Resistor string value calculator
for constructing stepped attenuators.

(Click here for a shunt attenuator calculator)

Potential divider resistors Rx and Ry as shown:
(Note that Rx and Ry are made up by the string of resistors in the chain)

Enter total value of attenuator : ohms. (= Rx + Ry)
Enter number of steps(24 max):

Enter attenuation required for each step:
-- Step 01 : dB. -- Step 02 : dB. -- Step 03 : dB.
-- Step 04 : dB. -- Step 05 : dB. -- Step 06 : dB.
-- Step 07 : dB. -- Step 08 : dB. -- Step 09 : dB.
-- Step 10 : dB. -- Step 11 : dB. -- Step 12 : dB.
-- Step 13 : dB. -- Step 14 : dB. -- Step 15 : dB.
-- Step 16 : dB. -- Step 17 : dB. -- Step 18 : dB.
-- Step 19 : dB. -- Step 20 : dB. -- Step 21 : dB.
-- Step 22 : dB. -- Step 23 : dB. -- Step 24 : dB.
