Programmable Audio Generator

ANL-926
Programmable Audio Generator

This programmable audio generator is a single width module that contains a pure tone, white noise, and click generator under a single microprocessor controller and audio amplifier rated at 675 mW max into 8 ohms. Install into the interface cabinet for each test chamber in the system. The frequency and amplitude specifications may be limited by the cage speaker.

Dimensions:
0.875" W x 5.25" H x 7.25" D
(2.2 cm x 13.3 cm x 18.4 cm)

Pure Tone:
Frequency: 10 to 35,000 Hz in 1 Hz increments. 
Amplitude: 20 to 100 dB in 0.5 dB increments 
± 1 bit (0.125 dB). 
Rise/Fall time: 1 milliseconds to 1 second in 0.1 ms increments. 
Duration: 1 millisecond to over 1 minute (65,535 ms) plus 
continuous (timed by MedState NotationT). 

White Noise: 
Frequency: Broad band white noise selected by freq = 0. 
All Others: Same as pure tone. 

Clicker: 
Frequency: 1 to 10 Hz
Rise/Fall: Disabled.
Amplitude: Fixed.
Duration: Same as pure tone.

ENV-230
Multipurpose Sound Generator

This convenient multipurpose sound generator that is able to produce three different types of sound; white noise, clicks and pure tones. Sound type is selected by manually moving switches up or down. Both the volume and duration of each sound are adjustable.

Dimensions:
3.1" W x 2.7" L x 1" H
(7.9 cm x 6.9 cm x 2.5 cm)

ENV-223
Multiple Tone Generator

This multiple tone generator uses four 28 V DC outputs to select between 15 different frequencies ranging from 1 KHz to 20 KHz. It employs a fixed rise/fall so there is no speaker click or pop when turning on the tones. The volume of the tones may be adjusted using a screwdriver. This may be used with speakers (ENV-224AM, ENV-224BM, ENV-224CM, ENV-224DM, or ENV-324W) depending on the application and frequencies desired. If greater control over the frequencies, rise/fall time, and volume is desired, refer to the programmable audio generator (ANL-926).

Dimensions:
2.4" W x 2.27" L x 1.0" H
(6.1 cm x 5.8 cm x 2.5 cm)
