Figure 2.3: Channels Conﬁguration, Square Interface

• The Square channel mode allows the creation of a square TTL pulse sequence. This includes all sequence

options as the CW mode, with the following additions.

i. The Frequency (Fig. 2.3) sets the frequency (in Hz), which is the number of pulses per second. The

frequency 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).

ii. The Time ON (Fig. 2.3) deﬁnes the length of a single pulse. This time can also be converted to a Duty

Cycle, which represents the % of the period the pulse duration corresponds to.

iii. The Pulse(s) per sequence (Fig. 2.3) set the number of pulses per sequence. If it is set to 0, the

number of pulses will be inﬁnite.

iv. The Number of sequence(s) (Fig. 2.3) sets the number of times that the sequence will be repeated.

v. The Delay between sequences (Fig. 2.3) sets the delay between each sequence.
