1、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 c

2、entral 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 specificall

3、y 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 disabli

4、ng 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 plu

5、gged 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 m

Quick Functions The pods can also peform 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 tw

16、o 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 i

17、s 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

18、 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 confi- dence. The Quick ROM Test will also detect inactive data bits (bits that always read high or low regardless of the ROM address selected). 收音机爱好者资料库 R

19、a d i o Fa n s .CN Quick Fill: A last method of filling memory which allows the user to customize special operations, such as might be desirable when testing a memory-mapped video display. There are three variations of this function available: 1. FILL will write a data byte to all of the addresses i

20、n a specified block of memory. An entire terminal memory space can be quickly filled with a particular character by executing the Fill function. 2. VERIFY will read data from all of the addresses in the block and compare each one to the data contained in the starting address, to ensure that the data

21、 has not changed. 3. FILL&VERIFY These two functions can be invoked consecutively with one command. Quick Looping: Provides the capability of looping 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

22、an oscilloscope to the address or data timing cycles from the 9000 Series mainframe and observe the timing cycles of the UUT. The QUICK 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 t

23、he mainframe. QUick RAMP (80186 only): Quick 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 applica
