RCA TYPE WR-50B RF SIGNAL GENERATOR Yes, This Vintage RCA RF Signal Generator is in Like New Condition. Very Minor Signs of Previous Use. Exellent Condition, Physically and Mechanically. Made by RCA/Electronic Instruments/ Harrison, N.J. 105 -130 Volts 50-60 Hz 15 Watts The RCA WR-50B RF Signal Generator is an all-purpose instrument, designed primarily for aligning and serving radio and television receivers. The generator produces tunable RF output from 85 kc to 40 Mc, 400 cps audio output and sweep output at 455 kc and 10.7 Mc. A crystal-controlled oscillator is also provided for use with an external crystal. The variable oscillator covers the fundamental frequencies from 85 kc to 40 Mc in 6 ranges. For higher frequencies, the second or third harmonic of the high range can be used. A vernier tuning control permits precise setting of the output frequency. The rf output can be modulated with the internal 400cps oscillator, or with an external audio signal. The modulation level is adjustable. A two-position attenuator switch, together with a varible attenuator control provide complete adjustment of the rf output level. Sweep output is provided at 455 kc and 10.7 Mc for sweep alignment of both am and fm if circuits. This sweep output makes it possible to obtain a continuous oscilloscope display of if handpass characteristics. A return-trace blanking circuit is included to provide a zero-reference line. The crystal oscillator circuit in the WR-50B enables the instrument to be used as a crystal calibrator. A convienent crystal socket is provided on the panel. This crystal oscillator can be used as a frequency calibration reference for the variable oscillator, or can be used directly as a crystal-controlled signal source. The generator includes a shielded rf output cable to minimize radiation and hum pick-up. A phono-type panel jack is provided for af input/output. The Wr-50B has brushed aluminum panel with permanently etched two-color dial scale and markings. The instrument is readily portable, weighing just five pounds, and measures only 4 3/4inches x 5 3/8 inches x 7 3/4 inches." (please look at our rules and privacy policy) |
