Manual Overview

The HP 8340A/B and 8341A/B Attenuator Calibration Operating Manual provides detailed guidance for calibrating and verifying the operation of the attenuators in these synthesized sweepers. The manual includes a test software (HP Part Number 08340-10009) that facilitates semi-automated operation verification and complete calibration of the 90 dB step attenuator. This software is designed to ensure a 90% confidence level in the synthesizer’s operation, making it suitable for incoming inspections or post-repair verifications. Key performance tests include CW frequency accuracy, output power accuracy and flatness, and maximum leveled power. The manual also covers phase lock loop diagnostics and ALC accuracy verification. Technicians are guided through the calibration process, which involves adjusting and verifying the performance of the internal attenuator. The manual emphasizes the use of specific test equipment and provides procedures for entering calibration data and running diagnostic tests. The document also includes troubleshooting flowcharts and error diagnostics to assist technicians in identifying and resolving issues at the board level.
