The switchable loop bandwidth accommodates different satellite transponder configurations and link conditions.

Condition: Used
This Microdyne 1151-D(B)(B) Anti-Sideband Wide Angle PM Demodulator has been inspected and is in good used condition. It was pulled from a working satcom environment where it was in active use. The aluminum enclosure shows surface scratches and scuffing consistent with field service use, visible on the top and side panels. The front panel controls — including the Loop Bandwidth switch, Fine Tune dial, Loop Lock toggle, and Auto/Manual Search switch — are all present and appear intact. The rear D-Sub 25-pin (P3) connector is present and appears undamaged. Please view our photo set and contact us if you have any questions.
