CALCulate<[1]..8>:MATH[:EXPRession] <string>
Selects a measurement function that processes one sensor or two together. The result
of this calculation is made available as a measured value and can be queried with
FETch<[1]..8>? or CALCulate<[1]..8>:DATA?
.
The <string> parameter may assume the values given in the following table, n and m
may assume 1, 2, 3 and 4. A sensor must be connected to the respective channel.
Error messages:
-151 "Invalid string data": An invalid <string> parameter was transmitted.
string Meaning
"(SENS1)"
The calculate block outputs the measured value of sensor A.
"(SENS2)"
The calculate block outputs the measured value of sensor B.
"(SENS3)"
The calculate block outputs the measured value of sensor C.
"(SENS4)"
The calculate block outputs the measured value of sensor D.
"(SENSn-SENSm)"
The calculate block outputs the difference between the measured values of
sensor n and sensor m.
"(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.

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)"
If sensor n measures the forward power of a wave and sensor m the reflec-
ted/transmitted power, the calculate block outputs the reflection coefficient/
transmission factor of a DUT. The output unit is set to percent (UNIT:RAT
PCT
).
"RLOS(SENSn,SENSm)"
If sensor n measures the forward power of a wave and sensor m the reflec-
ted/transmitted power, the calculate block outputs the return loss/transmis-
sion loss of a DUT. This function principally supplies the same result as the
(SENSn/SENSm) function. The difference is that the output unit is automati-
cally set to dB.
(UNIT:RAT DB
).
