The BK Precision 4003A 4 MHz Sweep Function Generator has a sweep function that offers linear or log sweep with variable sweep rates and widths. The BK4003A also has the addition of a 20 MHz 5 digit, Red LED, external frequency counter. The function generator generates sinusoidal, triangular, ramp, square, and pulse waveforms. The type of function is selectable through a rotary switch. The frequency is settable from 0.5 Hz to 4 MHz of the function with range selector switch and the frequency control knob for variable adjustments with multiplication factor of 0.04 to 4.0 of the selected frequency range. The signal amplitude can be adjusted from 0.2 V to 20 Vpp with no load conditions and 0.1 V to 10 Vpp with a 50 ohm load termination. The MAIN output has the provision of SYNC output signal (TTL level) when selected. The sweep generator offers linear or log sweep with variable sweep rate and adjustable sweep width.
Auto ranging, 5-digit frequency counter is provided with range from 0.2 Hz to 20 MHz and resolution of 0.01 Hz. The counter is utilized for external as well as internal functions. In addition to the features above, an external voltage signal can be used to control the frequency of the function. With AC input signal, FM output can be generated.
