Recommended separation distances between portable and mobile RF communications equipment and the 1001 This Model 1001 is intended for use in the electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of the 1101 can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the 1001 as recommended below, according to the maximum output power of the communications.
Controls and Connectors Signals to be processed are connected to the Audio Monitor at these two BNC jacks (Ch. 1 and Ch. 2). INPUT: This toggle switch determines which of the two input signals will be processed. CHANNEL: This three position switch controls the level of signal gain. The switch allows the user to select from X1, X10, or X100 gain. GAIN: In the ON position, this filter will attenuate line noise (Either 50 or 60 Hz, depending on the country of use).
Operating Instructions Typical Set-Up Procedure Turn the VOLUME control to the off position prior to connecting an input signal to either of the two input channels in order to prevent damage to the internal speaker or any nearby eardrums. Using the Channel Switch, select the desired input signal channel to be amplified. Determine the gain setting. Start with the lowest GAIN setting possible, and slowly increase the VOLUME control until a desired audio level is obtained.
Theory of Operation One of two inputs may be selected using the CHANNEL switch. The selected input is then amplified according to the setting of the GAIN switch. After amplification, the signal can be filtered at the frequency of the power line by use of the NOTCH filter. Particular narrow ranges of frequencies of the processed signal can then be boosted or attenuated using the GRAPHIC EQUALIZER. Maximum boost or attenuation is +/12dB, centered on the frequency indicated under each slide knob.
