3.14.6 Loading a Waveform into Execution Memory
To load a waveform into execution memory, specify its starting address and length in the ARB menu.
1. Select the channel to ON.
2. Press WAVEFORM and select the F5:ARB function.
3. Press F1:START to set the address. Valid entries range from 1 to 3,999,999.
4. Press F2:LENGTH to display the length of the waveform. Valid entries range from 2 to 4,000,000.
6. Use the rotary input knob or the numerical keys to enter the length of the waveform.
Note: The starting address always has to be an odd number. If an even number is entered, it will automatically
decrement one value to an odd number. For example, if you set start address to 2000 and press ENTER, it will
display 1999.
Note: The length value must always be an even number. If you input an odd number length, a message will pop up
and say “Even wave length” and then decrement one value to an even number. For example, if you entered 1001 as
the length, the message will pop up for one second and change the value automatically to 1000.
3.14.7 Generating a Waveform Output
Once you load a waveform into execution memory, you can output the waveform by setting the mode and output
parameters (frequency, amplitude, offset).
Setting the Mode
To set the mode:
1. Press MODE to display the Mode menu.
2. Press F1:CONT to select continuous mode, F2:TRIG to select triggered mode, F3:GATE to select gated mode,
or F4:BRST to select burst mode.
Setting the Output
To turn on the main output, press Output ON.
Modifying Waveform Output
You can modify the output of a waveform by:
* Using the offset
* Using modulation
3.14.8 Using Voltage Offset
Through the offset parameter you can add a positive or negative DC level to the output waveform.
To set voltage offset:
1. Press PARAMETERS to display the menu.
2. Press F3 :OFST to display the offset setting.
3. Use the rotary input knob or the numerical keys to set the voltage offset.
To turn the voltage offset OFF, repeat the steps above, but set the offset voltage level to 0.
