Tektronix DA 4084 Distortion Analyzer
DA 4084 Programmable Distortion Analyzer with an operations manual.
This instrument is in excellent physical and electrical condition. The DA4084 provides fully automated measurement of level and total harmonic distortion plus noise (THD+N). Automatic measurement means that once the mode is selected and the test signal is applied, the operator simply reads the accurate result on a 3-digit display. Functions such as level setting, tuning, and nulling are fully automatic.
The DA4084 provides dB-ratio measurements referenced either to 774.6 mV (1mW in 600 ohms) or to a user applied signal. The 0 dB reference memory stores selected level, and all subsequent measurements are referenced to it. The user can choose either rue-rms or average response. While true-rms is generally more accurate, the averaging feature is convenient for comparison of new data with data taken on older instruments where averaging was the only mode available. The fundamental frequency range is 10 Hz to 100 kHz with harmonic measurements to 300 kHz. Any one of four built in frequency-weighting filters can be switched into the signal paths for input signal preconditioning. External filters can be simply connected for for special applications such as stereo pilot tone rejection, rejection of continuous tone squelch signals in mobile radio systems, or for selection of individual harmonics instead of total harmonic distortion measurements. An input monitor connector and Function Output connector permit oscilloscope display of the input signal or the filtered signal input used in THD+N measurement.
