 SP3000 General Information |
| Q. | Can the Sp3000 support testing DDR memory ?
| Yes - CST is currently developing an optional DDR adapter which can be pop onto the Sp3000 base tester to support testing the PC2100 and PC1600 184pin DDR DIMM module. |
| | Q. | Can the Sp3000 support testing Rambus RIMM ?
No- the Sp3000 will not be capable of supporting Rambus RIMM module.
Currently - RIMM can be supported on the Eureka 1st Pass tester.
RIMM will be supported by the upcoming CST 's Apollo Memory tester.
|
| | Q. | Will the SP3000-DDR adapter be capable of testing 168pin DIMM ?
| No the 184pin DDR adapter will not be able to test 168pin SDRAM DIMM , since the DDR test socket will not fit the 168pin SDRAM. |
| | Q. | What do I need to test 72pin DRAM SIMM and 168pin SDRAM DIMM ?
The SP3000 tester has a universal base test engine. With the correct test adapter, you can configure it to test both DRAM and SDRAM memory.
The Combo Tester option includes a base tester and two test adapters. The DRAM test adapter test 72pin SIMM and 168 pin DRAM DIMM. It is capable of testing JEDEC standard 72pin EDO and Fast Page & 168pin EDO & FPM DIMM module. The SDRAM test adapter test JEDEC standard 168pin SDRAM PC133 PC100 PC66 unbuffered and RegisteredSDRAM DIMM memory modules at real frequency. Optioinal 30pin SIMM and 144pin SDRAM SODIMM for laptop can be added too. |
| | Q. | What is the test coverage for SP3000 ?
| The SP3000 tester has user selectable test option. For Basic Test, it checks for assembly open and shorts on the module using the Walk address and Walk data test patterns. For detail comprehensive testing, the tester has additional user definable patterns such as Marching, Checkerboard , Preheat, Burst, Voltage Bounce tests to check for dram cell and operations related faults. |
| | Q. | What are the test features of the SP3000 tester ?
For DRAM module testing
Walk Address Test - checks for open/short on address pins and bad address decoder.
Walk Data Test - checks for open/short data bits
Marching & Checkerboard Test checks for bad cells, decoder interaction problem.
Pre-heat Test checks for reliability during chip warming up.
Voltage bouncing test checks for modules with noise related problem
Loop Test to simulate module burn-in situation
For SDRAM Testing:
Has similar test as above and includes the followings :
Burst Test – checks for faulty chip that fail to read&write during consecutive clock cycles.
Chip Select Test – checks for assembly shorts and open on the CS pins
DQM Test – checks for SDRAM chip input and output masking ability
WP Test – check for module that is PC-100/PC133 Intel compliance.

| | Q. | How accurate is the SP3000 tester ?
| The tester detects almost all faults associated with memory module. The tester has an access time (Speed) resolution of 1 nanosecond and It is the tester used by majority of SIMM Module memory manufacturers and Service Depot. |
| | Q. | How fast can memory module be tested with the SP3000 ?
| The SP3000 is able to test a 32MB – 168pin DRAM DIMM module in 2 seconds for quick test (open and short test).A comprehensive detail test (open/short, marching test ) will take under 10 sec to complete . This is the fastest tester compared to other testers that will take 25 sec.
The SDRAM-133Mhz test adapter can perform a detailed test on a 32Mb PC100 SDRAM DIMM module in less than 8 sec flat as compared to other tester that will take more than 20sec. |
| | Q. | Can the SP3000 automatically identity any module ?
| With the correct test adapter attached to the base unit, you will be able to detect an entire array of memory module for size, number of data bits, access time (speed) etc. There's no guess work on your part. The SP3000 will Automatically-Identify all JEDEC standard module, for size/capacity, device configuration, access time (speed), parity / non parity/ ECC /3.3V/5.0V voltages and more. |
| | Q. | Can it test PC133 modules ?
| Yes, with the SDRAM 133mhz test adapter, it has user selectable frequency option from 66mhz - 133mhz to test PC133 PC100, PC66 SDRAM DIMM module. If you do not know the frequency, do not worry! The tester can automatically detects the frequency for you too! |
| | Q. | How is the SP3000 compared with the Competition ?
The SP3000 is the most preferred tester used by many SIMM/DIMM manufacturer / OEM and Service Depot customer such as Samsung, HP, Micron, Compaq, Dell, CompUSA, Frys and more..
The SP3000 won the Reader ‘s Choice Award for Best Low Cost ATE Tester Solution in EE magazine (Evaluation Engineering)
The SP3000 is very easy to upgrade with optional plug-on test adapters.
Field upgradable with easy PC Control and Free Firmware download from the Internet.
User friendly test menu for “non –technical user”.
Compact, portable and standalone with universal switching power supply. |
| | Q. | How can I update my tester for future release?
For Hardware upgrade to a different memory module type testing, the tester can be easily configured by purchasing the appropriate plug-on test adapter to the base tester.
For Firmware upgrade, an optional PC Interface Kit is available which allows user to download the firmware directly into the tester at the convenience at your location. |
| | Q. | Does SP3000 require a PC connection ?
| No, the tester is designed as a complete standalone unit and connection to PC is easily available with an optional PC Interface Kit & software. The PC will provide enhanced display of results & allow on-line firmware upgrade for future revision change |
| | Q. | Can the SP3000 print test results ?
Yes , the SP3000 has a printer port located at the rear of the tester, it can be connected to any printer directly with a printer cable. The fail results will be printed out upon enabling the print function.
