A5 – see Section VII if necessary for alternate adjustment locations. The Parallel Poll may consist of three types of operations: The rms keys cannot be used to enter offset. The following backdating information is organized by service group with applicable information placed together for mahual reference.

Connect a if, pF load at either end in parallel with the line.

External Reference Phase Lock Loop The oscilloscope should display two square waves, approximately five divisions peak-to- peak, d. Basic Block Diagram of Control 8-G-l. Also included is information on recommended modifications for improvements to earlier instruments.

Set the A to the following frequencies and verify Hewlett Packard A Shown. To avoid electrical shock, make sure the power cordis disconnected before removing the instrument cover. Universal and Addressed Commands.

No adjustments can be made. Digital voltmeter reading should be Some instruments have been designed to enter the Remote mode msnual soon as REN is true. Connect the A output through a ohm feedthru termination -hp- 1IC to the oscilloscope input input dc coupledor set the A input switch to 50 ohms.


Connect a dc digital voltmeter to A rear panel X Drive output.

The preceding range of instruments do not have R The output level is a nominal 0 dBm into 50 ohms. Printed circuit assemblies are listed in Table It calls attention to procedure, practice, condition or the like, which is essential to highlight.

View Cart My Account. Accuracy of DC Offset into 50 ohms: The mankal are valid programming strings data messages for the A: Al correspondence with Hewlett-Packard concerning this instrument should include the complete serial number.

When the ac signal is removed in this way, the instrument automatically displays dc offset, and the dc offset entry key light comes on. If no error occurred, the code returned is 0, When more than one error has occurred, only the code for the first error will be returned. Test Equipment Required for Expand the oscilloscope vertical display and adjust controls so that the overshoot can be measured.

Two HP A units can be phase locked together for dual phase output applications. If not, decrease padding capacitor A14C using the capacitors shown in Table In order to keep the manual up to date, one should periodically request the most recent supplement which is available from the nearest HP Sales and Service Office.

For example, if the desired frequency is In each case, allow the thermal converter several seconds to majual.

Test Frequency Function Minimum Maximum m Determine the value of a 0 using the equation: Component replacement and internal adjustments must be made by qualified maintenance personnel. Earlier versions of the A, however, may differ in design from the instruments this revision documents directly. h

Set the analyzer controls as follows: In any correspondence, refer to the instrument by model number and full serial number. This procedure tests the sine wave output for spurious signals which may be generated by the A frequency synthesis circuits.

Set the A frequency to 5. Signature Analysis Test Included are initial inspection procedures, power and grounding requirements, line voltage selection, environmental requirements, installation instructions, HP—IB connection procedure, and instructions for repackaging for shipment.

Meta Messages Block Diagrammed. Frequency sweep of all functions is provided in linear or log sweep, at sweep times of 10 milliseconds to The type of power cable shipped with each instrument depends on the country of destination.

When this sheet is filled out, it will provide a summary of the system capabilities. Enter 5 V offset in the A. First determine the value of a ; using the following equation: Maximum and minimum amplitudes are shown in Table The digital voltmeter reading should be —4, to —4.

It should be manial The specification in Table is: If the shipping container or cushioning material is damaged, it should be kept until the contents of the shipment have been checked for completeness and the instrument has been checked mechanically and electrically.
