The Tektronix 492 and 496 are two spectrum analyzers that go where you go. Their compact size, light weight, and rugged design combine to offer unmatched portability in laboratory quality analyzers. Single-handle carry and portable form factor make them ready to travel. The 492 and 496 move as easily in the field as in the design lab or systems test area. They even fit under an airplane seat. You can count on the same exceptional performance no matter where you're working. If its antenna test measurements, point-topoint transmission maintenance, or any number of critical field applications, the 492 and 496 work with you. For on-site applications, reduced warmup time means reduced measurement time. Typical long-term frequency drift of 5 kHz/10 minutes after 30 minute warm up for the 492 and 492P; 2 kHz/10 minutes after 30 minute warm up for the 496 and 496P. Here's Proof of Their Performance The Tektronix 492 has the widest amplitude calibrated frequency range of any spectrum analyzer on the market: 50 kHz to 220 GHz —to 21 GHz in coax, from 18 GHz to 220 GHz using Tektronix external waveguide mixers. The VHF/UHF 496 covers from 1 kHz to 1.8 GHz. They offer 80 dB dynamic range on-screen and excellent sensitivity, with an average noise level of — 123dBm at 100 Hz resolution bandwidth for the 492, -127 dBm at 30 Hz resolution bandwidth for the 496. Low phase noise —70 dBc at only 3 kHz offset —for accurate small-signal analysis. High stability for signal source spectral purity analysis, with residual FM of no more than 50 Hz peak-to-peak for the 492, 10 Hz peakto- peak for the 496. For precise measurement of signal differences, there's amplitude comparison in super-fine 0.25 dB steps. And the 496 provides 1 kHz frequency resolution in AF mode. All this and more in one compact package that goes where you go. Programmability/IEEE (GPIB) Compatibility The GPIB interface enables full control of all measurement settings. Additional control of horizontal (span) and vertical display (1 dB to 15 dB/div) and smart functions (such as signal search) provide added measurement versatility. A desktop computer or computer controller (4052A or 4041) and a 492P or 496P Spectrum Analyzer provide repetitive measurements, data collection, and consistent, rapid results. Automated testing and monitoring may include data correction and analysis enabling complex measurements such as total harmonic distortion and power spectral density. The thermal printer of the 4041 or hard copiers for 4052A simplify documenting tests and spectral displays in hard copy form. Programmability Now—or Later Most manual 490 Series spectrum analyzers can be converted into fully programmable, GPIB compatible analyzers. Conversion may be performed via the Tektronix Service Center near you. Easy to Use—Anywhere Tektronix designed the 492 and 496 to handle your measurement task with microprocessor- aided ease. Setting frequency, span and reference level is a simple three-knob operation. Most-used functions are automatically controlled. Digital storage and signal processing eliminate time-consuming display adjustments. And constant tuning rate helps you position a signal quickly and accurately. All part of the convenience and capability the 492 and 496 deliver, on site or on the bench.
