Select offset and amplitude format for the pulse levels. Offset is
measured from 0V to the middle of the pulse amplitude. Pulse
amplitude is the difference between the high and low levels of the
pulse.

ECL
Select high and low level format and automatically set the levels to
the default ECL levels:
ECL-HI: 850 mV
ECL-LOW: 1.80 V
These default levels are set once and can be adjusted afterwards by
moving the entry focus to the value as normal.
Voltage/Current Mode (mV/V/mA/A)

Select an output source impedance of 50

or 1 k
Ω
.

Load Impedance Parameter (50.0
Ω
)
Adjust the load impedance value expected at the output to compensate
for non-50
Ω
loads. The displayed level parameters are then calculated
using this value and therefore represent the levels at a non-50
Ω
static
load.
