Abstract: A setup is presented for measuring ATSC 8-VSB receiver blocker performance that overcomes out-of-band noise limitations of the Rohde & Schwarz SFQ TV Test Transmitter. The setup involves close-in filtering with a SAW filter at 44MHz, mixing up to a fixed, desired RF frequency, and filtering further-out noise with a cavity bandpass filter. Blocker requirements in the ATSC A/74 standard are discussed. The SFQ out-of-band noise is shown before and after the two filter stages
