@ At Button
1/At
Function
Controls, Connectors, and Indicators
Activates the Delta Time measurement function and
cancels the
AV or 1/At measurement functions. When At
is selected with Inten or Alt horizontal display modes,
two delay times are defined. When At is selected with
either A-Sweep
or B-Sweep horizontal display, two
vertical cursors are established. One delay time or
cursor position is controlled by the A REF OR DL Y POS
control, and the other is controlled by the A control. The
CRT readout displays either the difference between the
two delay times or the equivalent time between the
vertical cursors.
If SEC/DIV VAR is not in the detent position, and either
the A-Sweep or the B-Sweep horizontal display mode
is
selected, the CRT readout displays delta-time as a ratio,
where five divisions correspond
to 1 00% ratio.
When
At is active, pressing the At button deactivates
the function.
Momentarily pressing the
At and AV buttons
together activates the 1/Delta-Time function and
cancels any other Delta measurement function. The
waveform display and the Delta controls operate the
same as for
At, but the readout shows the reciprocal
of the time in Hz (frequency).
If the SEC/DIV VAR control is not in the detent
position (full clockwise rotation), and the A-Sweep or
B-Sweep horizontal display mode is selected, the
readout displays the time between cursors as
degrees of phase, where five divisions are equal to
360 degrees.
When the 1/Delta Time function is active, pressing
the
At and AV buttons together deactivates the
function.
