3026 – Tektronix Spectrum Analyzers
3.00GHz (High end frequency limit)
The Tektronix 3026 offers a full 2 MHz of real-time bandwidth with measurement speed of 25,000 frames/second and a 1024 point update interval of 160 microseconds. The captured events can be conveniently displayed in a variety of formats selectable by the user: Spectrum, Spectrogram and Waterfall. The analyzer architecture makes it possible to capture time domain data and frequency domain data simultaneously.
To catch instantaneous phenomenon like a transmitter startup, or the beginning of a digital TDMA or CDMA transmission, the 3026 provides frequency domain and time domain real-time triggering with a mask pattern that is easily edited in the built-in editor.
The 3026 consists of a 3 GHz down converter unit which converts the RF signal to IF, the A/D converter which converts analog signals to digital, the digital down converter (DDC) which down-converts the center frequency and changes the span, the real-time FIFO which frames the data stream, the FFT processor which extracts the spectrum components, a memory system which captures the time and frequency domain data, and the system controller which covers the user interface and hardware control.
The system architecture is based on the ISA bus. The instrument software operates under the VxWorks. Instrument controls and functions are implemented in C language. The display is a 6.5 in. VGA TFT-LCD. The 3026 includes a 3.5 in. floppy disk unit and 1.5 GB hard disk drive. GPIB and Ethernet interface are standard along with a parallel printer port.
