Information

The Wavetek Models 1403 and 1503 are all-solid-state, electronically swept and tuned Sweep Generators covering the 1 to 300 MHz and 450 to 950 MHz frequency ranges. They are designed especially for testing and aligning television tuners and receivers. The Mode! 1403 covers the VHF (1 to 300 MHz) range while the Model 1503 covers the UHF (450 to 950 MHz) range. An important feature of these instruments is their ability to be remotely controlled and programmed. This enables the sweep generator to be sequenced through the test procedure with pushbutton switches or electronic sequencers, instead of manual tuning and adjustments. The instrument's most outstanding options are those of automatic operation. Simply stated, in automatic operation, the sweep generator's frequency and RF output level are automatically adjusted to follow the variations of the tuner. This provides considerable time saving during the alignment procedure. Included with the automatic options are scope indicators that provide both frequency and RF output indications directly on the oscilloscope tube. Additional options include up to eight crystal-controlled RF markers (either single frequency or harmonic type) and local oscillator tracking markers. By the use of a special combining cable, Models 1403 and 1503 may be operated as a combination unit providing independent frequency and output amplitude controls with a single set of scope horizontal and vertical cables. When operated as an automatic instrument, one set of local oscillator tracking markers, automatic level, and automatic frequency options provides control of both instruments. All optional features, as well as the circuits for the basic sweep generator, have plug-in modular construction. This allows optional features to be factory-installed at the time of purchase, or customer-installed at a later date. This concept offers protection against obsolescence, since updated and additional features can be simply and economically added as new tuner designs and test procedures dictate. Maintenance problems can be greatly simplified by the stocking of several modules instead of hundreds of discrete parts. Servicing time of a defective instrument can be cut to a fraction of the time previously required, and can be performed by relatively inexperienced technicians.
