SOFTWARE OPTIONS APx ANALYZERS APx500 MEASUREMENT SOFTWARE APx500 software options provide measurements and functionality beyond the core set of capabilities standard for each APx analyzer. A variety of options Software options are enabled by one or more “iButtons” that mount on the rear of the APx instrument. Each iButton enables a particular feature or set of features, and can be moved from analyzer to analyzer as needed. APx515 Standard measurements included in the APx515 are: Level & Gain Frequency Response THD+N Signal-to-Noise Ratio Noise Crosstalk Interchannel Phase DC Level Frequency Measurement Measurement Recorder Stepped Level Sweep Stepped Frequency Sweep Compare Encoded Bitstream Level Ratio CMRR SINAD Pass/Fail Scope Monitor DC Level Sweep Q-peak Noise Input Sample Rate Advanced measurements available for the APx515 via software options are shown below: APx Option Acoustic Response Measurement Advanced Measurement Library (includes FFT Spectrum Monitor) ASIO Direct Connectivity High Speed Test APx525, 526, 582, 585, 586 and 555 Standard and advanced measurements are included in all models.
