Waveform parameter measurements shall be possible including at least max, min, peak-to-peak, RMS, mean, period, and duty cycle measurements on raw data or waveform math data. DSP calculations shall be capable of being displayed as a trace, displayed numerically, used as a trigger source, and/or stored to memory. Antialiasing digital filtering shall be possible. This shall be no worse than 0.01 dB passband ripple and transition within an octave to 72 dB rejection. Cutoff frequencies shall be programmable from 1/4 to 1/40 of the sample rate. Data recorders shall allow scaling of each analog channel to allow user-defined waveform names, channel units, scale factor and offset. Each of the 32 digital input channels shall be fixed threshold TTL, slope shall be selectable from either +/- level, or +/- edge, and inputs shall have a safe overload rating of at least 130 Vrms. The following specifications shall apply to each of the 4 counter/timer input channels: Each of the 4 counter/timer input channels shall be fixed threshold TTL, functions shall include count up, count down, frequency, rpm, and encoder position. The counter/timer value shall act as an additional signal channel that shall be usable as a displayed trace or numerical value, further processed with DSP calculations, used as a trigger source, and/or stored to disk. Sampling and recording of data shall be possible using an internal timebase or an external clock signal of up to 50 Khz. The data recorder shall be capable of recording at a selectable slow sample rate, then accelerating to a selectable high rate upon a trigger event. Each trigger event shall include a selectable amount of high speed pre-trigger samples and high speed post-trigger samples. Repeated cycles of this low-high-low sampling shall be possible. Triggering shall be possible from analog or digital input data, or DSP computed real-time parameters. Triggering for each channel shall be independently selectable. Trigger slope shall be selectable from positive, negative, or dual. Trigger threshold and hysteresis shall be continuously variable over the input range. Trigger logic shall include and/or combinations of analog, digital and counter/timer inputs. A front panel manual trigger shall be provided. Trigger actions shall include start recording, accelerate recording, or send a triggered segment to an analysis window. Pre-trigger for accelerated recording shall be selectable from 1 to 20,000 points. Post-trigger for accelerated recording shall be selectable from 1000 points to the remaining storage, or it may be terminated when the trigger event goes false. Each trigger event time shall be recorded. Data memory shall consist of standard PC compatible hard disk drives or solid state memory. Data memory shall be sufficient to store all 32 analog channels for 30 minutes with all channels sampled at 100 Khz. Data shall be written to data memory as one or more standard PC data files. Memory architecture and throughput shall allow for uninterrupted maximum rate, 32 channel recording, simultaneous with the following operations: While recalling previously recorded data from the current recording session for display and analysis, while operating any number or type of normal Microsoft Office applications. The data recorders shall be capable of providing an isolated alarm output based on individual thresholds for each channel, or on computed values of the DSPs. The data recorders shall be capable of automatic setup of span and offset for each analog channel based on the peak-to-peak input signals over a period of time. The data recorders shall be capable of playing back, performing measurements upon, and exporting data from one recording, while simultaneously making another recording. Each data recorder shall be controlled by a built-in Intel Pentium computer which has the capability to upgrade the internal processor with a faster processor and capable of upgrading the random access memory (RAM).
