From B&K Precision
If the amplitude and period of some reference signal are known, an unknown signal may be measured for amplitude and period without the variable input attenuator and variable time base controls set to the calibrated position. The measurement is made in units relative to the reference signal. 1. Apply the reference signal to the input jack and adjust the oscilloscope for a normal waveform display. Adjust the Volts/Div and variable input attenuator controls so that the amplitude of the reference signal occupies a fixed number of divisions. After adjusting, be sure not to disturb the variable input attenuator control setting. Products & Services
Signal generators and waveform generators are used to test and align all types of transmitters and receivers, to measure frequency and to generate a signal, waveform or noise source. Signal generators can use AC energy, audio frequency (AF) and radio frequency (RF) to function.
Computer-based instruments are part of a computer (a board, for example), or need to be connected to a computer in order to measure and display data.
Optical choppers are mechanical or electronic devices that pass and then interrupt a beam of light for a known brief interval. Optical shutters are used to control the amount of time that a light sensitive material is exposed to radiation.
Environmental controllers control environmental factors such as temperature, humidity, and air pressure. The environment to control can be an office or workspace, or inside a chamber for testing or process purposes.
Pulse generators are electrical test equipment used to generate pulses that are injected into devices under test in order to study the behavior of these devices.
