Tektronix 492-02-03

Base Frequency: 50 KHz Max Frequency: 21 GHz

The 492 Portable Spectrum Analyzer is a high performance, rugged, microprocessor aided instrument of compact size and offers automatic modes. Three-knob operation provides use as simple as 1, 2, 3 through microprocessor coupled functions such as resolution bandwidth, video bandwidth, sweep time, frequency span, RF attenuation, and reference level. This portable spectrum analyzer covers from 50kHz to 21GHz (to 220GHz with optional waveguide mixers, sold separately). Offers fully calibrated amplitude and frequency along with CRT readout of all important parameters for operator convenience and quick setups. Amplitude comparison in 0.25 dB steps. Dynamic range of 80 dB. The instrument has a resolution bandwidth of 1MHz to 1kHz in decade steps, plus an autoposition. Resolution is within 20% of selected bandwidth.

Options:
Option 02 = Digital Storage. With Save A, maximum hold, B minus Save A, display averaging, and storage bypass
Option 03 = Frequency Stabilization 100Hz Resolution. Provides first local oscillator stabilization by phase locking the oscillator to an internal reference.
