3026

The Sony/Tektronix 3026 is a portable real time spectrum analyzer with a frequency range of 10 MHz to 3 GHz. The incorporated 3 GHz down converter enables performing spectrum analysis, time domain analysis, and analog modulation analysis of Radio Frequency (RF) signals without connecting any external devices.

The 3026, with the adoption of new architecture, can acquire time and frequency domain data simultaneously. It can also capture various kinds of signals with a wide variety of triggering functions.

Real-time trigger functions in frequency domain allow you to trigger on instantaneous events such as the starting point of a burst signal. Trigger functions include Mask pattern trigger, Level trigger, and External trigger. Using the trigger functions in time domain, triggering is available on impulse noises which are barely captured in frequency domain.

In addition, the 3026 provides measurement functions that can evaluate the performance of radio devices with simple operation. Moreover, four types of data display functions offered in the system (Spectrum, Spectrogram, Waterfall, and Analog demodulation of AM, PM, FM, and FSK) allows analysis of the acquired data more precisely.

Waveforms and measurements are displayed on the 6.5 inch full-color (640 x 480) TFT display. 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; IEEE STD 488 PORT GPIB interface; VGA OUTPUT female DB15; 10 BASE-T Ethernet; 10 MHz REF OUTPUT BNC connector; and 10 MHz REF INPUT BNC connector.
