The following data illustrate the EXCELLENT Time-Domain performance of the ASC USB 2.0 Multi-Channel PC Recorders.
ALL DISPLAYS are actual UAD-1800-16it 18-channel 250 Ks/s 16-bit MC-PCRŽ screens; the signal generator is a Tektronix SG5010 Low-distortion Programmable Signal Generator:
(Don't try capturing/recording these waveforms on the Competition's 20Khz/40Khz bandwidth digital instrumentation recorders!)
NOTE the excellent filter ringing behavior that approaches theoretical performance for the 100Khz-bandlimited data capture (6th order reconstruction (display) filters).
(PAUSED for CURSER MEASUREMENT): 40Khz 2-cycle toneburst input
(Expanded display of Channels 1, 3, and 5; 1ms Display Window/1 Khz Spectral Resolution)
CH1: 250 Ks/s with 100Khz post-filter; CH3: 250 Ks/s power spectrum (Hanning Window); CH5: 250 Ks/s with 70Khz post-filter
NOTE the excellent toneburst performance with near-perfect burst rise, practically NO visible burst distortion and minimal post-ringing at the Full Capture Bandwidth (100 Khz). This indicates excellent ability to capture accurately high-speed transients.
(PAUSED for CURSER MEASUREMENT): 40Khz 3-cycle toneburst input
(Expanded display of Channels 1, and 3; 1ms Display Window/1 Khz Spectral Resolution)
CH1: 250 Ks/s with 100Khz post-filter; CH3: 250 Ks/s power spectrum (Hanning Window)
NOTE the excellent toneburst shape with near-perfect burst rise characteristic, practically NO visible burst shape distortion, and minimal post-ringing. This indicates excellent ability to capture accurately high-speed transients.
