4.3.3 Change Output Values with the Knob in SET Mode
The SET mode of operation is a mode in which changes to output parameters made with the
knob or the entry keypad do not affect the output until the ENTER key is pressed. The AC source
is put in this SET mode by pressing the SET key.
To change the output voltage:
Counter
Clock
wise
Clock
wise
INCR DECR
1. Press the SET key
2. Place the cursor on the VOLTAGE entry
3. Rotate the knob clockwise to increase the value, counterclockwise to decrease the value
4. The VOLTAGE field will be blinking to indicate a change in settings but the output remains
unchanged.
5. Place the cursor on the FREQ entry
6. Rotate the knob clockwise to increase the value, counterclockwise to decrease the value
7. The FREQ field will be blinking to indicate a change in settings but the output remains
unchanged.
8. Press the ENTER key.
Both new voltage and frequency output values are now present at the output. The unit has
returned to immediate mode of operation until the SET key is pressed again.
4.4 Waveform Management [iX Series only]
The iX Series employs independent arbitrary waveform generators for each phase. This allows
the user to create custom waveforms. In addition, the iX offers three standard waveforms that
are always available. This chapter covers issues that relate to defining, downloading and
managing custom waveforms.
4.4.1 Standard Waveforms
For many AC applications, a sinewave shape is used. The sinewave is one of the standard
waveforms provided on the iX Series. The standard sinewave is always available and is the
default waveform at power-on. In addition to the sinewave, two more standard waveforms are
available, square and clipped.
