Table 14-1: <expression> parameter
<expression> Description
"(SENS1)" Measured value of sensor A
"(SENS2)" Measured value of sensor B
"(SENS3)" Measured value of sensor C
"(SENS4)" Measured value of sensor D
"(SENSn-SENSm)" Difference between the measured values of sensor n and sensor m
"(SENSn+SENSm)" Sum of the values measured by sensor n and sensor m
"(SENSn /SENSm)" Quotient of the values measured by sensor n and m
"SWR(SENSn,SENSm)" Standing wave ratio. The output unit is set to percent (
UNIT:RAT PCT
).
SENSn SENSm
SENSn SENSm
/ 1
/ 1


Sensor n measures the forward power of a wave, sensor m measures the
reflected power.
"REFL(SENSn,SENSm)" Reflection coefficient/transmission factor of a DUT. The output unit is set to
percent (
UNIT:RAT PCT
).
SENSn SENSm /
Sensor n measures the forward power of a wave, sensor m measures the
reflected/transmitted power.
"RLOS(SENSn,SENSm)" Return loss/transmission loss of a DUT. The output unit is set to dB
(
UNIT:RAT DB
).
This function principally supplies the same result as
"SENSn/SENSm"
. The
difference is that the output unit is automatically set to dB.
SENSn SENSm / log 20


Sensor n measures the forward power of a wave, sensor m measures the
reflected/transmitted power.
With n and m = 1, 2, 3 or 4

Measurement channel
Parameters:
<expression> See Table 14-1 . The unit is set by
UNIT<Measurement>:
POWer[:VALue]
or
UNIT<Measurement>:POWer:RATio
.
*RST: Depends on the selected channel.
Default unit: Depends on <expression> and the set unit.
Manual operation: See "Channel Calculation Function" on page 61
