AN302: Considerations for Selecting a Power Amplifier
This Application Note is intended to help individuals who are not power amplifier experts to understand the basic parameters such as Gain, Bandwidth (BW), Slew Rate (SR), Total Harmonic Distortion (THD), Input Impedance and Current Limit necessary to properly select an amplifier for use in testing and experimentation.
AN400: The Advantages of Multiple Sync Outputs in AWG’s
The purpose of this application note is to provide a summary of the synchronizing outputs of TEGAM’s arbitrary waveform generators (AWGs), and to offer a quick-start guide for their operation and use.
AN401: True vs. DDS Arbitrary Waveform Generators
The purpose of this application note is to provide an understanding of the basic differences between True and DDS Arbitrary Waveform Generators. With AWGs, there are two fundamental design variations: DDS (Direct Digital Synthesis) and True (Traditional) Arbitrary Waveform Generators. Each design variation has its own unique advantages and disadvantages. Because the application determines instrument selection, an understanding of the basic differences between True and DDS AWGs is highly beneficial.

AN403: Using Arbitrary/Function Generators to Simulate Polyphase Power Line Waveforms
Polyphase signal generation is required for a broad range of test applications. For example, it is used in condition monitoring or fault detection systems. These tests require the simulation of three-phase sine waves with line frequencies, ranging from 50 – 800 Hz, where fault conditions or high frequency noise are introduced. Three-phase AC power supplies may be considered; however, they are restricted by bandwidth limitations, cost and the inability to recreate real-world waveforms. TEGAM’s 2700A series arbitrary/function generators address the synchronization, phase shift and resolution issues and are ideal for simulating pulse, noise, sensor stimuli, speed profiles or faults.

AN504: Increasing the differential voltage range of TEGAM 4040A
The TEGAM Model 4040A expands the measurement range of PXI digitizers and scopes from 2 mV to 100 V. Although this range appears fairly wide, there are some applications which require a wider range. The measurement range of a PXI system can be expanded up to 1200 Vpk by combining a TEGAM 4040A with x10 or x100 probes.
