Product Description

The Tektronix 3086 Real-time Spectrum Analyzer is a wide band, very sensitive receiver. It works on the principle of "super-heterodyne receiver" to convert higher frequencies (normally ranging up to several 10s of GHz) to measurable quantities. The received frequency spectrum is slowly swept through a range of pre-selected frequencies, converting the selected frequency to a measurable DC level (usually logarithmic scale), and displaying the same on the CRT of the Tektronix 3086. The CRT displays received signal strength (y-axis) against frequency ( x-axis).

The Tektronix 3086 is a DC to 3 GHz real-time spectrum analyzer that allows the seamless capture of frequency spectra with spans up to 30 MHz (5 MHz - 3066). This allows the spectrum of burst signals, such as those from GSM, IS-136, PDC or partial rate CDMA mobile stations, to be easily captured and examined. Real-time spectrum analyzers take a very different approach compared to traditional sweeping spectrum analyzers. Rather than acquiring one frequency step at a time, the real-time instrument captures a block of frequencies all at once. Because the instrument samples these full frames constantly (rather than waiting for each discrete frequency step to be measured), the signal can come or go as it pleases and the real-time spectrum analyzer will detect the change instantly.

The 12.1 in. color TFT display allows easy viewing of spectrum, waterfall displays, spectrograms and digital modulation analysis screens. Constellation and vector diagrams can be displayed, as well as frequency, phase, magnitude, I and Q versus time, for in-depth analysis of digitally modulated signals. Users can move a marker through the time record and analyze the modulation at any point. In particular, signals with symbol rates up to 20.48 Msymbols/sec (3066 - 5.3 Msymbols/sec) may be analyzed during and after capture. This facilitates analysis of W-CDMA signals with chip rates up to 16.384 Mcps.
