When using a conventional oscilloscope probe, the display will be an envelope such as shown in Fig. 10. The relative gain or attenuation of all frequencies within the swept band is displayed. The display may be analyzed for acceptable or unacceptable frequency response characteristics. In wideband amplifiers, the objective is usually to maintain a flat frequency response over the widest possible bandwidth. Frequency response displays of filters and coupling networks show the cut-off frequency and the sharpness of the cutoff. The frequency response display is often the basis for alignment of RF circuits (Figs. 16 & 17). The display also may be analyzed to determine the center frequency of band pass, symmetry of band pass, bandwidth, gain or signal amplitude, Q, and rejection of adjacent frequencies. Products & Services
Frequency converters and translators scale and/or filter frequency inputs to produce outputs signals with frequencies that are a function of the inputs.
Active band pass filters are used to attenuate frequencies below and above a range of frequencies (i.e., the bandwidth or passband of the filter).
Bridge conditioners are instruments that provide excitation and support for strain gages, Wheatstone bridges, load cells, and sensors. They also include circuitry for signal conditioning, amplification, and processing.
Data acquisition input modules accept sensor and other signal output for data acquisition systems. They may include signal conditioning prior to the analog-to-digital conversion stage.
Charge converters and charge amplifiers convert the charge output from a piezoelectric, capacitive or other charge-producing sensor to a signal such as analog voltage or current.
