Sure looks like it from what you posted. There've been discussions here -- it comes up every so often -- how to to do averaging on a SA. Without knowing how they did, it's hard to say for sure, but it looks like you are close enough to hit the target with a hand grenade anyway. But are you sure it doesn't say 30 *Hz*? Narrowing the bandwidth 'way down is a method used to get averaging on a SA. (I will speculate that someone might have "learned" to -- incorrectly -- use video averaging in dB mode then increase BW to compensate for the error that causes.)
