USB BitScope 310 - PC Oscilloscope

BS310U is a robust general purpose USB Mixed Signal Scope and Data Acquisition device. BS310U is backward compatible with BS300U which it replaces.

USB BitScope 310 - PC Oscilloscope
 
It has 4 times as much capture buffer, a software switchable x10 and x50 analog input multiplier and AC/DC coupling, switchable 50 ohm termination, a double speed built-in USB host interface all in a physical package about 2/3 the size and weight of BS300U.

USB BitScope 310 - PC Oscilloscope

  • 100 MHz Analog Bandwidth Scope.
  • 40MS/s Logic Analyzer, 25nS capture.
  • Dual Analog Channels (4 inputs via BNC & POD).
  • 8 logic/timing channels and Smart POD.
  • Arbitrary Waveform Generator.
  • Real-Time Spectrum Analyzer.
  • Mixed Signal Data Recorder.
  • Networkable (BS310N).
  • User Programmable.
BitScopes are USB or Ethernet connected PC Based Mixed Signal Oscilloscopes. This means they capture and display one, two or four analog signals and eight logic or timing signals, simultaneously.

MSO-19 - Mixed Signal Oscilloscopes - Link Instruments

A Mixed Signal Oscilloscope (MSO) is a combination Logic Analyzer and Oscilloscope. Since all inputs sample simultaneously, it is easy to see the timing relationships of the digital and analog components of your circuit.

MSO-19 - Mixed Signal Oscilloscopes - Link Instruments

The palm-sized MSO-19 operates as a 2 GSa/s Oscilloscope, a 200 MSa/s Logic Analyzer, a 100 MSa/s Pattern Generator, and a Time Domain Reflectometer (TDR). All channels sample simultaneously at a max rate of 200 MSa/s.

MSO-19 - Mixed Signal Oscilloscopes - Link Instruments

Time synchronized Oscilloscope and Logic Analyzer inputs.

All 9 channels are sampled at the same time and are displayed together. This is better than separate instruments because the analog and digital waveforms are acquired with the same sample clock, assuring accurate time correlation between the two.

Link Instruments

They design and manufacture portable Logic Analyzers and Digital Storage Oscilloscopes. Over the years, we have added Pattern Generation and Spectrum Analysis.
