A-003-03-04:
A dip meter supplies the radio frequency energy which enables you to check:
the resonant frequency of a circuit
the calibration of an absorption-type wavemeter
the impedance mismatch in a circuit
the adjustment of an inductor
A-003-03-05:
A dip meter may not be used to:
measure the value of capacitance or inductance
align transmitter-tuned circuits
determine the frequency of oscillations
align receiver-tuned circuits
A-003-03-06:
The dial calibration on the output attenuator of a signal generator:
reads accurately only when the attenuator is properly terminated
always reads the true output of the signal generator
reads twice the true output when the attenuator is properly terminated
reads half the true output when the attenuator is properly terminated
A-003-03-07:
What is a signal generator?
A high-stability oscillator which can produce a wide range of frequencies and amplitudes
A low-stability oscillator which sweeps through a range of frequencies
A low-stabilty oscillator used to inject a signal into a circuit under test
A high-stability oscillator which generates reference signals at exact frequency intervals
A-003-03-08:
A dip meter:
should be loosely coupled to the circuit under test
should be tightly coupled to the circuit under test
may be used only with series tuned circuits
accurately measures frequencies
