Page 37 There are several options available for the AWG2005, including four channel output, clock sweep, digital data output, and FFT and convolution waveform editor. These options allow the AWG2005 to handle a wide range of applica tions. This instrument has four editors for making waveform files. Each editor is equipped with a variety of editing functions, as described below.
Page 38 The AWG2005 has a 3.5 inch floppy disk drive and non volatile memory for storing created waveform data and parameter settings. Each of these stor age devices can store the files created with the editors.
Page 39 Step 1: Check that the operating environment is correct. The AWG2005 operates correctly in ambient temperatures from +10°C to +40°C and relative humidity from 20% to 80%. If this instrument is stored at temperatures outside this usage temperature range, do not switch on the power until the chassis has come within the usage tem perature range.
Page 40 CAUTION Instruments are shipped with a power cord appropriate for use with normal 115 V power systems. If the AWG2005 is to be used with 230 V power, the power cord must be replaced with one appropri ate for the power source used. See Figure 1 2, "Optional Power Cords", for the available power cord types.

Page 142 Block Diagram Sequence The sequence memory has a capacity of 32 K words, with each word com posed of 16 bits. When a file has been selected with Waveform Sequence in the SETUP menu, data items such as the address of the waveform written to the waveform memory, the number of loops for the waveform or se quence, and the operation mode are written to the sequence memory.
Page 143 For example, when outputting triangular waveforms, about 8000 points are needed to minimize the jaggedness of the waveform. That is why the AWG2005 uses a DAC with a resolution of about 4000 (12 bits) for the vertical amplitude. Figure 3 7 shows the relationship between the triangular wave resolution and the number of data points.
Page 144 In order to eleiminate overshoot and ringing, the filters in the AWG2005 have Bessel characteristics with relatively gentle shoulder characteristics, That is why more points are required.
Page 145 These filters can be used to remove unnecessary frequency elements from the waveform itself or reduce the number of elements through reflection when the waveform is made up of a limited number of points. 3 13 AWG2005 User Manual www.valuetronics.com...

The AWG2005 can be used without terminating the receiving (user) side with a resistance of 50 W, but when waveform distortion is great the 50 W termination is required.

Page 546 Appendix D: Miscellaneous point, this is enough. Since the non DC components have energy dispersed on both the positive and negative sides, the DC component is 2x the other components. Since the DC component is scaled by 1/2 with the FFT editor, DC and the other components can be handled equally.
