The Tektronix AM70 is a programmable digital audio analyzer and generator. It features analog and digital audio outputs as well as digital audio inputs. In addition, the AM70 features an internal loudspeaker and headphone output to permit users to perform confidence monitoring of digital audio signals.

Operating Modes

The AM70 has three modes of operation. Generator Mode permits the AM70 to act as a source of analog and digital test signals. Test signals are generated by direct digital synthesis using either the internal clock of the AM70 or an external digital audio signal. This permits the output signals of the instrument to be synchronized with external digital audio signals.

Monitor Mode permits a user to monitor important aspects of a digital audio signal. By connecting an optical or electronic digital audio signal, a user can monitor the states of validity, parity, channel status, and user bits. An internal DA converter permits the user to listen to the digital audio signal through an internal speaker with headphones. These signals may also be routed to the balanced analog outputs. Furthermore, the digital input signal can be echoed on the optical or electronic digital audio outputs.

Modify Mode permits the AM70 to be installed in-line with a digital audio signal to perform real-time editing of the digital audio data. This capability includes editing of the status and user bytes, validity and parity bits, as well as the length of audio samples and the exchange of left and right audio samples.

Simplified menus and keyboard controls make the AM70 easy to use and program. AM70 users can define four "Quick Keys" for each operating mode, thus simplifying routine calibration and troubleshooting tasks.
