automated audio test system advantages tegam sg 5010 and aa 5001 programmable i nstruments in a computer controlled test system will make critical audio measurements consistently, accurately, and in two to four seconds each. even complex tests can be made by non-technically-skilled operators since the procedures are controlled by software in the controller. and, permanent graphic or tabular records of test results can be produced at very low cost. an sg 5010/aa 5001 based system will automatically perform such industry standard tests as harmonic distortion to ihf a202, intermodulation distortion to smpte th 22.51, din 45403, iec 268.3, and ihf a202, frequency response to ihf a202, and noise or signal-to-noise ratio to ihf a202 (??weighting filter complies with ansi specification s1.4 and iec specification 179 for sound level meters). with the option 02 capability of the aa 5001, noise measurements may be made to ccir 468-2 and din 45405 standards. the sg 5010 also generates the burst signal necessary for dynamic headroom tests per ihf a202. a basic automated system consists of the sg 5010 programmable oscillator, the aa 5001 programmable distortion analyzer, and an ieee 488 controller. frequency counters, signal switchers, interface devices, disc storage, and hard copy units or plotters may be optionally added to the system. sg 5010 / aa 5001 programmable audio test system automated audio test system advantages fast, accurate, repeatable measurements. lower required operator skill. automatic, low-cost documentation of test results in graphic or tabular form. instrument performance features extremely low residual noise and distortion permit measurements on top-grade professional and consumer audio equipment. performs all standard audio tests thd, imd (smpte, din, ccif difference tone), gain/loss, signal- to-noise ratio. analyzer input fully balanced, oscillator output balanced or unbalanced, floating or grounded, 50/150/600 to match all types of audio equlpment. automatic swept measurements possible without ieee-488 controller. four-or-more digit synthesized frequency, 0.01% guaranteed accurate. fully programmable filter and detector selection to meet a wide variety of measurement standards. high level oscillator output to test head room, clipping thresholds of line level devices. ten non-volatile stored generator setups. generator includes burst, square wave, and amplifier modes. modular test instruments tm 500 / 5000 the global source for proven test and measurement technology. prices and specifications subject to change without notice.
selected near the upper band limit of the device under test has been shown to be a very effective and simple-to-implement test for transient or dynamic intermodulation (tim and dim). burst signals of any desired duty cycle may be generated for ihf dynamic headroom measurements and to test compressors and limiters; the between-bursts level may be selected as off or 20 db below the burst level. power measurements are made by a controller computation from a voltage measurement across a known load resistance. sinad measurements of sensitivity of fm communications receivers are a standard capability of the aa 5001 plus an appropriate rf signal generator. the sg 5010 features an amplifier mode in which an external signal can be converted to the high level, multiple impedance, balanced and floating capability of the sg 5010 output circuitry. fully program-selectable filters in the aa 5001 allow various choices of bandwidth for distortion measurements and weighting for noise measurements, or rejection of interfering signals. phase measurements can be added to the system by use of the dc 5010 universal counter-timer. gpib controller since the instruments are ieee-488 compatible, any ieee-488 controller may be used with them. software features both the sg 5010 oscillator and the aa 5001 analyzer feature very high level, english-like commands for their various modes and functions. learn mode is a standard feature, permitting instrument setups to be made at the front panel and then learned at the controller by a single keystroke. both instruments are microprocessor-based, with the distributed intelligence of the system used to simplify the controller s task by such things as a programmable settling algorithm in the analyzer and stored setups plus logarithmic or linear sweeps of frequency or amplitude in the oscillator. test result documentation audio test results are obtainable in a variety of ways. graphics of one or more measured variables versus frequency or amplitude are readily produced on the controller crt. tabular results can also be shown on the crt and duplicated in hard copy. graphic test results can also be produced even without a gpib controller if an x-y plotter or storage oscilloscope is available, due to the built-in sweep capabilities of the sg 5010 plus its ramp output and pen lift signal. tm 5000/tm 500 family as members of the tegam modular tm 5000 family of programmable general purpose instruments, these new products expand the number of systems which can be configured for a variety of applications. programmable counters, digital multimeters, power supplies, function generators, switchers, and control and sensing interface devices are available to complete systems. even many of the tm 500 instruments, although not programmable, may appropriately be added for specific test systems needs. examples include products such as the am 502 differential amplifier and a variety of sine and function generators and dc power supplies. details and specifications on these products are available from tegam. modular test instruments typical applications one ideal application for automated audio testing is the moderate-to-high volume production line for consumer and professional audio equipment. test results can be economically logged or printed for files or to be furnished to the customer. in the engineering laboratory, characterization of complex variable devices such as parametric equalizers can be greatly speeded with automatic test equipment, and a color ink-jet printer can quickly produce highly legible results. audio tape recorders and the audio channels of video tape, cassette, and disc machines may be tested with no special synchronization required, as can be earth stations and radio networks when a stepped tone signal is available. performance levels of the sg 5010/aa 5001 system are consistent with new 16-bit digital system noise and distortion levels. radio and tv broadcasting stations and networks can automate proof-of-performance tests, even running them daily at sign-on or sign-off to maintain signal quality control. highly complex devices, such as large recording consoles with multiple inputs and outputs or large audio switchers, may be impractical to test with manual techniques and truly maintainable only via automation. loudspeakers and microphones can be automatically characterized by the addition of reference transducers and pre-amplifiers to the system. swept pre-emphasis, de- emphasis, or equalized signals can be easily generated since the controller has full control over both frequency and amplitude. other measurement capabilities features and flexibility of the aa 5001 and sg 5010 permit a variety of other measurements to be easily automated. smpte-like imd measurements may be made at a variety of lower frequencies and any value of upper frequency, and at 1:1 amplitude ratios in addition to the standard 4:1 ratio. a ccif test with the frequencies tm 500 / 5000
