makes it well suited for field testing and mobile measurement applications.

Extensive Programmable Interfaces

The 2439D includes standard LAN, USB and GPIB interfaces. The LAN interface supports Socket, VXI-11 and HiSLIP protocols, as well as network auto-discovery, enabling efficient instrument networking and remote control.
