W REF
MTX 3283
Adjustment of the reference resistance value (W REF) between 1 Ω and
10,000 Ω for resistive power measurements:
The calculation performed is: (voltage measured)
2
/ W REF (unit W)
(current measured)
2
∗ W REF (unit W)
The adjustment procedure is the same as for the dBm reference resistance.
 Default value 50 Ω
ΩΩ
Ω .
W REF is used to calculate the resistive power (W) with
REF = W REF and to calculate the power (V ∗ A) when V (Ref) = W REF
Initialization of the
values
 Default values
The parameters of the configuration can be reinitialized to the default settings
in a single operation:
• Opening of the Configuration menu with the key.
• Selection of the "Default init"
function using the keys .
• Validation of initialization
using the
key.
Loading of the default values is confirmed by the following message:
