Figure 3.11:
Channel(s) configuration window, Analog Output Square
• The
Square
channel mode (Fig.
) creates a sequence of pulses with the minimum of the pulses at
V-
and the
maximum of each pulse at
V+
. This includes all sequence options as the
CW
mode, with the following additions.
1. The
Frequency
(Fig.
) sets the frequency (in Hz), which is the number of pulses per second. The fre-
quency can also be changed to the
Period
. For example, a signal at 10 Hz (frequency) will output one pulse
every 100 ms (period), whereas a signal at 0.5 Hz (frequency) will output one pulse every 2 seconds (period).
2. The
Time ON
(Fig.
) defines the length of a single pulse. This time can also be converted to a
Duty Cycle
,
which indicates the % of the period the pulse duration corresponds to.
3. The
Maximum Voltage (V+)
(Fig.
) defines the maximum voltage of each pulse, in volts. The signal cannot
go 4.75 V.
4. The
Minimum Voltage (V-)
(Fig.
) defines the minimum voltage of each pulse, in volts. The signal cannot
go beyond -4.75 V.
5. The
Pulse(s) per sequence
(Fig.
) set the number of pulses per sequence. If it is set to 0, the number of
pulses will be infinite.
6. The
Number of sequence(s)
(Fig.
) sets the number of times that the sequence will be repeated.
7. The
Delay between sequences
(Fig.
) sets the delay between each sequence.
