Laser Lock Box (New instrument)

• This instrument can be used to stabilize a laser’s frequency to a reference cavity or atomic transition using high-performance modulation locking techniques.
• Generate and output modulation signals at up to 200 MHz
• Demodulate the input signal with an internal or external local oscillator including a phase-locked loop option
• Scan across resonances with sawtooth or triangle waveforms at up to
  1 MHz
• Quickly lock to any zero-crossing in the error signal using the
  ‘tap-to-lock’ feature
• Filter the demodulated input signal with up to fourth order
  infinite-impulse response filters
• Individually configure fast and slow PID controllers
• Observe signals at different stages in the signal processing chain
  using an in-built oscilloscope

Arbitrary Waveform Generator

• Now supports triggering, with N-cycle and Start burst modes which can be triggered using an external trigger signal.
• You now have full control over the number of points, update rate and interpolation of waveforms.
• There is also a new cardiac waveform for simulating ECG patterns, and a new graphical piecewise equation editor which makes building custom waveforms easier than ever.

Digital Filter Box

• Adds extended ranges for lowpass, highpass and bandstop filters, allowing corner frequencies up to six orders of magnitude below the sampling rate.

General

• New-look main menu with options to connect to a recently-used device, switch instruments directly or open the file manager to view, upload and share data files on your device.
• Minor bugfixes, interface improvements and performance enhancements.
