Uses for Electrical Meters Part 1
are here to help with a guide to different meters and their typical uses. This week we are going to focus on voltmeters, resistivity meters, and nanocoulomb meters. Be sure to check back next Monday for more!. Voltmeter: As the name suggests, these meters measure voltage. Voltage is the “power

Agilent: Spectrum Analysis Basics
This application note is intended to explain the fundamentals of swept-tuned, superheterodyne spectrum analyzers and discuss the latest advances in spectrum analyzer capabilities. At the most basic level, the spectrum analyzer can be described as a frequency-selective, peak-responding voltmeter

Software Implementation of Asynchronous Serial I/O
Voltmeter (DVM)/Analog Data Acquisition System has been implemented using a PIC16C71, in which, upon reception of a command from host (IBM PC-AT Ò ), an 8-bit value of the selected A/D channel is transmitted back to the host. Software Implementation of Asynchronous Serial I/O. M. AN555. Software

One scope, many faces
difficult. Traditionally, voltmeters, logic analyzers, and oscilloscopes were the staples of testing and troubleshooting. With mixed signal designs becoming more prevalent, the average engineer's bench is increasingly stacked with one or more of these instruments. However, a mixed-signal oscilloscope

Temperature sensors: Thermocouples
to a sensitive voltmeter forms a simple high-temperature thermometer called a pyrometer. The simplicity of a thermocouple is offset by two problems. First, the voltage output is not linear with temperature. In the simple pyrometer, the meter uses a nonlinear scale drawn to match the calibration curve
