  • Annotazioni
  • The HP-Model 610B Signal Generator provides a general purpose laboratory standard for measurements between 450 and 1200 Mc. It supplies an accurately known voltage throughout this range, from 0.1 microvolt to 0.1 volt. Output voltage and frequency are directly selected and read without reference to calibration charts.
    The 610B includes a high-frequency oscillator and an attenuator for accurately controlling output beyond a measured level. Also included is an internal pulser and modulator, and a regulated power supply to provide oscillator plate voltage. The oscillator employed is of the concentric type, utilizing a "lighthouse" tube, and is adjusted by the positioning of the shorting plungers in the concentric lines. Output voltage is derived through a mutual inductance type attenuator, coupled to the oscillator cavity. R-f voltage at attenuator input is measured by a thermistor bolometer.
    Internal pulsing circuits provide rectangular, r-f pulsed output of variable lengths and repetition rates. The pulse rate may be synchronized from an outside source. An external synchronizing pulse is provided. R-f signal may also be externally amplitude modulated.

    Specification
    Frequency Range: 450-1200 Mc directly calibrated.
    Attenuator: Mutual inductance piston type, directly calibrated in dB below 0.1 volts in 50 ohms; 120 dB maximum attenuation.
    Output: Accurately known voltages from 0.1 microvolt to 0.1 volt supplied through 50-ohm coaxial cable terminated in type "N" connector. Internal impedance 50 ohms. Accuracy better than ±1 dB over entire range.
    Modulation: Internal pulse, external pulse, external square wave, external amplitude.
    Internal Pulser: Pulse length variable 2 to 50 microseconds. Repetition rate variable 60 to 3000 cps. Pulse delay variable 3 to 300 microseconds (between externally supplied synchronizing pulse and beginning of r-f pulse).
    Leakage: Sufficiently low to permit measurement of sensitivities as low as 1 microvolt.
