The R&S AMU-Z7 manual provides instructions for setting up and operating the analog I/Q combiner, which includes connecting it to R&S signal generators via a USB type B connector for power supply and ensuring proper connection of input and output signals using BNC connectors. It also offers troubleshooting advice, such as using double-shielded cables to avoid electromagnetic interference and ensuring that all inputs and outputs are terminated with 50 Ohms to maintain signal integrity.
Manual Overview
The R&S AMU-Z7 is an analog I/Q combiner designed to integrate multiple I/Q signals into a single output, enhancing the capability of R&S signal generators. It is primarily used to combine signals from different sources, such as the R&S AMU200A, and output them to devices like the R&S SMATE200A. The device is powered via a USB connection to an R&S signal generator and requires double-shielded cables to prevent electromagnetic interference. The device’s inputs and outputs should be terminated with 50 Ohms to ensure proper operation. The R&S AMU-Z7 features a frequency range of 40 MHz and attenuates input signals by 6 dB to maintain output within permissible levels. It is delivered fully calibrated, requiring no further adjustments, and should not be disassembled by users. For troubleshooting, users are advised to contact Rohde & Schwarz support. The device is sensitive to cleaning agents and should only be cleaned with a soft, lint-free cloth. Proper packaging is essential for transportation to avoid mechanical damage.
Quick Issues Covered
- Diagnose power-up failures via USB connection with R&S signal generator.
- Identify and resolve I/Q signal attenuation issues in output.
- Use schematics for circuit tracing and signal path verification.
Overview
The R&S AMU-Z7 is an analog I/Q combiner designed to add two I/Q signals into one, making it a compact solution for combining signals from different sources. It is typically used with R&S signal generators, such as the R&S AMU200A, to combine overlaid signals for further processing. The device supports real-time fading simulation for diversity tests on antennas or MIMO receivers. The manual provides safety instructions, connection guidelines, and operational procedures for the combiner, emphasizing the use of specific cables and connectors to ensure proper functionality and safety.
