Chapter 1 Quick StartTo output a dc voltageTo output a dc voltageIn addition to generating waveforms, you can also output a dc voltage inthe range – 5 Vdc (into a 50W termination). The following steps showyou how to output +155 mVdc.1 Press the Offset key and hold it down for more than 2 seconds.To enter the dc voltage mode, press the Offset key or any key in thetop row of function keys and hold it down for more than 2 seconds.The displayed voltage is either the power-on value or the previousoffset voltage selected.DCV+0.000 VDCEnter Number1 5 52 Enter the magnitude of the desired voltage.Notice that the Num annunciator turns on and “ENTER NUM” flashes onthe display, indicating that the number mode is enabled.1155To cancel the number mode, press Shift Cancel .Shift¿kHzm Vrms3 Set the units to the desired value.At this point, the function generator outputs the displayed dc voltage.Notice that the Offset annunciator turns on (all other annunciatorsare off), indicating that a dc voltage is being output. The annunciatorwill turn on when the offset is any value other than 0 volts.+155.0 mVDC1 You can also use the knob and arrow keys to enter a number.See “Front-Panel Number Entry” on page 3 for more information.24
