Tektronix 760A Audio Scope
With this stereo audio monitor, the audio engineer can analyze a pattern display of the stereo audio signal. This display, along with a high resolution bar graph, provides accurate monitoring and measurement capabilities. Used in both operation and setup, the instrument provides immediate feed-back of the audio signal for creative or technical correction. With the appropriate test signals, the unit can also be used for accurate phase and amplitude measurements.
On the CRT and adjacent bar graph, you can observe amplitude information, stereo separation, and phase correlation between the left and right channels. Also of great importance, you can see monaural amplitudes resulting from the stereo channels.
Your choice of automatic or manual gain control provides flexible control of the pattern size. With no input signal, the display will dim to prolong CRT life.
Two calibrated bars are dedicated to the left and right channels. The input to a third bar is selectable from Sum, Difference (both internally derived) and an Auxiliary input on the rear panel. These bars give the operator even greater resolution for setting line-up level when the EXPAND SCALE push button is depressed. This increases resolution around the line-up point of the bars. A selectable three second PEAK HOLD control makes level monitoring easier than ever.
The 760A is ideally suited for use in editing suites, master control, transmission and any other locations where monitoring the stereo audio signal is a must.
