Getting Started with the TDS1000B and TDS2000B Series Oscilloscopes
FORCE TRIG button
You use this button to force a signal acquisition to occur in
the absence of a trigger signal. This manual trigger
function can become necessary when you set the
triggering mode to Normal, or you select SINGLE SEQ
with the front panel button for this mode.
TRIG VIEW button
You use this button to display the trigger waveform
instead of the channel waveform. You can use this button
to check how trigger settings, such as trigger coupling,
affect the trigger signal. You need to keep this button
pressed to view the trigger waveform.
Warning: If the oscilloscope is incorrectly triggered, the
display may not represent the signal connected to the
probe. Instead, the display may show a previous safe
reading when a dangerous voltage is actually connected to
the input.
