FDR-505
Floor
FDR-505 is a large-capacity radio frequency (RF) shielding test chamber engineered for controlled testing of frequency-generating devices in interference-free environments. Designed for expanded test setups, it isolates internal signals while preventing external RF interference, enabling accurate, repeatable performance validation for complex RF systems.
Standout Features:
- High-performance RF shielding blocks external interference and prevents signal leakage
- Independently certified attenuation performance with documented test results
- Shielded pass-through interface plate with RF-rated connectors for device communication
- Integrated environmental temperature control for RF device reliability testing

*Rise and pull-down rates calculated using IEC 60068-3-5 standard. Custom options available.
*Ideal ambient temperature conditions for test chambers is 23°C (73.4°F). The temperature and humidity range of assured performance is between 15°C and 25°C (59°F/77°F) and 30-50% relative humidity. Conditions outside this range may affect the performance of your test chamber and reduce the lifespan of the equipment.
Notice for Customers Requesting R449A:
Consult our sales team regarding the use of R449A refrigerant (where applicable). This substitution ensures compliance with relevant regulations. Please be aware that the use of R449A will change the achievable low temperature to -35°C. Our sales team can provide detailed information regarding this change for your specific application.
