Used TEKTRONIX 191 #9117996 for sale

TEKTRONIX 191 is a fast, versatile four-quadrant, low-level frequency domain analyzer and digitizer. It combines the speed and accuracy of traditional domain analysis techniques with TEKTRONIX unique digital signal processing, giving the user comprehensive low-level frequency analysis capabilities. 191 features key characteristics like: a high-bandwidth capability with a frequency range of up to 10 MHz; a wide-viewing design for maximum display clarity; the ability to control multiple devices under test with remote control capability; and a high-precision phase margin indicator. TEKTRONIX 191 performance is based on the combination of powerful, custom electronics, from the low-noise preamplifiers to the precision analog comparators. Its frequency range extends from 10 Hz to 10 MHz, and it offers excellent signal-to-noise ratio. The wide-viewing design, coupled with the high-resolution, high-brightness display, facilitates observation of the dynamic signals and the excellent display of complex time-based waveforms. 191 is also designed to help users quickly analyze, identify and observe low-level frequencies while actively exercising the test fixture. Its unique signal-conditioning circuitry provides the user with the tool to determine the input sinusoidal components and their relative magnitudes. This is particularly useful when fault-finding or analyzing the performance of power supplies. TEKTRONIX 191 is also well suited for in-circuit testing operations. The signal conditioning can be set up so that the waveforms from the device under test can be accurately tested for accurate results. The four-quadrant analyzer, akin to a peak detection circuit, allows the user to quickly make analyzer and sensitivity measurements, giving the user greater control over where in the circuit the test should be made. Thanks to its unique combination of circuit utilizations, 191 is one of the most advanced and versatile test equipment available. Its speed, accuracy, reliability, and overall utility make it the perfect choice for both low-level frequency domain analysis and in-circuit testing operations.
