5-36 Delta, Pulse Delta, and Differential Conductance
Fixed output
Figure 5-10
6221 outputs a low pulse, a high pulse, and then another low pulse during every
Pulse Delta cycle. The pulse width is adjustable and is the same for all high and
low pulses. The cycle interval is also adjustable and is based on the set number of
power line cycles. The Pulse Delta interval shown in
(power line cycles), which is the default setting. After the set interval expires, the
next Pulse Delta cycle starts (if pulse count is >1).
Pulses are synchronized to the frequency of the power line voltage. When Pulse
Delta is started, the three pulses (low, high, and low) are generated on the posi-
tive-going edges of the first three power line cycles. For the remaining power line
cycles in the interval, the output remains at the I-Low level.
