Channels toolbar

The Channels toolbar controls the settings for each vertical input channel. The

screen shot below shows the toolbar for a two-channel scope device, but different

scope devices may have different numbers of channels. (See also PicoLog 1216

toolbar that is used for the PicoLog 1000 Series.)

Each channel has its own set of buttons:

Channel Options button. Opens the Channel Options menu with

options for probes, resolution enhancement, scaling and filtering.

Range control. Sets up the scope device to capture signals over

the specified range of values. The list of options depends on the

selected scope device and probe. A red warning symbol - -

appears if the input signal exceeds the selected range. If you

select Auto, PicoScope will continually adjust the vertical scale so

that the height of the waveform fills as much of the view as

possible.

Coupling Control. Sets up the input circuitry.

AC coupling: rejects frequencies below about 1 Hz.

DC coupling: accepts all frequencies from DC to the scope's

maximum bandwidth.

50 DC: low-impedance option (see Device feature table).

Accelerometer: switches on the current source output for IEPE-

enabled scopes such as the PicoScope 4224 IEPE. The User's Guide

for the oscilloscope has details of the IEPE channel specifications.

Frequency: enable the built-in frequency counter if available.

Only one channel at a time can be operated in this mode. For

availability, see Device feature table.

Digital Inputs button (MSOs only).
