3086

The Sony/Tektronix 3086 is a portable real time spectrum analyzer with a frequency range of 10 MHz to 3 GHz. This spectrum analyzer is equipped with a 3 GHz down converter for analyzing radio frequency (RF) signals and allows seamless capture of frequency spectra with spans of up to 30 MHz. This allows the spectrum of burst signals, such as those from GSM, IS-136, PDC or partial rate CDMA mobile stations that are captured and examined.

The 3086 can obtain time domain and frequency domain data simultaneously through a new architecture which allows capturing a block of frequencies all at once. Because this 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.

A frequency mask trigger allows capture of randomly occurring or infrequent signals such as intermittent spurious emissions, as well as, the capture of “burst-on” periods, thus maximizing the number of bursts that can be captured in memory for subsequent spectral, time, or modulation analysis. The user can graphically define the frequency trigger mask; this allows the trigger condition to be generated by a particular event in the frequency domain.

Waveforms and measurements are displayed on the 12.1 inch full (256 max) colors (1024 x 768) TFT display which allows 1, 2, or 4 views 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 of any point. In particular, signals with symbol rates up to 20.48 Msymbols/sec may be analyzed during and after capture. This facilitates analysis of W-CDMA signals with chip rates up to 16.384 Mcps. Data is stored and retrieved from the built in hard drive (2.1 GB) and 3.5 inch floppy disk drive.

Front panel inputs/outputs are: RF INPUT 50Ω N connector; EXT TRIG BNC connector; and Floppy disk drive.

Rear panel inputs/outputs are: PRINTER female DB25 connector; SCSI female SCSI connector; 10 MHz REF OUTPUT BNC connector; 10 MHz REF INPUT BNC connector; I INPUT BNC connector; and Q INPUT BNC connector.
