With advanced DSP technology using Discrete Fourier Transform algorithms, the GP102A-PAV provides capability, performance and versatility not available with traditional PAVs. Targeted at the Synchro/Resolver and LVDT/RVDT marketplace, this instrument makes measurements of Phase Angle, In-Phase, Quadrature (90° component), Fundamental and Total Vrms very straightforward. All these measurements are displayed simultaneously on a bright multifunction display. The readout can even be zoomed to enlarge any selected measurement. Isolated inputs allow null, ratio (in-phase, quad, fund, total rms, sum+difference) and gain measurements of key parameters. A reference offset facilitates bridging measurements along with a sensitive null meter for precise nulling. An on-board reference generator (with optional amplifier) eliminates the need for an external reference; although the unit can be used with an external generator. Using an optional switching matrix (TAF01-U), LVDT, RVDT and resolver measurements can be automated. |
Onboard generator 500Vpk, DC - 2MHz PAV measurements Total vrms, in-phase, quadrature, phase angle, fundamental, frequency, all ratios, diff/sum ratio and analog style null meter High speed data output PAV parameters & watts at 1000 rdgs/sec for dynamic testing of motors, gyros and resolvers PC Software PAV measurement acquisition & display software and RS232 included, IEEE-488 optional |

Applications |
Typical applications for a phase angle voltmeters (PAVs) are found in the area of position sensing, motion and control. Devices like Resolvers, LVDT (Linear Variable Differential Transformers) and RVDT (Rotary Variable Differential Transformers), convert mechanical movement and position to electrical signals, feeding a control system. Position sensors are used in a variety of applications like aircraft instruments, aircraft control surfaces, inertial navigation, gyros, autopilot and weapon aiming systems. |
