Information

The Wavetek Models 1080.1081 are economical, laboratory* quality, wide-band sweep generators designed to meet the needs of engineering, production, maintenance, and educational facilities. The major features of these instruments include the wide frequency range (1 to 1000 MHz), the ability to sweep over any portion ot the frequency range, digita! frequency and output level readouts, and display linearity of 1%. Operating modes include CW, Af, and FS {full sweep). A unique "auto-zero" circuit virtually eliminates annoying frequency drift normally associated with wide-band sweep generators, and provides for superior narrow-band operation and improved frequency accuracy. A crystal-marker circuit provides markers at 1, 10, and 100 MHz harmonic intervals (with different amplitudes for positive identification of the interval points) throughout the entire frequency band. Marker width is adjustable from the front panel for optimum wide- and narrow-band operation. An external marker input is provided on the front pane!. A calibrated variable "pinball" marker is also provided in the full sweep mode. The rear-panel SLOPE control allows up to 1 dB/GHz (.1 dB/100 MHz) of slope (1 MHz pivot point) to be imposed on the output to compensate for frequency- dependent variations in the external circuitry. The instrument's center frequency, sweep width, and output level can also be remotely controlled via a rear-panel connector. This connector also provides access to the blanking, 1 V/100 MHz, sweep ramp, pen lift, and ±18 V Power Supply output signals, as well as providing a connection for an external trigger input. These instruments feature modular PC board Plug-In construction for all non-RF circuitry. The RF circuitry is contained in its own shielded assembly. This concept offers protection against obsoSesence, since updated and additional features can be simply and economically added as new requirements dictate. In addition, maintenance problems can be greatly simplified by stocking a few assemblies instead of hundreds of discrete components.
