4.6.2 Waveform Acquisition
The waveform acquisition mode allows voltage and/or current data waveforms
to be captured and displayed. This mode is selected by choosing the VIEW
=TRACE mode in the HARMONICS/TRACE ANALYSIS screen. Voltage and current
may be viewed separately or combined into a single display using the
FUNCTION field.
4.6.2.1 Acquiring waveform data
To perform a waveform acquisition on the output of the AC source, proceed as
follows:
1) Press the MEAS button four times or until the
HARMONICS/TRACE ANALYSIS screen appears.
2) Move the cursor to the FUNCTION field and select VOLT, CURR
or BOTH.
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.
