Reply To: Yet another sound guy with an SA44B and a question.

CH,
The software-based image rejection does limit the usefulness of the SA44B. For scans wider than 200 kHz, any time there is energy 21.4 MHz above, and 21.4 MHz below, the frequency being scanned, a spur will show up there. Narrower scans (200 kHz or below) have the same issue, but at different offset frequencies.
All of this is fixed in a product like the BB60D, with excellent hardware-based image rejection.
