Set a Reference

The Ref button is on lower left of the ACV screen, opens a slide-out menu where you can set a new

Enter a Duty Cycle

Duty cycle adjustment is available for ACV when you select a square wave. After you select a square
wave with the Waveform Selection procedure outlined in
This toggles between OFFSET mode and DUTY CYCLE mode. The duty cycle value is adjusted in the
same manner as offset. If the mode is changed from offset to duty cycle, the offset is automatically set
to zero. If the mode is changed from duty cycle to offset, the duty cycle is set to 50 %.
To change the duty cycle of a square wave output:
1. Set the Product to output a 2 V p-p square wave at 1 kHz.
2. Tap the Mode softkey to show DUTY CYCLE.
3. Tap the duty cycle value.
4. Enter a new duty cycle between 1 and 99, or rotate the knob to slew to the desired duty cycle.
5. Push the E.

Set DC Current Output

To set the dc current output (Function > Single Output > DCI), refer to
example shown in Table
between VI AUX and OUTPUT LO or 30A and OUTPUT LO, depending on the current level selected.
Current >3.1 A is sourced between the 30A and OUTPUT LO terminals.
