Información

PURPOSE OF THE EQUIPMENT The model 164 Sweep Generator offers an extended waveform versatility plus a frequency range that spans twelve decades, from 30 µHz (9.2 hours per cycle) to 30 MHz. The waveforms available are sine, square, triangle, trapezoidal and positive and negative rectangular and trapezoidal pulse, each with variable amplitude, dc offset and symmetry. The trapezoidal waveform rise and fall times may be varied by means of independent slope, width and symmetry controls. Different rise times and fall times, both controllable, may be selected to suit your testing or triggering | requirements. The model 164 employs a main Generator, which can be J triggered, gated or swept by an external signal. In addition, it has a ramp/step Generator. The latter is used to sweep, sweep burst or step the frequency of the main generator. Frequency sweeping and stepping may be up or down. Steps may be automatically sequenced or triggered. 1.2 SPECIFICATIONS 1.2.1 Waveforms Eight selectable waveforms, sine, triangle, square, positive pulse, negative pulse, trapezoid, positive trapezoid, and negative trapezoid, plus variable DC output. Symmetry of all waveform outputs is continuously adjustable from 1:19 to 19:1. Varying symmetry provides variable duty-cycle pulses, sawtooth or unsymmetrical trapezoidal waveforms. Separate sync output included. Sweep Generator ramp and steps for continuous or discrete-step sweep; up or down sweeping. The swept signal may be triggered, gated, single stepped or swept-and-held. Main Generator frequency may be swept as much as 1000:1.
