Installation / Setup
The source does not provide specific information about installation or setup highlights, including wiring, clearances, calibration, or prerequisites.
Operation
The operating instructions for the B&K/Precision Model E-301B Sine/Square Wave Generator include the following basic usage steps:
1. Before connecting the generator to a circuit, determine the signal level normally present in the circuit to prevent damage from excessively high input signals.
2. Set the OUTPUT LEVEL control towards minimum and place some of the ATTENUATOR switches in the IN position as a precaution.
3. If the signal injection point has a d-c potential, use a capacitor in series with the generator output to avoid loading d-c circuits and protect the attenuator network. The capacitor value should be based on the input impedance of the circuit and the frequency range to be tested.
4. Use shielded cable to connect the generator output to the circuit under test, especially for distortion measurements and stage gain checks at low frequencies and output levels. Unshielded leads are suitable for non-critical applications.
5. A VTVM should be used to monitor the output level.
