The Transparent Absorbing Wave Temperature, Humidity, and Vibration Test Chamber is a high-end environmental simulation system engineered for integrated reliability testing. It distinguishes itself by combining traditional environmental stressors—temperature, humidity, and vibration—with specialized electromagnetic wave transparency and absorption capabilities. You can utilize this chamber to simulate the complex operational environments faced by electronic systems, allowing for the simultaneous application of thermal cycling, moisture, and mechanical vibration while maintaining the integrity of RF signals. This multi-stress approach is essential for identifying latent design flaws in high-frequency communication equipment and radar components before they reach the field.
The Transparent Absorbing Wave Temperature and Humidity Vibration Test Chamber is a high-end testing device capable of simulating complex environmental conditions. It is particularly well-suited for reliability verification in fields such as aerospace, aviation, and automotive electronics. By superimposing temperature-humidity cycles with vibration stress, it rapidly exposes potential defects in products during transportation or use.

The standard and optional accessories available for your test requirements include:
Vibration interface platform and mounting fixtures
High-strength adhesive bonding system for transparent wave door installation
High and low temperature resistant absorbing wave materials for internal chamber surfaces
Temperature and humidity sensors with calibration support
Safety protection and monitoring modules
To conduct a standard combined environmental test, you should follow these steps:
Install the test specimen securely on the vibration platform and connect required power and signal interfaces.
Set the desired temperature, humidity, and vibration profiles according to the test specification.
Start the temperature and humidity control system and allow conditions to stabilize.
Activate the vibration system and run the combined environmental test for the specified duration.
Monitor key parameters throughout the test and record all relevant data.
After test completion, return the chamber to ambient conditions before removing the specimen.
1.How does the transparent wave door affect electromagnetic test accuracy in the X-band?
The transparent wave door is specifically designed for X-band applications with a transmission rate greater than 95 percent. Its low reflection design ensures minimal impact on electromagnetic field distribution, and the standing wave influence is controlled below 2 percent. This allows you to perform reliable RF and microwave performance testing without compromising measurement accuracy.
2.Can you perform powered testing on samples during combined temperature, humidity, and vibration conditions?
Yes. The chamber supports powered testing across a wide temperature range. Within -55 °C to +85 °C, you can operate test samples with up to 8000 W of internal heat dissipation. During temperature soak conditions, the system allows 3500 W heat dissipation while supplying controlled cooling air, enabling realistic operational testing under combined environmental stresses.
3.What precautions should you take when testing high-power RF devices inside the chamber?
When testing high-power RF devices, you should ensure that the power density does not exceed 10 W per square centimeter, which is the rated endurance limit of both the transparent wave door and the absorbing wave materials. Proper cable routing, secure grounding, and continuous monitoring of internal temperature rise are recommended to maintain test safety and result stability.
4.How does the absorbing wave material reduce standing wave effects during testing?
The absorbing wave materials installed on the front, left, and right inner surfaces near the transparent wave door provide more than 25 dB attenuation in the X-band. This significantly suppresses electromagnetic reflections within the chamber, reduces standing wave formation, and improves the consistency of electromagnetic exposure during testing.
