The HP 83752B synthesized sweeper provides superior accuracy and stability while maintaining the speed of analog sources. Fully synthesized CW, stepped, and ramp sweep modes are available in broadband and narrowband operation. The synthesis capabilities are particularly useful for the characterization of narrowband devices, in which the frequency instabilities of open-loop sources become most apparent. Excellent output power flatness and accuracy can be translated to the input port of the device under test with the power flatness correction feature of these sources. This feature uses a power meter to create an array of power corrections that cnmpensate for power variations in the measurement path between the source and the test device. Swept testing of frequency translation devices can be achieved simply and economically with the HP 83572B synthesized sweeper. A traditionally difficult measurement, sweeping the RF and local oscillator (LO) input ports at a fixed offset over a wide frequency span, is easy to implement with superior frequency accuracy by positioning two synchronously tracking HP 83752B's in a two-tone configuration. With broadband frequency coverage and excellent performance, the HP 83752B synthesized sweeper is ideal stimuli for frequency translation measurements. Specifications. Frequency Range: 0.01 to 20 GHz. Maximum Leveled Power: 16 dBm < 2 GHz. Minimum Settable Power: - 10 dBm ( - 85 dBm w/Opt 1E1). Resolution: 0.01 dB settable. Accuracy: ±1.5 dB (levels> - 75 dBm). Flatness: ± 1.3 dB (levels> - 75 dBm). Power Sweep Range: 25 dB/sweep. Power Slope Range: 0 to ±2 dB/GHz, 25 dB max. Source Match (typical) : < 1.7:1 SWR. Harmonics: - 20 dBc. Bandwidth Points: 2 GHz, 3.75 GHz, 6.75 GHz, and 11 GHz. The 3.75 and 6.75 GHz synthesizer switch will disappear if sweep is <0.8 of an octave in the 2 to 11 GHz band. Options. Opt 1E1: 70 dB Step Attenuator. Opt 1E4: Rear Panel RF Output. Opt 1E5: High Stability Time Base. Opt 1ED: Type-N Connector Output.
