E8247C PSG CW Signal Generator
Providing premium performance at an affordable price, the E8247C PSG CW signal generator delivers industry-leading output power, superior level accuracy, and low phase noise for local oscillator and low jitter clock substitution and interference signal generation.
It typically eliminates the need of an external amplifier for testing high power devices and minimizes test uncertainty to identify errors early in the design process and reduce development time. The PSG features advanced capability, including ramp sweep for continuous sweep measurements and fully automated use with the Keysight 8757D scalar network analyzer.
E8257C PSG Analog Signal Generator
Providing premium performance at an affordable price, the E8257C PSG analog signal generator delivers industry-leading output power, superior level accuracy, low phase noise, and precision analog modulation for accurate characterization of RF and microwave components and devices.
The PSG sets a new price performance mark by providing advanced capabilities; including narrow pulses for radar test applications and ramp sweep for continuous sweep measurements and fully automated use with the Keysight 8757D scalar network analyzer.
E8267C PSG Vector Signal Generator
Keysight's E8267C PSG vector signal generator is the industry's first integrated microwave vector signal generator with direct I/Q modulation up to 20 GHz. It features a built-in wideband I/Q modulator that delivers up to 1 GHz RF modulation bandwidth and an advanced wideband (80 MHz) internal baseband generator capable of flexible arbitrary waveform playback and sophisticated real-time signal generation. Clearly this groundbreaking integrated functionality, only available in the E8267C PSG, drastically simplifies the generation of complex vector modulated signals for design and manufacturing test applications in aerospace, defense, satellite communications, and broadband wireless.
Just imagine, convenient access to the most complete set of calibrated wideband test stimuli ranging from digital and analog baseband to RF and microwave carrier frequencies.
