Agilent Technologies has introduced a microwave signal generator with ultra high output power capability that breaks the one-watt output barrier. The Agilent PSG E8257D signal generator option 521 delivers from +24 to +28 dBm specified output power over a frequency range of 250 MHz to 20 GHz (useable down to 10 MHz) and eliminates the need for additional hardware such as amplifiers, couplers and detectors.
Andy Botka, vice president and general manager of Agilent's Signal Sources division says, "Our new microwave signal generator continues the tradition of accelerating innovation in RF and microwave test applications requirements for aerospace, defense and communications."
A common limitation for virtually all microwave signal generators is that specified output power is typically limited to less than +25 dBm. For applications that require specified output power higher than +25 dBm, such as TWT amplifier testing and ATE/antenna test configurations (where signal insertion loss is high due to switch routings and long cable lengths), extra hardware such as amplifiers, couplers and detectors are needed. The PSG with option 521 E8257D signal generator eliminates that requirement and the costs associated with that extra hardware.
With typical maximum unleveled output power exceeding one watt (greater than +30 dBm) over a large portion of the frequency range, users and UUT's (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 E8257D signal generator, 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 Agilent PSG E8257D signal generator option 521 is available now.
