The Rohde & Schwarz SMDU operation manual provides detailed instructions for setting up, operating, and troubleshooting the UNIVERSAL-MESS-SENDER, including specific guidance on frequency adjustments, modulation settings, and measurement techniques. It also outlines procedures for checking equipment functionality, such as frequency stability, modulation distortion, and output voltage, to ensure optimal performance.
Manual Overview
The Rohde & Schwarz SMDU operation manual provides detailed instructions for the Universal Measurement Transmitter, focusing on troubleshooting, error diagnostics, and calibration. Troubleshooting involves checking the readiness of the deviation meter, indicated by LED 26, which lights up when the carrier frequency is within the tuning range. If the meter tunes to a harmonic, the instrument may show increased noise or useful deviation, which can be avoided by verifying frequency with counter 3. For devices with modulation units numbered 870 444/26 or higher, the DEVIATION FREQUENCY indicator is omitted. Calibration requires setting the counter to NF-INT to display the frequency of the signal processed in the modulation unit, though accuracy is not guaranteed at low display levels. Board-level adjustments include replacing operational amplifiers and removing specific resistors in the impedance converter. The manual also details the removal of the phase shifter auxiliary board, with certain components relocated to the motherboard and front panel.
Quick Issues Covered
- Diagnose frequency deviation using LED indicator and counter.
- Adjust frequency shift for 1.05 GHz extension module.
