Safety Instructions
How to Prevent Risks
Observe applicable local or national safety regulations and rules for the prevention of accidents. Ensure that R&S ATS‑TEMP, hoses, and adaptors are well-sealed before operation inside R&S ATS1000. Ensure that the personnel wear protective clothing (work clothes and gloves). Disconnect the DUT from power before touching/removing it from R&S ATS‑TEMP. Use the R&S ATS‑TEMP only for its intended use and within its performance limits. If you are unsure about the appropriate use, contact Rohde & Schwarz service.
Environmental condition Observe the operating conditions specified in the data sheet.
R&S ATS‑TEMP condition Use the R&S ATS‑TEMP only if it is in excellent condition. If you detect or suspect any irregularities, malfunctions, damage, or temperature leakage; immediately stop using the R&S ATS‑TEMP and inform Rohde & Schwarz for a service check.
Modifications Never change or modify the climate option for R&S ATS1000 or make additions that can affect safety.
Safety stickers Do not remove the safety stickers on the outside of the bottom shell of the R&S ATS‑TEMP. Always keep the stickers visible. If the stickers peel off, you must replace them. Contact Rohde & Schwarz local support to order new stickers.

1.3 How to Prevent Risks

How to prevent burns caused by hot steam
When opening the R&S ATSTEMP, hot steam can escape and scald you.
To prevent burns:
► Wait until the surface of the dome of R&S ATSTEMP is at room temperature
before opening and use heat/cold resistant gloves.
How to prevent burns or frostbite caused by hot or cold surface
Depending on operation during extreme temperature testing, the surfaces of the OTA Bubble, mast, hoses, and the DUT can be very hot or very cold. You can suffer from burns or frostbite, if you touch these surfaces. Especially, be aware that your fin­gers can freeze to a surface at temperatures below 0° C.
To prevent burns and frostbite:
► Allow the R&S ATSTEMP to adjust to room temperature before touching.
► Use heat/cold resistant gloves when touching any hot or cold parts.

Safety Instructions
Safety Labeling
How to prevent intoxication and injury due to explosion
When loading the R&S ATS‑TEMP with an unsuitable DUT, toxic or explosive gases can be produced. These gases can cause the R&S ATS‑TEMP to explode and injure you. Toxic fumes can escape and lead to intoxication.
To prevent the formation of dangerous gases:
► Load the R&S ATSTEMP only with materials/DUTs which do not form any toxic or
explosive vapors when heated up.
How to prevent risk of injury due to operation of a thermal device
Operating a thermal device includes risks of temperature-related injuries.
To prevent these risks:
► Carefully read the safety instructions of the thermal device used.
► Limit the thermal device to the temperature range from -60°C to +105°C.
Temperatures outside of this range can damage the equipment and lead to injuries. Note that the R&S ATS‑TEMP and the R&S ATS1000 do not control the thermal device. Therefore, temperature limitation is in your responsibility.

1.4 Safety Labeling

Safety labels on the product warn against the potential hazards.
Hot surface
Do not touch. Keep the operation area dust-free.
Risk of skin burns. Risk of fire.
Cold surface
Do not touch. Risk of frostbite.
Electrical hazard
Indicates live parts. Risk of electric shock.
Danger of hot vapors or scaling
Load the R&S ATSTEMP only with materials/DUTs which do not form any toxic or explosive vapors when heated up.

2 Product Description

Product Description
Key Characteristics
The R&S ATS‑TEMP is a climate option for R&S ATS1000. This Rohde & Schwarz product allows 3D RF measurements of antenna characteristics in a temperature range from -20 °C to 85 °C to analyze temperature effect on the chipset and UE performance. The provided measurement conditions are suitable for tests at extreme temperatures and extreme temperature ranges.
The R&S ATS‑TEMP operates mounted in an antenna test system R&S ATS1000. A current version of R&S ATS1000, which has a false-floor plate with predefined holes in it, supports the climate option for R&S ATS1000. A retrofit of an older R&S ATS1000 chamber to this thermal solution must be performed by Rohde & Schwarz service.
The R&S ATS‑TEMP is designed for operation with thermal test device to be connec­ted to the hose adaptors of the R&S ATS‑TEMP. The thermal test device uses hot or cold airstream. It controls the temperature via its temperature sensors placed in the R&S ATS1000 chamber.
Rohde & Schwarz recommends the thermal device TA-5000A to be used with R&S ATS‑TEMP. With this thermal test device, all connectors match.
This user manual contains a description of the functionality that the R&S ATSTEMP provides. The latest version is available for download at the product homepage (www.rohde-schwarz.com/product/ats1000).

2.1 Key Characteristics

The R&S ATS‑TEMP consists of an RF transparent material which minimizes the influ­ence to the radiated measurements (< -1dB for 5G NR for 22 GHz to 45 GHz). Due to its compact design, the R&S ATS‑TEMP results in fast and precise 3D measurements with excellent repeatability and angular resolution.
The key characteristics of the R&S ATSTEMP are the following:
Table 2-1: Specification
Parameter Value Comments
Outer dimensions 30 cm Diameter
Inner dimensions (max. DUT size) 22 cm x 22 cm
Operational temperature range -20 °C to 85 °C Possible to go to -40 °C for short
Minimum soak time for extreme temperatures before cooling/heat­ing cycle
3 minutes
periods (less than five minutes)
Maximum soak time for extreme temperatures
Dependent on the temperature outside R&S ATSTEMP
If the ambient temperature out­side R&S ATS‑TEMP is above 40 °C, perform a cold temperature cycle to cool the OTA Bubble.

Temperature Operation and Condensation
You can heat up the interior of R&S ATS‑TEMP to 85 °C and cool down to -20 °C.
To prevent condensation, the system has several features:
Sealed hose and adaptors from thermal test device to R&S ATSTEMP.
Patented OTA Bubble design to minimize condensation on outside of the OTA Bub- ble.
Internal drainage for condensation in the OTA Bubble through the hose for air out.
In addition, we recommend using a thermal test device that removes humidity from the airstream before going into the R&S ATSTEMP.
After repeated hot/cold cycles, use a soft cloth to absorb any water condensation in and around the OTA Bubble, hoses, and mast. Place a small bowl at the R&S ATS1000 air out hose adaptor on the lower right side to catch the water. Alterna­tively, attach another hose to the air out hose adaptor to vent the cooled/heated air and condensation to another location.
