Fluke 9000-Series Interface Pods 电路.pdf

9OOO-Series Micro-System Troubleshooters 收音机爱好者资料库 Ra d i o Fa n s .CN The Interface Pod is the heart of Flukes Micro-System Troubleshooting System, adapting the mainframei general-purpose architecture to the specific micro- processor or microprocessor family. And since the micro- processor is the central control element of the micro- system, stimulating and monitoring board activity with the Interface Pod is the most effective way to functionally test the system. Unlike emulators and development systems which are in- tended fix software debugging, these Interface Pods are designed specifically for troubleshooting hardware fail- ures. They provide discrete control over all processor op- erations that result in pin activity. The user can drive output (control lines and monitor input (status) lines. Even if rhe system has multiple faults, you can continue resting by identifying and disabling faulty lines. This allows you to easily troubleshoot one fault at a time. Because the Pod is intended to be interfaced with defective micro-systems, special input protection circuitry is used. This provides overvoltage protection on each line too the unit under test (UUT) - even if the Pod is plugged in backwards. Other Pod circuitry monitors and checks each read/write operation as it is performed. A self-test socket is included for verifying propcr Pod function. Flukes present line of Interface Pods now support 32 different microprocessor types, a major segment of todays most-widely used microprocessors.

Quick Functions The pods can also pedorm a variety of quick test functions which allow the user to test large blocks of memory very rapidly, with interaction taking place primarily between the pod and the UUT. Quick RAM: Allows a rapid check of RAM space, and consists of two parts: 1. A rapid test of the READIWRITE capability of small segments of memory or the entire block of RAM memory. Performs testing of address lines to insure proper decoding of memory addresses. 2. Pattern Verification test, designed primarily for testing dynamic RAM memory to assure the memory is retaining information property. After a period al time (the duration of which may be selected), the verification part of the test will read the pattern left in RAM from the pre- vious decode test to verify that the data has not changed due to refresh problems in the UUT system. Quick ROM: Designed as a quick test of blocks of ROM using a checksum procedure. The checksum can be used to detect a faulty ROM device with a very high degree of conft dence. The Quick ROM Test will also detect inactive data bits (bits that always read high or low regardlaSS of the ROM address selected). 收音机爱好者资料库 Ra d i o Fa n s .CN Cluick Fill: A last method oi filling memory whrch allows the user to customrre special operatrons, such as might be desirable when testing a memory-mapped video display. There are three variations of thts function available: 1. FILL will write a data byte to all of the addresses in a specified block of memory. An entire terminal memory space can be quickly filled with a particular character by executing the Fill function. 2. VERIN will read data from all of the addresses in the block and compare each one to the data conlarned in the starting address, to ensure that the data has not changed. 3. FILL&VERIFY These two functions can be invoked consecutively with one command. hick Looping: Provides the capabilrty of looprng on a Read or Write command at a much faster rate than that allowed by the loop ing feature of the 9000 Series mainframe. The operator can synchronize an oscilloscope to the address or data timing cycles from the 9000 Series mainframe and observe the timing cycles of the UUT. The BUICK LOOPING functions are particularly useful for enhancing the viewing of signal traces on an oscilloscope because of the increased number of sync pulses coming from the mainframe. hick RAMP (80186 only): Ouick RAMP sends to a particular address a series of data words that start at zero and increment up to FFFF hex. This function executes 65,535 write commands through the pod software, in a very shod period of time. The RAMP function has found widespread application as a stimulus for signature analysis in the Micro-System Troubleshooter. Special Functions: The advanced software in the pod also prop vides several special functions: ? Monrtoring self-test farlure codes 9 Monitoring the last error encountered = Error masking capability 0 Providing Refresh Enable options ?
