The manual for the Rohde & Schwarz SMDU-Z1/Z2 covers the setup and operation of the device as a power measurement adapter and amplitude controller, which can be used independently or to enhance the Universal Measuring Transmitter SMDU for communication devices. It includes features for troubleshooting such as automatic switching of power measurement ranges, connections for additional measuring devices, and outputs for recording modulation degree and HF output power.
Manual Overview
The Rohde & Schwarz SMDU-Z1/Z2 manual provides detailed guidance on the use and maintenance of the amplitude controller and power measurement adapter. It focuses on enhancing the functionality of the Universal Measuring Transmitter SMDU for communication and radio equipment testing. The manual emphasizes the importance of the automatic switching of power attenuation, which is crucial for maintaining accurate measurements. The device supports automatic selection of measurement ranges to minimize errors, and it includes an amplitude modulation degree meter with selectable time constants for various modulation frequencies. The manual also details the integration of measurement equipment, such as analyzers and oscilloscopes, through a 30 dB power attenuation link, allowing for simultaneous connection of multiple devices. Troubleshooting is facilitated by the automatic switching features and the ability to manually engage attenuation when necessary. The manual does not explicitly list error codes but provides guidance on maintaining optimal measurement conditions through proper configuration and use of the device’s features. Calibration and adjustments are primarily automated, ensuring precise and efficient operation.
Quick Issues Covered
- Automatic power range selection minimizes measurement errors.
- Integrated amplitude controller for modulation degree and HF output monitoring.
- Automatic attenuation switching for input power over 0.1 W.
Overview
The SMDU-Z by Rohde & Schwarz is a power measurement adapter and amplitude controller designed to enhance the Universal Measuring Transmitter SMDU for use in radio communication and communication devices. It offers absorption power measurement across five ranges from 0.05 to 30 W or 0.1 to 60 W, and includes a modulation degree meter and low-distortion demodulator for AM signals. The device supports the connection of additional measuring instruments and features power attenuators for reflection-free connections. It can be used independently for measurements on transmitters and power stages within the 1 to 1000 MHz frequency range. The SMDU-Z allows simultaneous connection of up to three different measuring devices and provides automatic switching of power measurement ranges to ensure optimal measurement accuracy.
