The output impedance can be either or 50R. These procedures do not check whether or not all Audio Analyzer program codes are being properly interpreted and executed by the instrument, however, if the front-panel operation is good, the program codes, in all likelihood will be correctly implemented.
Hewlett-Packard further certifies that its calibration measurements are traceable to the United States National Bureau of Standards, to the extent allowed by the Bureau’s calibration facility, and to the calibration facilities of other International Standards Organization members. Unless it is set to Listen Only, the Audio Analyzer sends data messages or the Status Byte message if enabled when addressed to talk. After installation and calibration, performance will be identical to the HP B Option programmingg For dc level measurements, the Ranging RMS Detector also monitors the ac 8903v if there is one and lowers the gain of the input path if the signal will overload the input amplifiers; otherwise, the gain of the input path is determined by measuring the dc level.
When either of the trigger codes T2 or T3 is received by the Audio Analyzer, a measurement is immediately initiated. Manuaal is fast enough for applications such as unsquelching pagers see Figure As a consequence of this, mxnual Audio Analyzer must interrupt the current measurement cycle to determine whether any action in response to these commands is necessary.
The right display should show between 12 8930b 19 dB.
8903B Operation and Calibration Manual
The dc voltmeter measures both dc signals. NOTE The “- – – -“display indicates a transient condition. The range of the selectable load resistance in ohms is an integer value from 1 to Unscrew the Pozidriv screw at the center of the rear edge of the top cover. The Audio Analyzer powers up displaying ac level in linear units maual or 890b.
I cant give a full list of interfaces that are compatible with the VEE and Pete’s software The oscilloscope should show a 1 kHz 1 ms period sine wave of approximately 7 Vpp. The following list includes the name and option numbers for each available filter. Service Errors Service-related manuao. This is useful to measure a power amplifier, to see how it’s distortion rises with increasing power. Instruments Covered By Manual. This display shows the general error display format.
Adjust the frequency of the source to approximately Hz until the right display probramming -3 dB. Leakage currents at these line settings may exceed 3. The output from the filter is the distortion and noise of the signal. The two front-panel FLOAT switches determine whether the input and output circuitry are floating or single-ended.
The notch filter removes the fundamental from the input signal. If all the internal address switches and the Data Output Format. DDDD mV range 4. Thus, the instrument can set an incorrect input range if a large common-mode signal is present.
HP A and B analyzers are plentiful and relatively inexpensive on the used market. The power cord is connected to internal capacitors that my remain live for 5 seconds after disconnecting the plug from its power supply. If you set it very low, there may not be enough output from the amp to get a distortion reading. This permits measurements in the presence of large amounts of impurities and assures that the fundamental is tuned out. The low-pass filters are inserted after the notch filter.
If full output attenuation is not selected, then noise is not held to a minimum level. It’s all a simple matter of software. Rear-panel features are shown in Figure Rear Panel Features 1.
After this the only other product needed was the VEE 5. Intentional interruption is prohibited.

This is useful for looking at amplifiers and especially transformers. The input signal is ac coupled for all measurement modes except dc level. The Audio Analyzer displays the ratio of the input voltages as the internal source is switched on ypib Off.
The error messages can also be selectively disabled to prevent unwanted error interrupts to the HP-IB bus controller.
The right display should show 85 dB or more. Only the controller can return the Audio Analyzer to local front-panel control.
True rms or rms calibrated average. Receiving the Clear Message. HP VEE runtime package free – see below.
