Remote command:
Time / Distance
"Time" and "Distance" switch over between the x-axis scaling in time units or distance
units.
The interpretation of time and distance depends on the measurement type. For reflection
measurements, the time axis represents the propagation time of a signal from the source
to the DUT and back. For transmission measurement, it represents the propagation time
from the source through the device to the receiver.
The distance calculation is consistent with this picture:
●
For reflection measurements (S-parameters S
ii
or ratios with equal port indices) the
distance between the source and the DUT is half the propagation time multiplied by
the velocity of light in the vacuum times the velocity factor of the receiving port defined
via "OFFSET EMBED > Offset" (
Distance = 1/2 * <Time> * c
0
* <Velocity Factor>
).
The factor 1/2 accounts for the return trip from the DUT to the receiver.
●
For transmission measurements, the distance is calculated as the propagation time
times the velocity of light in the vacuum times the velocity factor of the receiving port
defined via "OFFSET EMBED > Offset" (
Distance = <Time> * c
0
* <Velocity Fac-
tor>
).
