Portable Laboratory Performance with Affordable Prices
Tektronix 490 Series Spectrum Analyzers offer a broad selection of features and benefits to meet wlde-ranging needs for laboratory-level frequency domaln spectrum analysis. All units provide full IEEE-488 (GPIB) programmability, which means you can change front panel settings, read data from the crt display, and send waveforms from internal digital source memory to other GPIB devices. Frequency range of the instruments is as follows:
Built to rugged MILT28800C environmental specifications, these units can withstand transportation shock and vibration to a remote slte. Or they can simply be moved from the engineering lab to the production floor with complete confidence in measurement accuracy.
A wide array of price/performance alternatives are available. If you need 10 Hz resolution for an exacting close-in spectral purity measurement, consider the 494AP For more routine uses, such as a microwave transmitter occupied-bandwidth measurement, the 492PGM may be the most cost-effective solution.
A Wide Array of Intelligent Features:
Downloadable programming (macro) capability lets you execute your frequently-used measurement routines from the Spectrum Analyzer's nonvolatile memory. In addition, these Spectrum Analyzers can store up to 10 complete front-panel measurement parameter setups in nonvolatile memory to save you measurement time. You can also save up to 9 waveform display; a real benefit when data analysis must be delayed.
Tedious, time consuming, and often incorrect carrier-to-noise ratio calculations are eliminated; the instrument handles it all with a single keystroke, with automatic noise normalization to 1 Hz and automatic conversion for reference units such as dBm, dBmV, dBV, dB& and dB/Hz.
An internal high-stability reference provides marker or center frequency accuracy approaching 10 -9/day in the 494AP. For added confidence in measurements, a built-in microwave signal counter in the 494AP with 144 dB dynamic
