Microwave Signal Generator Shatters 1-W Barrier

Said to be the first microwave signal generator to break the 1-W output barrier, the PSG E8257D option 521 delivers from +24 to +28 dBm specified output power over a bandwidth of 250 MHz to 20 GHz (useable down to 10 MHz). A common limitation for virtually all microwave signal generators is a specified output power limited to less than +25 dBm, according to the company. Applications needing more power require extra hardware such as amplifiers, couplers, and detectors. The PSG with option 521 eliminates this equipment and its cost. With a typical maximum unleveled output power exceeding 1 W (greater than +30 dBm) over a large portion of the frequency range, users and units under test can be protected from high-power accidents with a new, adjustable rf output hardware power clamp. Able to be set from +15 dBm to +33 dBm at the output of the PSG, the adjustable power clamp works with internal and external leveling configurations. For higher-power, narrow frequency range applications, the maximum rf output clamp setting of +33 dBm provides access to option 521's maximum available unleveled output power. The PSG E8257D option 521 costs $41,575. AGILENT TECHNOLOGIES INC., Santa Clara, CA. (800) 829-4444.
