Output level
Sets the low level of the output pulse. The high level is 0 V and cannot be changed.
Remote command:
PSRC:OUTPutlow on page
2464
Repetition rate
Sets the pulse frequency
, the repetition rate of the pulse. Available values depend on
the selected clock mode.
Remote command:
PSRC:REPRate on page 2465
Duty cycle
Sets the duty cycle of the pulse in %, which is the ratio of the positive pulse width to
the period of the signal.
For repetition rates > 5 MHz, the value is fixed at 50 %.
Remote command:
PSRC:DUTYcycle on page 2465
Clock mode
Sets the dependency of the pulse clock on the instrument's reference clock. The
appropriate clock mode depends on the measurement application.
"Free running"
The clock of the pulse source is independent. Deviations of the sys-
tem do not affect the pulse clock, and deterministic conditions are
avoided.
If the waveform aquisition is set to "A
verage", the "free running" clock
mode can improve the measurement result. Internal spurious signals
of the instrument are reduced by averaging, because they are not
coherent to the pulse source signal.
See also: "Arithmetic" on page 130.
"Locked"
The pulse source is locked to the reference clock of the instrument.

Preset
Resets the pulse source to the default state. Pulse source settings are not are not
af
fected by an instrument preset. They are also not stored in the user-defined preset.

16.2 TDR/TDT analysis (option R&S RTO6-K130)
The option R&S RTO6-K130 provides analysis of time domain reflectometry (TDR) and
time domain transmission (TDT) to verify high-speed digital designs. Using the results
of the TDR/TDT calibration, the instrument removes the effects of the cables (deem-
bedding), and measures the DUT.
