The Instrustar MDSO-LA is a USB-based, same hardware as YiXingDianZi MDSO except that add the logic analyzer and a double eeprom to provide 2 different VID/PID.
- 2-channel oscilloscope with an analog bandwidth of 20MS/s and 48MS/s sampling rate,
- 8/16-channel logic analyzer with a max. sampling rate of 24MHz.
Hardware
- USB: Cypress CY7C68013A-100AXC (FX2LP) (datasheet)
- 256-byte I²C EEPROM: 2x Microchip 24LC02BI (datasheet)
- 16-Bit bus transceiver with 3-state outputs: TI SN74LVC16245A (datasheet)
- 8-channel analog mux/demux: 2x NXP 74HC4051D (datasheet)
- 1A low-dropout voltage regulator (3.3V): Advanced Monolithic Systems AMS1117-3.3 datasheet)
- 2W, fixed input, isolated & unregulated dual/single output DC/DC converter: Mornsun A_S-2WR2 (A0505S-2WR2) (datasheet)
- ADC 8-bit, 40MHz, dual ADC: Analog Devices AD9288 (datasheet)
- 1.4GHz current feedback amplifiers with enable: 2x Intersil EL5166 (datasheet)
- 145 MHz FastFET Opamps: 2x AD8065: (datasheet), markings "HRA"
- Crystal: 24MHz
The device has a switch. Depending on the position it comes up with different USB VID/PIDs:
- MDSO-LA: See YiXingDianZi MDSO/Info for more details (such as lsusb -v output) on the device (used for oscilloscope mode).
- Saleae Logic: 0925:3881 Lakeview Research Saleae Logic (Saleae Logic VID/PID, so fx2lafw works out of the box)
