a. For frequency coverage beyond 70 GHz, utilize millimeter-wave multiplier 2000-1694 series (see page b. Operational to 70 GHz c. All specifications apply ≥ 10 MHz

Options 4 and 5 Frequency extension down to 8 MHz

Two options are available to extend the 2 GHz low end frequency limit of the base models down to 8 MHz. Option 4 uses a digital down-converter (DDC) with successive divide-by-two circuitry. It offers the best phase noise performance of the two choices, at the expense of some analog performance < 500 MHz. In that range, analog sweep mode is not available, and pulse modulation performance is specified as typical. In addition, frequency and phase modulation mod index is scaled by the division ratio of each band of the DDC. Option 5 maintains all analog performance by using a heterodyne mixing down-converter, but does not improve phase noise performance.

Option 22 If frequency coverage down to 0.1 Hz is desired, Option 22 can be added with either Option 4 or 5.

Option 22 uses Direct Digital Synthesis (DDS) for CW and Step Sweep modes of operation. Modulation and analog sweep are not available in the DDS band. Frequency resolution < 10 MHz is 0.02 Hz. Output power across the complete instrument frequency range is degraded by 2 dB.
