Quick Start: Pulse-Train Example
1.
Basic operation of the P400 may be demonstrated using its default
configuration. To invoke this mode, turn the unit off, and then turn it back
on while holding the numeric "0" key down.
2.
When the trigger screen appears and "LOADING DEFAULT CONFIG" is
displayed, release "0.” Press the START button to begin pulsing.
The default setup enables internal triggering at 1.00 KHz. Channels A, B,
C, and D produce sequential 100 microsecond positive pulses, with
baselines of 0 volts and pulse 4 volts into a high-impedance load.
3.
Connect an oscilloscope to the P400, with the T0 pulse applied to scope
Channel 1, and trigger on the rising edge of this signal.
4.
Connect available additional scope channels to P400 outputs A, B, C, and
D. Set the scope to 100
µ
sec/cm horizontal, 5v/cm vertical.
The scope display should look similar to that shown in Figure 3. The
traces are, from top to bottom, signals T0, A, B, C, and D. (Voltages are
not shown to scale in this figure.)
