The output load can affect signal quality for pulse or other functions with high-speed transitions. High load res-
istance can produce reflections.
– Units are converted to Vpp if output termination is high impedance.
– You cannot change output termination with voltage limits enabled, because instrument cannot know which
termination setting the limits apply to. Instead, disable voltage limits, set the new termination value, adjust voltage
limits, and re-enable voltage limits.

Duty Cycle (Square Waves)
A square wave's duty cycle is the fraction of time per cycle that the waveform is at a high level (assuming the
waveform is not inverted). (See
– Duty Cycle: 0.01% to 99.99% at low frequencies; range reduced at higher frequency. Stored in volatile memory;
default 50%.
– This setting is remembered when you change to another function. A 50% duty cycle is always used for a
modulating square waveform; the duty cycle setting applies only to a square wave carrier.
