OPERATING INSTRUCTIONS
10
The B+K Precision Model 4010A Function Generator is a
versatile instrument, capable of producing a variety of output
waveforms over a broad range of frequencies. To gain a working
familiarity with the unit, it is recommended that it be connected
initially to an oscilloscope, so that the effects of the various
controls on the output waveforms can be observed. Use this
manual as required for reference until becoming accustomed to
the operating procedures.
FREQUENCY AND WAVEFORM SELECTION
l. Initially, verify that the DUTY CYCLE (14), CMOS
LEVEL (13), DC OFFSET (12), -20dB (11) switches are
in the OUT position (released). This will produce a
symmetrical waveform unaffected by the other controls.
2. Plug the unit into an appropriate power source and turn it on
by engaging the POWER switch (1).
3. Select the desired waveform (SINE, SQUARE, or
TRIANGLE) by engaging one of the FUNCTION switches
(3). Phase relationships of the waveforms are shown in Fig.
2.
4. Select the frequency of the waveform by engaging one of
the RANGE switches (2).
5. Rotate the FREQUENCY control (15) to set the output
frequency to the desired value. The frequency selected is
available at the OUTPUT jack (6). In addition, a digital
signal, either TTL or CMOS is available at the TTL/CMOS
jack (7) (refer to the “TTL/CMOS OUTPUT” section of this
manual).

Relationship
6. Adjust the amplitude of the output as desired using the
OUTPUT LEVEL control (4). Rotation of this control
varies the amplitude from maximum to 20 dB below
maximum. An additional attenuation of -20 dB is
available by pushing in the -20dB switch (11). The
attenuation factors can be combined for a total of -40
dB. The maximum signal level is 10 V p-p (into 50 Ω).
