Test and Measurement Tips
Basics of digital oscilloscope architecture
A digital storage oscilloscope (DSO) is characterized by the presence of a microprocessor, which is physically and functionally at the heart of the processing section. Other stages in the processor are the acquisition memory, at its input and the display memory at its output. The DSO’s signal paths (one for each channel) begin at the […]
Source measure units excel at high-accuracy, high-resolution testing
Three new Source Measure Units (SMUs) are designed for test applications that require high accuracy, high resolution and measurement flexibility, including current-voltage (I-V) characterizing and testing semiconductors, as well as other non-linear devices and materials. SMUs are electronic instruments capable of sourcing and measuring at the same time. They can precisely force voltage or current […]

These portable scopes have a compact footprint with BNC connectors that accept all common probes and accessories. With a high vertical resolution of 12 bits, 20-MHz bandwidth, 256-MSa buffer memory, and a fast sampling rate of 80 […]
Measuring the behavior of electronic filters
Passive electronic filters are composed of one or more passive components including resistors, inductors and capacitors. In contrast, active electronic filters also contain an amplifier composed of transistors or op-amps. The point of electronic filters is to pass some frequencies while blocking others. Depending upon the configuration, they selectively attenuate high frequencies (low pass), low […]
Monochromater boasts better wavelength accuracy and overall precision
The Oriel CS260B is a high-performance 1/4m configured monochromator that is a candidate for research applications and production environments. Each CS260B monochromator is a fully assembled, turn-key instrument and ready for immediate use. It leaves the factory pre-aligned and calibrated. Available options include different wavelength ranges, grating configurations and single or dual output ports. The […]
