Ordering Information
Manuals, etc.

Low-EMI PulseBlasterUSB is a low electromagnetic interference version of our PulseBlasterUSB. This system features a low noise power supply, shielded enclosure, 8 output channels through TNC connectors and an external clock input connector.

Key Specifications

  • High performance, filtered AC power entry module.
  • Low-noise 3A linear power supply.
  • Custom enclosure with enhanced shielding.
  • TNC connectors for each output channel.
  • External clock input (1kHz to 50MHz).
  • Slowed slew rate of the output pulses.
  • Reduced 12mA output current per channel.
  • 8 Programmable Digital Output Bits (20ns resolution @ 50 MHz).
  • Automatic USB communication shutdown at low clock frequencies (below 50 MHz)


Complex multi-channel pulse generation where Low-EMI functionality is critical. Examples may include:

  • Experiment and process control in Electron, Nuclear and Quadrupole Resonances (ESR, NMR, NQR)
  • Mass Spectrometry and related test technologies
  • Ultrasound, radar, medical imaging
  • Laser control in advanced communication
  • Solid state physics experiments
  • Nanomagnetism and spintronics applications
  • Robotics and process synchronization
  • Complex Pattern Generation
