measuring FM deviation / occupied band width

$

0

no mod monitors available to me so I did a little experiment with what I had

on hand to check my FM occupied bandwidth.

this is what I did.

Tools:Atenn AT5005 spec analyzerCarver TX11b with aftermarket IF TapRG 58 with BNC connectors

hookup:Spec An set to 88.9 (my operating frequency) set for 0.200 scan width andvideo filter enabled connected via RG58 to the IF out of the TX11b which wasalso set to 88.9

is this the proper setup and settings to read my occupied bandwidth for FM?

it looked to me that I was slightly under 200khz total occupied bandwidth ifI did everything right.
