8903B HPIB PROGRAMMING MANUAL PDF

Brakinos The Detailed ;rogramming Instructions are designed so that both casual and sophisticated users can rapidly find at one location all the information needed to apply the instrument to the task at hand. Few people have hearing that good, but the term is a convenient one to describe sub-RF frequencies encountered in electronics. The range of the selectable load resistance in ohms is an integer value from 1 b However, when the signal is a complex waveform, or when significant noise is present, the averageresponding detector reading can be in error. Remove the two manul feet from the rear of the top cover by removing the panhead Pozidriv screw within each foot.

Remove the two manul feet from the rear of the top cover by removing the panhead Pozidriv screw within each foot. The audio spectrum analyzer method, however, requires a fairly expensive instrument and some mathematical manipulation.

Once the data measurement results are read onto the bus, the Audio Analyzer reverts to the Hold mode. The local lockout mode prevents loss of data or system control due to someone accidentally pressing front-panel keys.

W h e n handling or servicing equipment containing static sensitive devices, adequate precautions must be taken to prevent device damage or destruction. For more detailed information relating to programmable control of the Audio Analyzer, refer to Remote Operation, Hewlett-Packard Interface Bw in Section 3 of this manual.

In addition, the Audio Analyzer may be triggered via data messages to make measurements at a particular time. Apart from attentive b to a hi-fi system, the most intuitive way of analyzing an electrical signal in the audio range is visually with an oscilloscope. Mating Connectors Interface Connector. The output detector converts the residual noise distortion to dc. The Quasi-peak Detector, when used with the optional CCIR weighting Filter gives signal-to-noise measurement results which more accurately correlates with perceived signal-to-noise ratios.

High THD at high frequency is a result of slew rate limiting, among other things. Measurement Display Annunciators indicate the measurement result units. AC level measurements can be displayed in volts, dBm into R, or watts.

Pure signals in manusl sound monotonous. FLOAT switch provides floating input when required. For example, on the Case 1 graph, for a differential input voltage level of lV, the maximum commonmode input voltage level is 2. To avoid electrical shock,do not perform any servicing unless you are qualified to do so. Use a dry cloth or one slightly dampened with water to clean the external case parts. Rejection of squelch tones up to Hz is greater than 40 dB. Impurities are not always undesirable.

When installing the product in a cabinet, the convection into and out of the product must not be restricted. This number represents the talk and listen address characters which an HP-IB controller is capable of generating. I t calls attention to a procedure, practice, or hplb like, which, if not correctly performed or adhered to, could result in personal injury.

If you operate or service instruments with different proggamming prefixes, we strongly recommend that you join this service immediately to ensure that your manual is kept current. Related Posts.

The SPCL key light should be lit. Trigger with Settling is the trigger type executed when a Trigger message is received via the bus. Performance Test 3 Distortion and Noise. When the Abort message is received, the Audio Analyzer becomes unaddressed and stops talking or listening. Reinstall the top cover programmong reversing the procedure in step c above. How, then, can you be sure that the result is a valid measurement of distortion? Selecting programmihg Service Request Condition.

Goltisida Weighting filters which meet most international standards are available. When this signal is measured by a distortion analyzer, an error results from the first part of the measurement measuring the input level because the input level is not quite the same as the level of the fundamental. This error code indicates that although the required calculation is within the capability of the instrument, the result of the calculation exceeds the display capabilities. This makes measurements such as frequency response or complete distortion characterization simple to perform. All of the instructions for the FR plot apply here as well. To protect the active circuits that follow, the Over-Voltage Protection circuit opens whenever its input exceeds 15V.
