Setting up Automatically: Autoset and Reset
The TDS Oscilloscope can automatically obtain and display a stable waveform
of usable size. It can also be reset to its factory default settings. This subsection
describes how to execute Autoset and reset, and lists the default settings in effect
after an Autoset.
Autoset automatically sets up the front panel controls based on the characteristics
of the input signal. It is much faster and easier than a manual control-by-control
setup. Autoset adjusts controls in these categories: Acquisition, Display,
Horizontal, Trigger, and Vertical.
Do the following steps to automatically set up the oscilloscope:
1. Press the channel selection button (such as CH 1) corresponding to your
input channel to make it active.
2. Press AUTOSET.
If you use Autoset when one or more channels are displayed, the oscilloscope
selects the lowest numbered channel for horizontal scaling and triggering.
Vertically, all channels in use are individually scaled. If you use Autoset when no
channels are displayed, the oscilloscope will turn on channel one (CH 1) and
scale it.
NOTE. Autoset may change vertical position in order to position the waveform
appropriately. It always sets vertical offset to 0 V.
If a standard mask is active, Autoset adjusts the selected trace to match the
mask, if possible. Vertical scale and offset, horizontal scale, trigger position, full
bandwidth, average, and trigger parameters are set as required for the standard.
If a calibrated optical probe is attached to Ch1 and an OC or FC standard is
selected, Ch 1 is selected and other channels are turned off.
