Increased Detector Sensitivity with TUNE Circuit

3 Increased Detector Sensitivity with TUNE and AMP. Circuits, [Pg.8]

When the power level is not high, it may be desirable to Increase the sensitivity of the indicating meter in order to obtain a more accurate null. This can be done with the TUNE circuit, as follows The meter switch now is set to TUNE. [Pg.8]

The TUNE knob is rotated for a maximum meter deflection. Measiirements are then made as before with increased meter sensitivity. [Pg.8]

Additional sensitivity can be obtained by switching the AMP. IN/OUT switch to the AMP. IN position. [Pg.8]
