string Meaning
"(SENSn+SENSm)" The calculate block outputs the sum of the measured values of sensor n and
sensor m.
"(SENSn /SENSm)" The calculate block outputs the quotient of the values measured by sensor n
and m.
"SWR(SENSn,SENSm)"
SENSn SENSm
SENSn SENSm
/ 1
/ 1


If sensor n measures the forward power of a wave and sensor m the reflected
power, the calculate block outputs the standing wave ratio of this wave. The
output unit is set to percent (
UNIT:RAT PCT
).
"REFL(SENSn,SENSm)"
SENSn SENSm /
If sensor n measures the forward power of a wave and sensor m the reflected/
transmitted power, the calculate block outputs the reflection coefficient/trans-
mission factor of a DUT. The output unit is set to percent (
UNIT:RAT PCT
).
"RLOS(SENSn,SENSm)"
SENSn SENSm / log 20
10

If sensor n measures the forward power of a wave and sensor m the reflected/
transmitted power, the calculate block outputs the return loss/transmission loss
of a DUT. This function principally supplies the same result as the (SENSn/
SENSm) function. The difference is that the output unit is automatically set to
dB.
(
UNIT:RAT DB
).
