GENERAL DESCRITION
(5) POWER SUPPLY
The power supply circuit is powered by AC (1 OOV, 120V, 220V, 240V) and deliveres DC
±
22V sufficiently stabilized by large capacity smoothing capacitors and a voltage
stabilizer.
APPLICATIONS
• USE AS SINEW AVE OSCILLATOR
The AO- 3001 C can be used a sinewave oscillator as outlined below.
(1) The unit feature low distortion factor, it can be used for measurement of distortion
characteristic of amplifier.
(2) The unit features wide bandwidth, it can be used for measurement of characteristic of
amplifier
(3) Can be used as a signal source of impedance bridge.
(4) The built-in frequency counter direct read out internal frequency and can be used
external frequency counter .
• USE AS SQUARE WAVE OSCILLATOR.
The A0-3001C features excellent rising and falling characteristics.
It has no coupling capacitors in the output stage, so the SAG(deflectior. of top section) is as
low as 5% at 50Hz. By applying such a good squarewave to an amplifier input, various
characteristics of amplifier can be observed on an oscilloscope.
CAUTION
(1) CONNECTING LEADS SHOULD BE AS SHORT AS POSSIBLE.
Use of a long shield cable will affect high frequency amplitude characteristics because of
its own line capacitance.
(2) OUTPUT WAVEFORM AFTER SWITCHING ON.
Because of the use of direct coupled circuits throughout the entire stage, DC voltage will
appear about 20 to 30 seconds later when normal output waveform is obtained.
