The Portable One family of audio analysers from Audio Precision is now available exclusively in the UK from TTi (Thurlby Thandar Instruments).
Suitable for broadcast and communications or bench and production use, Portable One offers a complete easy-to-use audio test-set housed in a rugged case.
Twelve different measurement functions are selectable with the push of a button, making it a comprehensive but user-friendly instrument, says the company.
The first product in the family is Portable One Plus Access.
This is designed for maintenance, repair and design activities in the field, studio, service organisation or laboratory.
It is a two-channel (stereo) unit that generates sine and square waves, and measures level (on both channels simultaneously), noise, THD + N and SINAD.
It also measures frequency, phase, amplitude ratio, crosstalk, wow and flutter, input AC resistance and AC mains parameters.
The analyser can store 30 instrument set-ups including data, provides frequency and amplitude sweeping, and has graphing and printout capability.
Hard copy may be graphical data, tabular data, or both.
The printer output will drive laser, inkjet or dot-matrix printers.
The second product, the Portable One Dual Domain, adds complete digital audio and AES/EBU/IEC serial interface generation and measurement capability to 96kHz.
It is a dual-domain instrument, in that signals are generated and measured in their native domain, analogue or digital.
The analyser also includes separate and independent digital audio and jitter generators and analysers.
The instrument generates digital-domain audio signals and measures digital embedded audio parameters including level, THD+N, IMD (optional), phase, frequency, ratio and crosstalk.
It generates jitter and measures jitter and sample rate, and reads status bits and tests for interface errors.
An inter-modulation distortion signal-generation and measurement option complying with SMPTE and DIN standards is available for both products.
A GPIB interface allowing control of the instrument in an automatic test environment is supplied as standard.
Both versions come with a range of standard filters, and a range of optional filters is also available.
Other options include a switching amplifier measurement filter, rack-mount kit, various interconnection cables and test discs (CBS, NAB, Philips and JAS).
