Informazioni
The Model 8601A Generator weeper is a rf signal source with both CW and wide band swept frequency capabilities in the 0.1 to 110 MHz range. In the CW mode, residual fm is less than 50 Hz rms from 0.1 to 11 MHz, and less than 500 Hz rms from 1.0 to 110 MHz (including line-related components). Harmonic outputs are 35 dB below the carrier; spurious and non-harmonic outputs are 40 dB below the carrier. Swept-frequency measurements of all or any part of the 0.1 to 11 MHz or 1.0 to 110 MHz bands are possible by selection of FULL, VIDEO, or SYMMETRICAL sweep modes. Internal and external frequency modulation is also possible for narrow-band sweep operations or remote tuning.
The FULL sweep covers the whole 0.1 to 11 MHz or 1.0 to 110 MHz band. The VIDEO sweep is from the bottom of the selected range up to the frequency selected by front panel frequency control. The SYMMETRICAL sweep operation sweeps above and below the CW frequency selected by front panel frequency control. The symmetrical sweep width is calibrated from 0.01 to 1.0 MHz for the 0.1 to 11 MHz band, and from 0.1 to 10 MHz for the 1.0 to 110 MHz band. A sweep width vernier adjusts the sweep width from the calibrated position to zero.
The calibrated rf output is variable from +20 to -110 dBm (2.23V to 1 µVrms) into 50 ohms by use of the OUTPUT LEVEL and VERNIER controls. Other outputs include a 0.1 to 11 MHz auxiliary output on both bands to permit use of a low Frequency counter for frequency monitoring; a 0 to +7V sweep output for horizontal drive of Oscilloscope and X-Y recoders; and an uncalibrated rf output for phase-lock operations.
