DSP panel and bargraph readings display theKreal time peak input to allow setting of levels. When the DSP AMPLitude isEgraphed on the sweep panel vs DSP TIME an oscilloscope display of theFwaveform will result. A selected piece of the acquired signals may beLtransformed with an FFT to see the frequency spectrum. The beginning of theJpiece to be transformed is set with the FFT START time field on the panel.ITo display the frequency spectrum select a graph of DSP AMPL vs DSP FREQ.LThe F9 function key causes a new data acquisition and transform. The F6 keyJcauses previously acquired data to be transformed. The acquisition may beHtriggered by the positive or negative transition of any one of the inputGsignals. Data may be acquired before the trigger event by selecting a LPRE-TRIGger time less than zero. The maximum acquired record is 8192 pointsKwith standard memory, 30720 points with full memory. The maximum transformJlength is 4096 points with standard memory, 16384 points with full memory.KBH4 selects a Blackman-Harris 4 term minimum sidelobe window, HANN a raisedDcosine, FLAT has less than 0.02 dB rolloff, NONE gives no windowing.MCAUTION: DSP Panel readings must use %FS or dBFS. F7 does not allow units toMbe changed, use F6. DATA1 and DATA2 must not be the same (AMPL-1 or AMPL-2).MAt the 1k sample rate, acquired length equals 1.5 times the FFT input length.v\EC0yjp: Q!e j&Ufϴy5!U V V V ե  ?U j $~+S[cs*cs3.U > U _  U ' W U e:._UU<R  _U [Y! g GM*N ::{:{@/M/D/ /(\uDd%vX '9 <9 x h  PM Me'L0IeN2 {' N"'B@/M/ \eETM~T4O!\$A@~\CgAmA"IέIs FCGC~A'bL/afdf`d& CLNPfz( . ayeۓ؛%@ZmMdoGC%@ٔ} oGD=A( %@ڥ"#3(%!8Cj0n( . ayeۓ؛%@Z} oGD=A( %@wsdd` p66"ka)M,L8cBJa0M5L8c)$e x#`b)`A*  x  k` x[ $fI%j `d&HCP) M" &˳S F%P%''G$$y%@!
