Measured Data Analysis and Report Creation Tool

AQ7932 OTDR Emulation Software(Sold Separately)

AQ7932 is application software that performs analysis of trace data measured by the AQ7270 OTDR on a PC, and creates reports. The report creation wizard makes this task simple. AQ7270 OTDR data can be easily loaded onto a PC using USB memory or the communication interface.

- Trace Analysis
You can edit event search conditions, approximate curve line settings, and other conditions, and then repeat the analysis. And
now it is even easier to operate; simply click the function icon with the mouse.

- Analysis  Functions
Display up to eight traces on screen and perform a variety of different analyses including: multi trace analysis, differential trace
analysis for comparing recent waveforms with old ones, and 2 way trace analysis function for analyzing average values of data
measured from both directions in the optical fiber.

- Creating Reports
Compiles trace and measured values from trace files and creates a report. Reports can also be created in Excel or CSV
format. Reports are easy to create by following the step-by-step instructions in the report wizard.
