Troubleshooting Guide Overview This troubleshooting guide is divided into three sections. The section that you use will be determined by the items available to you for use in troubleshooting. Section 1 allows for limited troubleshooting due to limited availability of items. Section 3 is the most complete troubleshooting section. Section 1: Bass Box Only Procedures is to be used if you have a bass module to troubleshoot, but no head unit or PC to turn the bass module on. It will take you through a troubleshooting process which will allow you to power up the TV Multimedia">Amplifier PCB by itself, as well as some troubleshoot- ing procedures for the Digital Signal Processor PCB, should it be at fault. Section 2: Bass Box with a Head Unit Procedures is to be used if you have a bass module and a head unit, but no PC. In this section you will be able to connect an audio signal to the head unit and turn the bass module on. This will allow you to signal trace and troubleshoot the TV Multimedia">Amplifier PCB and the Digital Signal Processor PCB. Section 3: Computer Aided Troubleshooting Procedures is to be used if you have a PC that can be used to communicate with the Digital Signal Processor PCB of the bass module, and is the preferred method of troubleshooting. In this section you will be able to determine the EQ curve of the module under test as well as put the module into different test modes for easier troubleshooting. There is an Appendix at the back of this guide containing information such as simplified schematic diagrams, block diagrams, frequency response curves, tables, and computer setup information. See the table of contents for a complete listing.


Equipment information

Fluke 5100B Calibrator
Model: 5100B
Date: 1990
Category: Measurement instruments
Group: Calibrator
Description: Calibration Instruments

The 5100B Series Calibrators are the world's leading calibrators for analog and digital multimeters to 41/2 digits. Dependability, five-func- tion versatility and cost effectiveness have made the 5100B Series Calibrators Basic equipment for nearly every calibration laboratory. Now these calibrators offer even more value. DC voltage uncertainty is 40 ppm; Basic AC uncertainty is 350 ppm. The front panel includes high-voltage safety terminals together with control grouping optimized for user friendliness. Quality and reliability are also enhanced with modern manufacturing methods including statistical process control (SPC). The versatility of the 5100B Series Calibrators is unmatched at any price. They are compatible with the popular Fluke 7411C and MET/CAL based Calibration Systems, the Navy's MECCA Systems and the new Fluke 5700A Multifunction Calibrator. Enhanced capability is also available with the 10 MHz Wideband Option and the capability to directly drive the Fluke 5220A 20A Trans- conductance Amplifier and the 5205A or 5215A High Voltage Amplifier. 5100B Series Increases Throughput A large share of the workload of meter calibration laboratories and production lines consists of analog and digital meters with 472 digit or less resolution. There are hundreds of different meters in this category representing different manufacturers, with no standard format for meter specifications. Operating the 5100B Series is simple, making it easy to train your operators. And all data is entered via a calculator-type keyboard. No need to convert volts to dBm or dBm to volts, for example. And the 5100B Series performs the mathematical computations associated with calculating the error of the unit-under-test (UUT) - in % or in dB. It then indicates to the operator whether the UUT passed or failed, according to its specified uncertainty and the magnitude of the error. The 5100B Series calibrates meters quickly and efficiently. It is no longer necessary to gather together separate calibration instruments requiring complex interconnection and operation. A single 5100B Series does the whole job.
