III. Attenuation Repeatability Test 

Use the same equipment, test setup and instrument settings as used 
for the Attenuation Accuracy test (see the appropriate Total 
Insertion Loss Test Setup 2).

1. Set the Agilent 8156A attenuation to 1 dB and press D

on the power meter.

2. Set the Agilent 8156A attenuation to any other value (e.g. 

0.00 dB), wait until it settles at this value (The time taken to 
change depends on the size of the attenuation factor change, and 
is in the range 20 to 400ms (typical value is 200ms)). Then 
change the attenuation back to the previous value. Note the 
deviation (dB) in the Test Record and check that it is within 

±

0.01 dB.
