Anritsu displayed its innovative Capture & Playback feature for the MS2830A and MS269xA series Spectrum/Signal Analyzers at IWCE, held on March 18-19 in Las Vegas. The Capture & Playback feature allows manufacturers of chipsets and public safety radios to use real-world signals in the laboratory and production line for greater accuracy and more thorough verification of designs before the radios are used in mission critical environments. Capture & Playback allows design and manufacturing engineers to conveniently capture up to 100 MHz of spectrum with the push of a button and play it back at any designated frequency and amplitude.
This feature enables engineers to easily transfer waveform data acquired using the signal analyzer to the integrated signal generator, where the signal can be reproduced with the stability and repeatability of a laboratory-grade instrument. After the waveform data has been transferred to the signal generator, the amplitude and frequency can be tuned freely to determine performance margins on the device under test (DUT). It also replaces a complex process that would otherwise require multiple instruments, file transfers and data conversions.
The MS2830A and MS269xA can be used by engineers for validation, characterization, electromagnetic compatibility and production testing of devices and components with Capture & Playback. It can be used to conduct spot performance checks on public safety radios, troubleshoot elusive receiver blocking problems experienced in the field, and its accuracy and repeatability can yield greater confidence that public safety radios will operate as planned in their intended environments. Capture & Playback delivers laboratory-grade results from real-world signals, combines the benefits of field testing and simulation without the drawbacks of each. Anritsu’s MS2830A and MS269x Spectrum/Signal Analyzers with optional built-in vector signal generation are flexible, compact, single-instrument solutions for testing transmitters and receivers. They offer up to 125 MHz signal analysis bandwidth at frequencies up to 43 GHz, 120 MHz bandwidth vector signal generation at frequencies up to 6 GHz, and support for numerous wireless interfaces. The 100 Msamples of signal analyzer memory translates to a 50s capture duration for a 1 MHz span and 5s for a 10 MHz span, enabling the simple capture and playback of complex sequences of signals.
