1 OVERVIEW
The USBscope50 is an isolated digital storage oscilloscope that has
the following features:
• Single channel scope with BNC input and USB PC interface
• Each USBscope50 can be stacked to increase channel count (each
requires its own USB connection)
1
• 300V Cat II isolation between BNC ground and USB ground
2
This means that there is no DC path through the USBscope50
from your scope ground clip to the PC’s ground
• 50MSample/sec single shot sample rate
• 1GSample/sec equivalent sample rate
3
• Timebase from 4ns/div to 4s/div in 1,2,4 steps
• 75MHz 3dB analogue bandwidth
4
• 3000 sample points, 8-bits per sample
• Pre and post triggering
• AC and DC coupling
• Input sensitivities with x1 probe are 30mV/div, 300mV/div,
3V/div and with x10 probe are 300mV/div, 3V/div, 30V/div;
Input ranges provided by the software from 2mV/Div to 10V/Div
in 1,2,5 steps
• 1Meg input impedance, 16pF
• Channel offset control
• Hardware triggering with >, <, +, – modes
• Refresh or Roll modes for display, depending on timebase
• Host powered from USB (200mA typ)
• Stacked configurations of 2,3 and 4 channels are supported
• Stacked configurations allow any channel to be trigger channel
• Stacked configurations have tight phase locking between
channels
• Probe compensation output, 3V 1KHz
• Power/activity LED
1
A stacking connector pair is required
2
In stacked configurations the channels share a common ground at the BNC terminals
3
Suitable to measure repetitive signals that are not phase locked with the internal acquisition clock
4
Hardware trigger bandwidth is approximately 60MHz
