Astronics Test Systems Inc. Trig-Tek™ 45EMD Portable Calibrator The Trig-Tek™ 45EMD Portable Calibrator is designed to provide precision signals for field calibration of measurement instrumentation. Key Features • Laboratory accuracy • 10 to 9999 Hz (XTAL) • Set mV or pC level from 0.1 to 999.9 with a 0.1 resolution or from 1 to 9999 with 1 resolution • Differential pC output • Square wave output • Adjustable DC offset Product Information The Trig-Tek™ 45EMD Portable Calibrator is a convenient signal generator and is especially useful for field testing of monitoring systems. It has the required outputs to simulate a variety of pickups, temperature pressure, vibration (acceleration, velocity or displacement), or it can be used in a laboratory as a precision signal source. The 45EMD hand-held unit generates the required outputs to simulate a variety of transducers, including temperature, pressure, and vibration with laboratory accuracy. It is powered by a rechargeable NICAD battery and will operate for up to eight continuous hours on a single charge. The 45EMD’s output frequency is crystal controlled and accurate to 0.05%. Frequency is selectable from 10 to 999.9 Hz with 0.1 Hz resolution or 100 to 9999 Hz with 1.0 Hz resolution. A four-digit thumb switch and a “X1-X10” switch allow “pC” or “mV” level to be set from 0.1 to 999.9 with a 0.1 resolution or from 1 to 9999 with 1 resolution. 949.859.8999; 800.722.2528; [email protected]; www.astronicstestsystems.com Copyright © 2014 Astronics Test Systems Inc. Selectable output units include “DC,” “Pk,” “Pk-Pk,” or “RMS.” The “mV” output signal is on a BNC; the “pC” output is on a Microdot connector; and the differential (DIFF) pC output is on a three-pin connector. A DC offset voltage with selectable polarity can be superimposed on the AC outputs. Additionally, a constant 1 V synchronous Square wave output is provided. A DC offset voltage can also be superimposed on the AC output signals. This is accomplished by an “X1-OFF-X10” switch to allow settings from 0 to 1.2 and 0 to 12 V with a single turn control. The polarity of the “Offset” can be selected by the “+” or “–” switch. A battery charger is included, and a carrying case is optional. Trig-Tek™ 45EMD Astronics Test Systems Inc. Specifications Note: The Astronics Test Systems policy is one of continuous development and improvement. Consequently, the equipment may vary in detail from the description and specifications in this publication. Amplitude Interface The mV output is converted to pC at the pC output; the frequency is the same; the pC level is the same as the mV ±0.3%.
