Velleman PCSU250

The PCSU250 is an inexpensive USB-based oscilloscope. It has 2 channels, an analog bandwidth of 12MHz and 25MS/s sampling rate. Additionally a signal generator is included.

See Velleman PCSU250/Info for more details (such as lsusb -vvv output) about the device.

Hardware

Control logic

USB interface

  • Inluded in the PIC.

Analog frontend

Power

Trigger Level

  • 74HCT4051D 8-channel analog multiplexer/demultiplexer with 15 resistors, is that a R2R DAC??? I would guess this one is for the trigger level

Signal Generator

  • DAC0800LCM 8-Bit Digital-to-Analog Converter Settling Time 0.1 µs, does that mean max. 10Mhz Sample rate?
  • TL081C JFET OPAMP
  • lm6172 Dual High Speed, Low Power, Low Distortion Voltage Feedback Amplifiers 100Mhz GBW

Photos
