HP 8656B
Signal Generator, 100kHz-990MHz
The HP 8656B is a programmable
synthesized signal generator that combines performance, quality, and economy,
covering the 0.1 to 990 MHz frequency range. Offering ±1 dB level accuracy
and 0.1 dB resolution with calibrated output levels over the +13 to -127
dBm range, the HP 8656B provides
precise output control. In addition, its modulation capabilities include
simultaneous and mixed modulation modes from internal (400 Hz and 1 KHz
tones) and external sources. These features create a versatile signal
generator, for use in a variety if applications.
