Performance backed by Agilent’s reputation and manufacturing experience Production margin Every Agilent Technologies’ signal generator meets specifications that would reject most other signal generators Before any Agilent Technologies’ signal generator is introduced, specifications are set to assure that the product will perform consistently for your application. The specification setting process is reflective of the quality that Agilent has always strived to deliver.
-60 -120 Option 004 -140 -160 10 RF leakage Due to radios becoming more sensitive and operating at higher frequencies, the traditional two-turn loop measurement of RF leakage has become inadequate. To overcome the shortcomings of the twoturn loop, Agilent has developed a new measurement technique using resonant dipole antennas, which is 20-25 dB more sensitive than the two-turn loop method.
Features that improve the usability of Agilent’s 8643A, 8644B, 8664A and 8665A/B for your application! Internal modulation source • Low distortion sinewaves to 400 kHz with variable phase and amplitude. • Triangle, sawtooth and squarewaves to 50 kHz with variable phase and amplitude. • White Gaussian noise with variable amplitude. • Two independent sources for two-tone testing.
Wideband FM (8664A and 8665A/B) Performance signal generator series features 2 GHz frequency counter (Option 011, 8643A and 8644B) • Typical rates to 5 MHz with 2 MHz of deviation, or rates to 800 kHz with 10 MHz of deviation (fc >1500 MHz) allows testing of most wideband receivers. • Excellent FM linearity is inherent due to YIG oscillator design. • Stable dc-coupled FM for measurements that require low carrier drift. • High stability oven controlled timebase is standard.
