GENERAL CAPABILITIES The Model 146 Multifunction Generator consists of two independent signal sources in one integrated unit. Each generator can be used as an individual signal source, or both can be used together. Functions and operating modes of both generators are push button selectable. The signal of the main generator can be frequency or amplitude modulated by any of the auxiliary generator waveforms. Analog control of output frequency and amplitude is provided by VCG {Voltage Controlled Generator) and VCA {Voltage Control of Amplitude) circuitry. Amplitude is variable from maximum through null to maximum at inverted phase. A caliper dial establishes upper and lower limits for frequency and amplitude modulation. Continuous, triggered and gated waveforms can be produced by the main generator through the range of 0.0005 Hz to 10 MHz. The auxiliary generator is capable of producing sine, square, triangle, and special sawtooth outputs. These waveforms can be internally applied to the main generator to obtain frequency modulation and frequency sweep up to 1000:1 ratio; amplitude modulation through 100% to suppressed carrier modulation; and triggered, gated and tone burst outputs. Operating range of the auxiliary generator is 0.004 Hz to 100 kHz. Both generators can be externally triggered. VCG and VCA connectors are available for external inputs to the main generator. Auxiliary and main generator output impedances are 60012 and 5012, respectively.
