4.6.2.1 Acquiring waveform data
allows voltage and/or current data waveforms to be captured
cted by choosing the VIEW =TRACE mode in the
S screen. Voltage and current may be viewed separately or
sing the FUNCTION field.
To perform a waveform acquisition on the output of the AC source, proceed as follows:
ss the MEAS button four times or until the HARMONICS/TRACE ANALYSIS screen
ears.
e the cursor to the FUNCTION field and select VOLT, CURR or BOTH.

2. Mov
3. Move the cursor to the VIEW field and select the TRACE display mode.
4. Skip the DATA MODE field as it only applies to the TABLE and BAR display modes.
5. Move the cursor to the SCALE field and select a horizontal time base value to allows you to
see at least one cycle of the output waveform. If the output is programmed at 50 Hz, a 20
ms scale would display exactly one signal period.
6. Move the cursor to the TRIG MODE and select SINGLE or CONT. The SINGLE mode will
acquire the data once and show the result. If you select CONT, the data will be updated
continuously.
7. Move the cursor to the TRIG SOURCE field and select IMM. We will cover additional trigger
modes later.
8. Move the cursor to the START field and press the ENTER key. The display that you
selected will be shown. If you are in CONT trigger mode, the data will be updated about
once per second.
You can return to the HARMONICS/TRACE ANALYSIS screen by pressing the ENTER key. To
display the data in a different format or to select voltage instead of current or current instead of
voltage, change to the selections you want and move the cursor to the VIEW field. Pressing the
ENTER key will re-display the data without triggering a new acquisition. (This is true even if you
were in CONT trigger mode.) To start a new acquisition, you must go through the START field
instead.
