The Portable Bang Unit PBU-1 is a small handy battery operated unit which produces very accurate sound impulses for testing microphone sensitivity, and for adjustment of the electronic circuits of AS-100 Miss Distance Indicators (MDIs).

The PBU-1 consists of two parts, i.e. the Portable Bang Unit PBU-1 and the Bang Box BB-1/C. The BB-1/C is connected via a 2.5 m long cable to the PBU-1.

The sound impulse from the compressor type loudspeaker has a frequency of approx. 1 Hz is fed through a mouthpiece. Each MDI type has its own type of mouth piece. The PBU-1 is used to test and adjust all types of AS-100 MDIs.

The PBU-1 has a built in rechargeable 12 V battery.

The battery is charged with the Battery Charger BC-7/2


For accurate operation the ambient temperature should be within 23 ± 5° C. If the PBU-1 is used outside the specified temperature range the PBU-1 is regarded as a GO or NO GO test instrument.

The storage temperature is -35 +70° C. Avoid humid conditions, which may cause condensation.
