JS9500(SD/DDR/DDR2/DDR3)
memory tester can work on SDRAM, DDR, DDR2, DDR3 Memory
Module & Memory Chip.
Feature:
Auto Identify Memory Type, Memory Size, Memory Frequency and
Auto Testing on this frequency. Address depth: 16 Giga-word
( 18 Row x 18 Col). Data width: 64 bit. Colored LED for
Test, Pass and Fail status to each 64bit data and address &
controller.
Auto
Identify:
- Memory Configuration: SDRAM DDR DDR2 DDR3
- Memory Size: 64MB 128MB 256MB 512MB 1GB 2GB
4GB 8GB 16GB
- Memory Frequency: all Clock
Frequency
Real
Bus Speed Testing
- Real Cycle Time and At-Speed Testing
- Uses state-of-the-art SDRAM DDR DDR2 DDR3
controller
- Super Fast Test time( 512MB in 8secs)
Effective
Test Algorithm:
- Automatic Read/ Write Leveling
- checks for assembly faults
- Detail March test, checks for functional
failures
Fault Focusing – pinpoints to faulty chip(s) Ease of Use:
- Easy to read LED display
- 1 Easy Push Button Selection A bank and B
bank
- Colored LED for Test, Pass and Fail status
- Universal power supply(AC22OV/11OV)
Address depth:
16 Giga-word (18 Row x 18 Col)
Data width:
64 bit
Weight:
4.5KG
Operating Notes:
Please insert the memory module and open the
power, the program operating auto start and run to test the
directional data.
(for the double bank of the memory module,
the tester will test A and B by two times, for the single
bank, test A only one time.)
For the double banks of the memory module,
you must shut off the power, when you finish to test the one
bank, then change to the other bank, open the power again,
the testing software will download and test it.
TEST (LED)
Red LED (TEST) to be put out, means test
complete
MEMORY SIZE:
64MB, 128MB, 256MB, 512MB, 1G, 2G, 4G, 8G
indicating yellow LED: in a LED, 16G indicating in two LED
by 4G and 8G at the same time.
Observing the failure:
Address fail:
observing 18 row x column normal or not,
Normal: 18 pieces of yellow light in a diode
indicator is flash or on
Fail: indicator is off., which located on A0——A14
BA0 BA1 BA2.
Data fail indicator
Green LED is on: data fail
Green LED is off: data normal (pass)
Red LED is keep on: data short-circuit coming
to the power (VDD)
Red LED is keep off: short-circuit or break
off for the ground (VSS)
Red LED is change for on and off: normal
Service
Clause:
1. Freely repair for one year for memory
tester only.
2. Repair for the whole life( pay working
charges after free repair).
3. Do not open the memory tester, we do not
freely repair it after you destroy the seal.
4. Be careful of use the selected accessories
and the memory trough.
