Table 6-8: Two-channel functions ( <source_list> = (@n),(@m); n = 1,2,3,4; m = 1,2,3,4 )
DIFFerence
SC PC

Yields the difference between the PC and SC. This means that two sensors must be
specified in <source_list>. This also applies to the following functions.
:DIFFerence:
RELative
value _ reference
SC PC

The difference between the PC and SC is divided by the reference value.
:SUM
SC PC

Yields the sum of the PC and SC. The <source_list> must therefore contain two sensors.
This also applies to the following functions.
:SUM:
RELative
value _ reference
SC PC

The sum of the PC and SC is divided by the reference value.
:RATio
SC
PC
Yields the ratio of PC to SC.
:RATio:
RELative
 
value _ reference
SC
PC
The ratio of the PC and SC is divided by the reference value.
:SWR
PC SC
PC SC
/ 1
/ 1


If the forward power of a wave is measured in the PC and the reflected power in the SC,
the measurement command yields the standing wave ratio. The output unit is set to "One"
(
UNIT:RAT O ).
:REFLection
PC SC /
If the forward power of a wave is measured in the PC and the reflected/transmitted power
in the SC, the calculate block yields the reflection coefficient/transmission factor of the
DUT. The output unit is set to "One" (
UNIT:RAT O
).
:RLOSs
PC SC / log 20
10

If the forward power of a wave is measured in the PC and the reflected or transmitted
power in the SC, the calculate block yields the return loss/transmission loss of the DUT.
This function principally yields the same result as the
:RATio
function. The only difference
is the output unit which is automatically set to dB by means of this command (
UNIT:RAT
DB
).
