The information describes these items: H Proper operating environment H Checking power cord and line voltage configurations H Checking the fuse H Power-on and power-off cycles Supplying Power Before installing the AWG2021, note these precautions: WARNING.
Preparation for Use Power Cord Information The AWG2021 ships with the required power cord as ordered by the customer. Table 2–1 gives the color-coding of the conductors in the power cord.

Preparation for Use Operating Environment To ensure proper AWG2021 operation and long life, note the following environmental requirements. Operating Temperature The AWG2021 operates in an environment with an ambient air temperature between +10_ C and +40_ C. The AWG2021 storage temperature ranges from –20_ C to +60_ C.
Preparation for Use Power Connector WARNING ATTENTION Fuse Principal Power Switch Figure 2-1: Rear Panel Controls Fuse Type and Rating The AWG2021 uses the same fuse for all operating line voltage ranges. One of two fuse types is installed in the instrument, depending upon the power cord option.
Preparation for Use Applying and Interrupting Power Consider the following information when you power on or power off the AWG2021, or when external power loss occurs. Power on Cycle At power-on, the start-up diagnostics check the AWG2021 operation. The start-up diagnostics take about 30 seconds. If all diagnostic items complete without error, the AWG2021 displays PASS on the screen and then changes to the SETUP menu.
Preparation for Use Memory Backup Power A lithium battery maintains internal nonvolatile memory, allowing the AWG2021 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 power-on may indicate that the battery needs to be replaced.
Preparation for Use Installed Options Your AWG2021 may include one or more options. To determine which options are installed, power on the AWG2021 and look at the display during the power-on sequence. The AWG2021 lists the installed options after Options, near the top of the display.
Operating Instructions Before servicing the AWG2021, read the following operating instructions. These instructions are at the level appropriate for servicing the AWG2021. The user manual contains complete operator instructions. In addition, section 4, Performance Verification, includes instructions for making the front-panel settings required to check AWG2021 characteristics. How to Power On To power-on the AWG2021, follow these steps: 1.
Operating Instructions The AWG2021 performs internal calibration routines using the Diag/Cal item in the UTILITY menu, which check internal circuit function and adjust calibration constants. Run these calibration routines whenever the AWG2021 undergoes a temperature change. For instance, run the calibration routines after the AWG2021 warms up at power-on.

Operating Instructions Side Menu When you select an item from the bottom menu, the corresponding side menu appears on the right side of the screen. To select an item, input numerals, or execute functions, push the soft button corresponding to the side menu item. Button Operation This area includes an explanation of front panel operation.
Operating Instructions H LOAD/SAVE Menu. Here are the functions for this menu: H The LOAD menu loads files from the AWG2021 floppy disk drive or nonvolatile internal memory into internal memory. H The SAVE menu saves files from the AWG2021 internal memory onto a floppy disk or into nonvolatile internal memory.
Operating Instructions Waveform Storage and I/O The AWG2021 has both internal memory and internal nonvolatile memory (NVRAM) for waveform file storage. The AWG2021 generates waveforms from files residing in internal memory. To save a file that is in internal memory, copy it to nonvolatile memory or floppy disk.
Operating Instructions Destination Source Figure 2-3: LOAD Menu Setting Output Parameters The SETUP menu allows you to set various output parameters for outputting a waveform or sequence waveform. To set the output parameters, select a waveform or sequence file (that is already loaded into memory) as the active file. When you select a file, the AWG2021 changes to the output parameters associated with the file and displays these parameters on the SETUP menu.
Operating Instructions Figure 2-4: SETUP Menu 2. Select Waveform Sequence from the bottom menu. 3. Turn the general purpose knob to highlight a file in the displayed list of files; these are the files currently in internal memory. Then push ENTER to select the file;...
Operating Instructions The clock period is the time between the data points for the waveform created. Therefore, the product of the clock period and the number of waveform points is the waveform or sequence period. For example, if the clock frequency is 1 MHz (period of 1 ms) and there are 100 waveform points, the waveform period is displayed as 100 ms.
Operating Instructions Figure 2-5: MODE Menu H Gated Mode. In gated mode, the gate signal controls the waveform or sequence output. As long as the front panel MANUAL button is pushed (or the gating signal is high), the AWG2021 outputs the specified waveform or sequence.
Page 59
Operating Instructions H Autostep Mode. Autostep mode uses the waveform file list and output parameter information in an autostep file. In this mode, the AWG2021 outputs one waveform when a trigger occurs, just as in Waveform Advance mode. The difference is that in this mode, the SETUP output parameters change with the waveform data.
