Riser-Bond Instruments has taken waveform storage to a higher level. Model 1205T's exclusive SUPER-STORETM is the ultimate in waveform storage, viewing, and comparison.

Competitive TDRs store only a screen snapshot of the cable under test. Model 1205T stores all on-screen and off-screen cable data, for viewing at all gain settings.

Recall the waveform on Model 1205T or upload to a PC for post-storage analysis, comparison, manipulation, and archiving. Or, download the waveform directly to an external printer.

WAVE-VIEWTM for Windows® software is included free of charge, creating a virtual TDR on your PC. Try that with any other TDR!
