The manual for the B&K Model 3001 Audio Generator covers setup and operation by detailing how to select frequency, waveform, and attenuation, as well as how to connect outputs to test points. It also provides troubleshooting tips, such as checking the battery indicator and ensuring proper connections, to maintain optimal performance.
Manual Overview
The B&K Model 3001 Audio Generator manual provides detailed guidance on troubleshooting, diagnostics, calibration, and board-level adjustments. For troubleshooting, the manual emphasizes the importance of ensuring proper connections and settings, such as verifying the frequency selection dial and FREQ. RANGE switch settings. Error diagnostics involve checking the LO BAT indicator, which signals when the battery needs replacement. Calibration is achieved by adjusting the frequency selection dial and amplitude control to ensure accurate output levels. The manual specifies that the output frequency is determined by multiplying the frequency dial setting by the FREQ. RANGE switch setting. For board-level guidance, the manual highlights the use of the SYNC jacks for constant-amplitude sine wave output, useful for triggering other instruments or monitoring with a frequency counter. The manual also advises on safety precautions, such as using insulated surfaces and being aware of high voltage areas, to prevent personal injury during operation.

Controls & Indicators
The front-panel controls and indicators for the Model 3001 Audio Generator include:
1. WAVEFORM Switch: Selects sine wave or square wave output at the OUT jacks.
2. Frequency Selection Dial: Determines output frequency and also turns the unit on/off. The setting is multiplied by the FREQ. RANGE switch.
3. FREQ. RANGE Switch: Multiplies the setting of the frequency selection dial by X1 or X100.
4. LO BAT (Low Battery) Indicator: Indicates when the battery should be replaced.
5. AMPLITUDE Control: Varies the amplitude of the waveform at the OUT jacks.
6. SYNC Jacks: Provide a sine wave of constant amplitude, same frequency as the signal at the OUT jacks.
7. OUT Jacks: Main output for sine wave or square wave, with variable amplitude and frequency.
8. ATTENuation Switch: Selects 0 dB or -20 dB attenuation, affecting the signal at the OUT jacks only.
Installation / Setup

Operation
To operate the Model 3001 Audio Generator, follow these steps:
1. Turn the unit on using the frequency selection dial, which also acts as the on/off control.
2. Select the desired frequency by adjusting the frequency selection dial and the FREQ. RANGE switch. The output frequency is determined by multiplying the frequency dial setting by the FREQ. RANGE setting.
3. Choose the desired waveform (sine or square wave) using the WAVEFORM switch. This affects the signal at the OUT jacks.
4. Set the desired attenuation using the ATTEN switch. 0 dB means no attenuation, while -20 dB applies an attenuation factor of 10 to the signal at the OUT jacks.
5. Adjust the output signal level using the AMPLITUDE control, which affects the signal at the OUT jacks.
6. Connect the generator outputs to the desired test points. The OUT jacks provide the main output, which is frequency- and amplitude-variable. The SYNC jacks provide a constant-amplitude sine wave with the same frequency as the waveform at the OUT jacks, useful for triggering other test instruments or for constant monitoring with a frequency counter. The common terminals of the SYNC and OUT jacks are internally connected.
Remember to turn the unit off between uses to conserve battery life.

Safety & Warnings
The manual contains the following safety warnings and precautions:
1. The Model 3001 itself produces no hazardous voltages, but it may be used in equipment where high voltage is present. Voltage as low as 35 V DC or AC RMS can be hazardous because it may produce a lethal current.
2. Familiarize yourself with the equipment being tested and the location of its high voltage points. High voltage may appear unexpectedly in defective equipment.
3. Use insulated floor material or an insulated floor mat, and place equipment on an insulated work surface. Ensure these surfaces are not damp or wet.
4. In AC powered equipment, line voltage may be present on power input circuits even if the equipment is turned off.
5. Some equipment with a two-wire AC power cord may be of the “hot chassis” type, posing a serious shock hazard if the chassis is touched. Use an isolation transformer for testing such equipment and treat all two-wire corded equipment as “hot chassis” unless certain of an isolated or grounded chassis.
6. Never work alone; someone should always be nearby to render aid. Training in CPR is recommended.
