The LFM-39A is a wow and flutter/drift meter designed primarily for testing and repair of audio tape decks, turntables,VCRs and other record/playback equipment. Using reference test records or optional test tapes, this instrument enables quick verification of spec and isolation of the trouble area to the capstan, clutch, motor or belt, greatly reducing repair time. Measurements to JIS rms, CCIR, and DIN quasi-peak or NAB mean standards are front-panel selectable with DIN and NAB available as options. The four measurement modes include combined W&F unweighted, W&F WTD i.e. weighted and separate wow or flutter unweighted. This shows the different amounts of errors attributable to wow or flutter. The analog drift meter indicates both long term tape speed drift and short term variations which are missed when using gated frequency counters.
The LFM-39A is a precision instrument offering 0.25% drift measurement accuracy and 5% full-scale wow and flutter measurement accuracy. |
