Operation
The B+K Precision Model 4011A Function Generator is a versatile instrument capable of producing various output waveforms over a broad range of frequencies. To gain familiarity with the unit, it is recommended to connect it initially to an oscilloscope to observe the effects of the various controls on the output waveforms. The manual should be used as a reference until the user becomes accustomed to the operating procedures.
For frequency and waveform selection, initially verify that the DUTY CYCLE, CMOS LEVEL, DC OFFSET, and -20dB switches are in the OUT position to produce a symmetrical waveform unaffected by other controls. Plug the unit into an appropriate power source and turn it on using the POWER switch. Select the desired waveform (SINE, SQUARE, or TRIANGLE) by engaging one of the function switches.
