Jameco Part Number 20685
(JE2206)
Function Generator Kit
GENERAL DESCRIPTION
The 20685 (JE2206 Function Generator Kit) is a
single-board assembly incorporating the basic
circuit necessary for a sine, square, and triangle
wave generator, of high stability and accuracy that
may be amplitude and frequenc
k
it is intended to be incorporated into a higher
as
sembly of the user's own design that adds power
sup
ply controls, and housing.
,
Operati
ng from either a +12VDC or +/-
6VDC @ 15mA power source
Freque
ncy capability: +1 to 100KHz in 4
ranges
Frequency variability: 1:100 within each
range
• Frequency accuracy dependent upon
timing capacitors and user's potentiome
(calibration by user)
• Sine / triangle output amplitudes variable,
0 to 6Vp-p for sine and 0V to V
triangle, with 600Ω source impedance
Maximum sine wave distortion: 1% 10
10kHz; and 3% 10 to 100kHz
Linear freque
ncy modulation capability
range dependent on center frequency
Linear amplitude modu
range
55dB
