Outstanding performance and flexibility
The B Series APx525 ships with two channels of analog I/O and our Digital Interface Option (DIO) with AES/ SPDIF digital inputs and outputs, and includes ASIO capability. If you need more than that, APx525 is ready with a full range of choices, from additional channels of analog to a chip-level digital serial interface (DSIO), HDMI+ARC, PDM (Pulse Density Modulation) or Bluetooth® wireless technology with built-in radio.
Need higher analog performance? With the BW52 enhanced analog bandwidth option installed, you can make a million-point FFT spectrum acquisition at 24 bits, across a bandwidth of DC to over 1 MHz on two channels. And with the AG52 enhanced analog generator option, typical system THD+N is as low as –110 dB.
The B Series APx526 is a four channel version for those who require additional analog input channels.
The power of APx measurement software
Across all measurements, the APx UI is fast and intuitive. Just click to select a measurement, then click to add a filter. Drag limits to set pass/fail points right on the results graph. Eortlessly specify computations for derived results. The APx generator can output steady tones, twin tones, sweeps, chirps, multitones or play WAV files as arbitrary waveforms
APxDigital Options
APx B Series audio analyzers offer world-class performance and flexibility. Our modular systems allow you to select the interfaces and options that make sense for the work you do, covering the widest range of digital I/O in the industry. Select models support jitter generation and analysis when installed in AMCconfigured APx analyzers.
- Bluetooth® – supports A2DP, AVRCP, HFP and HSP profiles
- PDM – one-bit audio generation & analysis (including PSRR and jitter*)
- PDM 16 – Simultaneous 16-channel PDM signal acquisition
- Digital Serial – I2S, TDM, multi-line support (including jitter*)
- Advanced Digital – AES/SPDIF/Optical (including jitter*)
- HDMI+ARC – source, sink & monitor (including metadata)
Picture below shows B Series APx platform incorporates a modular architecture enabling configuration for a variety of digital I/O options.
