This application has four calculation functions.
1) dBm to W calculator .
2) ATT value in dBm to each Resistors of circuit .
3) Resistors of circuit to ATT value .
4) Resistance connected parallel .
Picker Wheel Data setting interface is very simple for all functions .
dBm/W |
1) dBm/W
Set Numeric Wheel to power value in dBm ,
So power value in W will calculate above .
Minus dBm value is possible from 0.01µW ,
using [+/-] Wheel.
2) dB-R
dB-R |
Choose ATT tpe [Pi] or [T] ,
schematics will change Pi type or
T type .
Select ATT value with right Wheel .
Each R Value will calculate above .
3) R -dB
R -dB |
Choose ATT tpe [Pi] or [T] ,
schematics will change Pi type or
T type .
Select R1 and R2 value with
next 2 Wheels .
ATT Value will calculate above ,
and calculated total impedance in Ohm .
