Advantest TR4171

Advantest TR4171 Spectrum Analyzer.

This 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 this unit.

The CRT displays received signal strength (y-axis) against frequency ( x-axis).

Specifications:
Dynamic Range: -999dBm
Frequency range: 10Hz to 120MHz
