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
