Use of STABILITY Control
1, Start with the STABILITY control turned
desired triggering mode.
2. Turn the STABILITY control left until
3. Turn the TRIGGERING LEVEL control
Adjustment of PRESET
See Calibration procedure for adjustment of
this control,
When you use the HF SYNC mode, you get
a recurrent horizontal sweep which can be
synchronized, by means of the STABILITY
control, with external waveforms in the range
from 5 megacycles to 15 megacycles.
1. Connect the source of the desired
synchronizing waveform tothe TRIGGER
INPUT connector.
2. Set controls as follows:
5X MAGNIFIER OFF
TRIGGER SLOPE +EXT. or
TRIGGERING HF SYNC
TRIGGERING not used in
STABILITY full right
3. Set the TIME/DIV. switch for a sweep
rate suited to the waveform being
4. Turn the STABILITY control slowly to the
left until you get a stable display of the
waveform being observed.
You can use the Type T to generate a
periodic sweep in a free-running manner,
independently of any external triggering or
synchronizing signal, This operation is useful
where the waveform being observed is initiated
by the output from either the + GATE OUT or
the SAWTOOTH OUT connector.
As an application of free-running operation,
you can actuate the system under investigation
by means of a signal from either the + GATE
OUT or the SAWTOOTH OUT connector. The
signals from these connectors have a starting
time and a duration corresponding to the starting
time and duration of the horizontal sweep.
Note that this reverses the usual situation
