If the standing wave ratio is greater than what, then the transmission line efficiency has decreased and troubleshooting is necessary?
1.5 to 1
What are used to test and align all types of transmitters and receivers?
Which devices are used in signal generators to regulate the voltage of the output signal?
What produce signals that include the audio range and extend into the rf range?
Video signal generators
In addition to the necessary power supply, a typical rf signal generator contains three other main sections: an oscillator circuit, modulator, and what else?
Output control circuit
HP 8640B signal generator covers the frequency range of 500 kilohertz to 512 megahertz, and can be extended to what by using adapters?
What are used to measure frequencies already in existence?
What is an integrated circuit-testing device?
Some logic probes have a feature that detects and displays high-speed transient pulses as small as how many nanoseconds wide?
How many impedance ranges can be selected on the Tracker 2000?
What produces a constant amplitude, low distortion sine wave test signal?
