6 Catch transients in durability with high-speed sampling — Dual capture — Recall Past Waveforms — History Function — Measurements with simultaneous high- and low-speed sampling Search by creating a rectangular zone on screen Chattering occurs! To visualize long term trends in durability testing and other situations, data is typically acquired at lowspeed sample rates. On the other hand, suddenly-occurring transitional phenomena should be captured at high-speed sample rates. The "Dual Capture" feature resolves these confl icting requirements by recording at two different sampling rates....

8 16 Ch 16 Ch 16 Ch Plug-in Module DSP Digital Filter Trigger Circuit ACQ memory Math Block { | × ÷ User defi ned computation setup screen Acceleration pickup FFT (power spectrum) Time RPM Time constant The DL850 is armed with a dedicated DSP (digital signal processor) for computations that enables between-channel math during waveform capture. These between-channel computations are powerful because they can be set up separately from fi lter computations. In addition to FIR, IIR, Gauss, and moving average fi lters, you can use arithmetic with coeffi cients, integrals and differentials, and...
