  The Agilent/HP 8656A 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 Agilent/HP 8656A 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. Features 100 kHz to 990 MHz frequency coverage <35 ms frequency switching speed AM and FM capabilities ±1 dB level accuracy Amplitude offset and phase adjust capabilities Low RF leakage eliminates measurement interference Sensitivity measurements can often be masked by RF leakage (radiated emissions). With the 8657A and B, RF leakage is reduced to a level that assures virtually no measurement interference. DCFM faithfully reproduces digital signals For radios with digital squelching, the 8657A and B have extremely stable dc-coupled FM (dcFM). The dc coupling of low-rate tones or digital data eliminates droop, and the exceptional stability and center-frequency accuracy when in dcFM mode eliminates the need to retune the signal generator after dcFM is selected. Pulse modulation with the 8657B High-performance pulse modulation (available on the 8657B) will give you confidence in your radar or pulsed carrier measurements. This includes rise/fall times of <35 ns, rates from dc to 30 MHz, and better than 70 dB on/off ratios (fc<1030 MHz).  

Features

  • 100 kHz to 990 MHz frequency coverage
  • <35 ms frequency switching speed
  • AM and FM capabilities
  • ±1 dB level accuracy
  • Amplitude offset and phase adjust capabilities

Precise Output Control

  The Agilent/HP 8656A provides a ± 1.0 dB absolute level accuracy and 0.1 dB resolution with calibrated power levels over +13 to -127 dBm.  The output level can be offset to compensate for losses external to the generator.  RF leakage is well-shielded at < 1.0 mV and 25 Ù  reverse power protection guards against accidental damage.

Versatile Modulation

   The Agilent/HP 8656A is capable of simultaneous AM and FM modulation.  The instrument provides internal 1 kHz and 400 Hz sources and also accepts external sources.  AM is ac-coupled, while FM can be either ac- or dc-coupled.  The dc-coupling is exceptionally stable (< 10 Hz/hour drift) and accurate (± 500 Hz center frequency accuracy).
