Recently, a college sent a repair Rod and Schwarz power amplifier BBA150, and the customer feedback output was incorrect, and the instrument was preliminarily tested, and it was determined that the fault described by the customer was basically consistent. In this issue, we will share this repair case with you.
Here's how the Rohde & Schwarz-BBA150 was served.
The output of the power amplifier BBA150 is repaired when the error is reported
1. Power amplifier maintenance model: Rohde & Schwarz BBA150.
2. Repair failure: The output is reported as an error and the signal cannot be amplified.
3. Fault detection: If the instrument fails to self-test, the internal components will be tested in detail according to the error information analysis. The dust accumulation inside the instrument is serious, and it is determined that the power amplification module is faulty.
4. Maintenance measures: replace damaged components. Perform a self-test. All of them are tested. And the whole machine is tested on the instrument, the internal dust is cleaned, the self-calibration passes, the test signal is normal, and the indicators are qualified.
Antai maintenance comprehensive inspection to confirm that there is no problem with the instrument and return it to the customer.
When there is a problem, be sure to find a professional and reliable power amplifier repair center for after-sales maintenance. The following is a list of the main features of the BBA150 compiled by the Antai Maintenance Center:
Frequency range: 4 kHz to 6 GHz
The 1 dB compression point output power ranges from 15 W to 3000 W
100% mismatch tolerance.
Suitable for amplitude, frequency, phase, pulse, and OFDM modulation.
A variety of switching options are available for flexible system configuration.
Deep expertise in amplifier development
The R&S BBA150 wideband amplifier covers five frequency bands: 9 kHz to 250 MHz, 4 kHz to 400 MHz, 80 MHz to 1 GHz, 069 GHz to 32 GHz and 25 GHz to 6 GHz. The instrument can be used to solve a variety of application problems, including multiple standards for EMS measurements up to 6 GHz. In industrial environments, the R&S BBA150 wideband amplifier is suitable for quality assurance as well as development and product validation testing in component development and production. The amplifiers are also suitable for other applications such as research, physical engineering, and communications. The amplifier's compact, modular design supports single or multi-band configurations, making it suitable for use as a 4 HU desktop unit or as a 19 installation"rack to provide high power.
