INTRODUCTION The Wavetek Modeis 3003 through 3006 are rugged, completely solid-state Signal Generators covering the frequency range of .001 or 1 to 520 MHz. Models 3004 and 3006 cover the range of .001 to 520 MHz while Modeis 3003 and 3005 cover the 1 to 520 MHz range. Modeis 3005 and 3006 offer 100 Hz resolution while on Models 3003 and 3004 the resolution is 1 kHz. The output can be amplitude or frequency modulated and the level can be set between +13 and -137 dBm. 1.1.1 FREQUENCY CHARACTERISTICS The frequency of the instrument is set via 6 or 7 front-panel Lever/Indicator switches which yield a resolution of 1 kHz or 100 Hz. In addition, remote programmers are available to facilitate semi-automatic programming of frequency and GPiB programming of both frequency and output level. The accuracy of the instrument is based on a crystal-controlled Oscillator that serves as a stable frequency reference that enables the instrument to provide high-stability signals to an accuracy of 0.001% over its specified frequency range. This accuracy includes possible errors due to short-term drift, long-term drift, incidental FM, and variations due to line voltage changes and temperature changes. With the FREQUENCY VERNIER out of the CAL position, the frequency is accurate to 0.001% ±10 k Hz. The accuracy of the instrument can be Improved by using either the optional External Reference input, or the optional High Stability internal Reference. An Auxiliary RF output option is also available to drive a Counter. Refer to Section 1.3 for a listing of options available for each instrument. 1.1.2 MODULATION These instruments also feature both internal and external AM and FM capabilities. The internal and external sources can operate independently, or may be used simultaneously to produce complex modulation. Internal modulation frequencies include 400 Hz, 1000 Hz, and two preset frequencies between 100 Hz and 10 kHz, selected by the user. Modulation is indicated on a front-panel meter calibrated for full-scale readings of 30% and 100% AM, and 3, 10, 30, and 100 kHz deviation for FM operation. 1.1.3 OUTPUT LEVEL FEATURES The output power is indicated on a front-panel meter calibrated in both dBm and VRMS, A fifteen-position, 10 dB/ step Attenuator used in conjunction with an 11 dB VERNIER control provides the user with a range of +13 dBm to -137 dBm. A Programmable Attenuator option is available covering the range of from 0 to 109.9 dB attenuation in .1 dB steps with +13 dBm as the 0 dB reference level. The calibrated output of the Instrument is leveled to within ±0.75 dB across the complete frequency range of the instrument. Reverse power protection is also available as an option.
