A lithium battery maintains internal nonvolatile memory, allowing the AWG2005 to retain waveform and sequence files if AC power is lost. This battery has a shelf life of about three years. Partial or total loss of stored information at powerĆon may indicate that the battery needs to be replaced. WARNING To avoid risk of fire or explosion, replace the AWG2005 battery with a lithium battery having the part number listed in section 10, MeĆ chanical Parts List.
Before servicing the AWG2005, read the following operating instructions. These instructions are at the level appropriate for servicing the AWG2005. The user manual contains complete operator instructions. In addition, section 4, Performance Verification, includes instructions for making the frontĆpanel settings required to check AWG2005 characteristics. To powerĆon the AWG2005, follow these steps: 1.
Instructions for Operation instance, run the calibration routines after the AWG2005 warms up at powerĆ on. This warmup period and subsequent calibration assures AWG2005 operation at optimum performance levels. User Interface The AWG2005 uses a combination of frontĆpanel buttons, keys, a knob, and onĆscreen menus to control generator functions. Some frontĆpanel controls select menus and manipulate menu items. Others enter values and units, allow manual triggering, and turn on/off AWG2005 output.

Instructions for Operation Menus The AWG2005 operation is primarily controlled by means of menus that correspond to the SETUP, MODE, EDIT, LOAD/SAVE and UTILITY buttons in the MENU column. To display one of these main menus on the screen, push the corresponding button. The button LED indicates which menu is currently selected. Refer to the User Manual for more details concerning these meĆ nus. The F.G button under the MENU column selects function generator operation.
Instructions for Operation Waveform Storage and I/O . This is the basic waveform data file. It contains the waveform data that the AWG2005 loads into memory and reads when generating waveform output. The data in this kind of file can be created using the waveform editor, generated from equations made using the equation editor, transferred in over an interface, or directly transferred in from certain Tektronix instruments.
Instructions for Operation Destination Source Figure 2Ć4:ăLOAD Menu 3. Push the Device button along the bottom menu to select Disk. The menu in Figure 2Ć4 appears. 4. Select the Load All button along the side menu to load all files in the root directory on the disk into the AWG2005 internal (volatile) memory. Or, turn the generalĆpurpose knob to highlight the file you want to load and select Load. The display indicates which file it is loading. When loading is complete, the clock disappears. 5.
! " ! ! The following steps go through the process of selecting a file and modifying individual output parameters. 1. Push the button in the MENU column. The SETUP menu in Figure 2Ć5 appears. " % $ " 2. Select # " from the bottom menu. Waveform SeĆ quence toggles between the CH1 files (upper list) and the CH2 files (lower list). 3.
The following explains each item in the bottom menu. Ċ This item sets the clock source and clock frequency. The clock source can be set to either internal or external. The clock period is the time between the data points for the waveĆ form created. Therefore, the product of the clock period and the number of waveform points is the waveform or sequence period.
# " Ċ In triggered mode, the AWG2005 outputs the specified waveform or sequence waveform once, when a trigger occurs. Ċ In gated mode, the gate signal controls the waveĆ form or sequence output. As long as the front panel MANUAL button is pushed, (or the gating signal is high) the AWG2005 outputs the specified waveform or sequence. When the MANUAL button is released (or the gating signal goes low), the waveform output stops.
Instructions for Operation Continuous Ċ In this mode, the first waveform is output over and over again for each channel when a trigger signal is received. When the next trigger signal is received, output of the first waveform stops after the end point of that waveform and then the second waveform is output in the same manner. The next waveform is not started at the moment a trigger is received, but rather at the completion of the previous waveform.
Instructions for Operation Step Ċ When a trigger signal is received, the Step:1 waveform for each channel is output once. When the next trigger signal is reĆ ceived, the Step:2 waveform is output (once). When the next trigger signal is received while waveform output is in progress, output stops after the end point of that waveform and then the waveform for the next step is output. 3. Set the trigger (gate) conditions for the external trigger (gate) source.
Theory of Operation This section describes the basic operation of the major circuit blocks or modules in the AWG2005. Section 9, , includes two block diaĆ grams and an interconnect diagram. Figure 9Ć1 shows the modules and functional blocks of the AWG2005 with Option 02, 04, 05 and 09 installed. Figure 9Ć2 shows how the modules interconnect. Module Overview The module overview describes the basic operation of each functional circuit block.
Theory of Operation DigitalĆtoĆAnalog Converter (DAC) (A11 D/A Board) This functional block is a 12Ćbit highĆspeed digitalĆtoĆanalog converter. It converts the digital data from the waveform memory into analog signals. Analog Processing (A3/A23 Analog Board) This analog processing block amplifies the analog signals from the DAC to the necessary amplitude. If an offset is specified, this circuit adds that offset and outputs the result at the output connector for that channel.
Theory of Operation Display Monitor The display monitor takes in the video signals and displays them on a 17.8Ăcm (7 in.) CRT screen. The display resolution is 480 640 pixels. Front Panel (A12 Key Board) The front panel block includes the buttons, keys, knobs, and so on, for entering selections. User selections from the front panel are sent to the processor. The buttons at the bottom and side of the display are also inĆ cluded in this block. Commands from the processor control the LED in the buttons.
Theory of Operation Options The following four options which modify AWG2005 operation are available. Option 02: CH3 and CH4 Output Channels Option 04: Digital Data Out Option 05: Clock Sweep This option provides an additional function: the clock sweep editor. In addition to performing linear sweep and log sweep for the clock freĆ quency, the clock sweep editor enables you to easily create arbitrary sweep. The Clock board for the AWG2005 standard type is replaced by the Clock Sweep board.
