Zurich Instruments launched the first-ever synchronous digital boxcar averager with the UHF-BOX on its UHFLI 600 MHz Lock-in Amplifier, setting a new benchmark for precision in signal analysis.
Proven Technology, Guaranteed Performance
Unlike traditional analog boxcar averagers that depend on trigger-controlled gate windows, Zurich Instruments' digital boxcar averager uses advanced data processing to create an almost perfectly rectangular boxcar window. By synchronizing the gate window to the phase of internal oscillators, they also eliminate common limitations such as trigger re-arm delays and jitter.
With the MFLI 500 kHz / 5 MHz Lock-in Amplifier’s MF-BOX Boxcar Averager option, Zurich Instruments is thrilled to introduce this tried-and-true technology to a wider audience. Making high-performance boxcar averaging for pulsed measurements more widely available allows for a higher signal-to-noise ratio at a more convenient entry point.
