General; Externat Input Characteristics - HP 8082A Operating And Service Manual

GENERAL

3 - 2 This section is divided into two parts. The
first part gives scrme general notes on the operation of
the SO82A together with operating instructions for each
of the four operating modes:
NORM operating mode
EXT WfDTH operating mode
GATE operating mode
EXT TRiG operating mode
Full setting-up instructions are given for Normal mode
followed by any changes in control settings required for
the other three modes. Stylized waveforms are given for
each mode to show the resultant pulse shapes. For ease
of operation the instructions will refer to Figure
which shows the controls identified by a reference num-
ber in a circle. The same reference numbers are used in
the text when each control is mentioned.
3 - 3 The second part of this section gives appli-
cations information.
3 - 4 EXTERNAL lNPUT
CHARACTERISTICS
3 - 5 The SLOPE/POLARITY switch determines
whether a rising (POS) or falling (MEG) signal will trigger
or gate the external input on. Figure 3-2 shows the effects
of these controls in the External Width mode.
