SWEEP/SIGNAL GENERATOR

Information

The Wavetek Model 1801A Sweep/Signal Generator provides features and options ideally suited for the manufacturer, installers, and operators of CATV systems. The frequency range of from 1 to 500 MHz, or,with the high band, of from 1 to 950 MHz, adequately covers the frequency bands now being used as well as those of „the future. The instrument will sweep each band in It's entirety, or sweep width may be continuously reduced to CW operation. The Ultra flat 75 ohm output system ' is calibrated from +57dBmV to -33 dBmV* 20dB of the total attenuation is a continously variable electronic attenuator diode). A three position reference switch, in parallel with this attenuator, will increase or decrease the output by +0.5dB. (An internal calibration allows the reference to be set at any level fro^ +0dB to +0.5dB). This greatly aids in flatness measurements by providing an accurate rapid calibration reference. Other features include Built-In RF Detector, External Leveling Circuitry, and a complete Crystal-Controlled Birdy Marker System which may be used to internally modulate the RF signal. A selection of marker widths for wide band or narrow band operation is also provided. The instrument will sweep at Line frequency, 60 Hz, or as slow as 1 sweep in 100 seconds. A special sweep rate position facilitates faster testing of operating CATV systems with minimum subscriber interference. The sweep time of this position is adjustable from 1 to 10 milliseconds and the repetition rate is adjustable from 1 to 10 seconds. The Model 1801A uses modular construction for ease of maintenance and modifications. All standard options , can be either factory or field installed. The small, compact, all solid-state instrument is 5-1/4" X 8" X 13” and weighs only 20 pounds.
