Application of Free-Running Operation
Sometimes it is desired to display the output of a device
which requires a triggering signal for each cycle of output,
such as a monostable or bistable multivibrator. In this case,
the Type 516 Oscilloscope can be used for triggering the
device as well as displaying its output waveform. To set the
oscilloscope up for this type of operation, proceed as
follows:
1. Set the STABILITY control fully clockwise.
2. Connect a lead between either the + GATE OUT con­
nector or the SAWTOOTH OUT connector and the input to
the device under observation. (The signal at the +GATE
OUT connector has an amplitude of about 25 volts and the
signal at the SAWTOOTH OUT connector has an amplitude
of about 150 volts,- therefore, it may be necessary to scale

these down by means of a voltage divider, depending upon
the equipment with which they are to be used.)
CAUTION
To avoid shorting out the + g a te or sawtooth
voltage from the oscilloscope, make the connection
to the device under observation before connecting
the lead to the oscilloscope connector. Do not con­
nect a resistance o f less than about 2k between the
+ GATE OUT connector and ground, or less than
about 10k between the SAWTOOTH OUT connec­
tor and ground; to do so might damage compo­
nents in the oscilloscope.
3. Connect the output of device under observation to the
vertical input connector of the Type 516.
The output of the device will now be synchronized to the
free-running sweep of the oscilloscope and will appear as a
stable display on the screen.
