Agilent / HP 3336B

Description

Covering a frequency range of 10 Hz to 20.999 MHz, the 3336A(CCITT) and 3336B (Bell) Synthesizer/Level Generators have performance characteristics that make them ideally suited for the telecommunications industry. The 3336C is designed for traditional synthesizer applications as well as R&D and production testing of systems or components. All three feature precision level control, high spectral purity, optional frequency stability of t- 5 x 10-'/week, internal frequency sweep and numerous user conveniences. All models include HP-EB (IEEE Std. 488-1975) as a standard feature for use in automatic test systems.

Precision Frequency Measurements

Major advances in HP technology have provided a single loop, fractional-N synthesis technique which allows synthesizer accuracy with 11 digits of resolution, plus. . . completely phase continuous frequency sweep over any of the instrument's frequency ranges. Microhertz resolution below 100 kHz allows precise frequency measurements over a range of 10 Hz to 20.999 999 999 MHz. Harmonics are below 60 dB over the range from 50 Hz to 1 MHz (50 dB to 20 MHz), with spurious signals below 70 dBc or -100 dBm in the standard instrument, - 11 5 dBm with an option.

+/- 0.05 dB Amplitude Accuracy

New HP attenuator technology coupled with custom designs in leveling loops and thermal converters produce amplitude accuracies seen only in instruments at much greater cost. The fast leveling loop makes extremely flat sweeps possible at fast sweep speeds. External leveling is also available for those custom applications where a control loop is desired.
