Agilent HP 3320B,6,7H17

The 3320A/B frequency synthesizer offers a broad frequency range of 0.01 Hz to 13 MHz, low spurious content, and low signal-to-phase noise. It is capable of one part in 10⁶ frequency resolution across the entire frequency range.

The 3320B is a precision programmable bench signal source—more than a synthesizer—because it provides precise level control, excellent frequency response, high power output, low harmonic distortion, and the flexibility of two choices of digital remote control. It features a four-digit leveling loop with a 0.01 dB level resolution of a calibrated output from +26.99 dBm to -69.99 dBm. Frequency response of ±0.05 dB over the range of 10 Hz to 13 MHz, and level accuracy of ±0.05 dBm absolute at 10 kHz complement the level capability of the 3320B.
