An instrument manufactured after the printing of this manual may differ in some respect from the information in this manual. It is recommended that the upper and lower amplitude limits selected be hl the same range because irregularities in the sweep will occur if the attenuator relays are switched. Add microprocessor control and Hewlett-Packard Interface Bus HP-IB operation and the result is more performance, flexibility and versatility on the bench or in automatic test systems than previously available, and at a lower cost. Negative Slope Ramp Frequency. Figure is a diagram of the interface connections and bus structure. Write the program in flowchart or algorithm form.

Direct current power line. Set the counter to average periods. HP A Service Manual download, schematics, eeprom, repair info for electronics experts Expand the oscilloscope vertical display and adjust controls so that the overshoot can be measured.
Where maintenance can be performed without power applied, the power should be removed. Set the amplitude to 40Vp-p and the frequency to Hz. Device Dependent — 1. Set frequency to 99,9 Hz and function to square. C33 was added to reduce Fractional N spurs at 20MHz. Adjust the spectrum analyzer as follows: Refer to Table for a listing of the A PC assemblies and their current May revision, The A address is normally set at the factory to: The digital voltmeter reading should be These keys select the output signal function or dc only see Paragraph Enable Signals For Function A Change A function to negative slope ramp.
No other device dependent data communications are permitted on the bus until the entire A program string has been accepted and all but the last character processed. Table servuce the engineering changes that have brought A21 to its current revision. See List of Abbreviations in Table This is the same digit that would be used to manuaal the parameter to that state.
Equipment required to maintain the Model A is listed in Table This group includes the numeric data keys, the data value suffix keys, the Store and Recall command keys, and the entry Clear key.
Simplified Illustration of Ramp A and Below. If either Option or is mabual, the corresponding kit is shipped with the instrument. Note that the part number for A3U16 in this earlier design was Hewlett-Packard uses a two-section serial number consisting of a four-digit prefix and a five-digit suffix.
Connect the A signal output to the electronic counter channel A input with a 50 Q load. Nanual positive peak voltage of attenuated waveform on voltmeter. Some instruments have been designed to enter the Remote mode as soon as REN is true. The A can be set up manually to the optimum parameters needed for the test to be performed, then the calculator can interrogate the A to determine and record these parameters.
If the dc voltage measured in the MHz range is out of tolerance, increase or decrease the value of A14C as necessary, using the values shown in Table Related Posts.
