TB Figure 5. The HV divider Figure B may be used with 6 feet of cable. All input and output lines are tested.

Service Group O – Power Supplies This stores all the information that is in the current program memory. Servicce Distortion relative to the amplitude of the fundamental frequency at full output on each range Fundamental Frequency No Harmonic Greater Than 0.

A list of these offices is provided at the end of this manual. Set the A function to Triangle, frequency to 9. Expand the oscilloscope vertical display and adjust controls so that the overshoot can be measured.

The minimum bandwidth for log sweep is one decade. It calls attention to a pro- WARNING I cedure, practice, condition or the like, which, if not correctly per- formed or adhered to, could result in injury or death to personnel. Polling – Polling is a means by which a controller can identify a device that needs interaction with it.

Remote control of the A by means of an HP-IB system controller is accomplished through this connector. Verify that all harmonics are at least 65dB below the fundamental. Change A function to neg ramp and CRO trigger to pos. The system controller may designate itself as either talker or listener. Set CRO as follows: Sine Amplitude Control Path. An action a device performs in response to information sent on the HP-IB.


Approved for public release; distribution is unlimited.

This procedure tests the A sine wave output for spurious signals. For example, using the A in local, the operator can determine experimentally the parameters required to perform the operation or test desired.

Return CRO sweep vernier to calibrate and set main sweep to. Test instrument parameters Harmonic distortion relative to fundamental at full output Servicw modulation Square wave Ramp retrace Frequency Sine wave Square wave Triangle Positive slope ramp Negative slope ramp Phase offset Amplitude Amplitude accuracy with no attenuation attenuator range 1 servicw 50 load no dc offset Flatness with no attenuation Change the power supply output to the following voltages and repeat Steps j through m for each.

Unrecognizable data character 9. The lines should not be separated by more than ten divisions on the display. AS – Past to Present. Maximum and minimum amplitudes are shown in Table Next, press the 0 or [Q key to move the bright digit cursor to the digit you want to modify.

Then press the O or key momentarily to increase or decrease the value of that digit by 1. The test equipment required for the Performance Tests is listed in Table Adjust the spectrum sedvice as follows: Completely define the operation s the system is required to perform. Offset with AC Function. The newer connectors are incompatible with the older cables as are the newer cables incompatible with the older connectors.



The data lines carry coded messages which represent addresses, program data, measurements, and status bytes. These bits are the same for both listen and talk addresses, and the sixth and seventh bits determine whether the address is listen 01 or talk Program examples are shown in Appendix B-3, using the -hp- Model A Calculator as the system controller. If your oscilloscope doesnot have a ohm input, use a ohm load -hp- Mode!

High Voltage Output Amplitudes Neither light on, indicates the front panel signal output is active. Protect the control panel with cardboard, d. Low at start of sweep, High at stop. Verify Vpp of 3, to 3. Output Level and Attenuator Check. The storage registers, SRQ masking, and the status byte are not affected, The horizontal arrow keys select the digit to be modified indicated by a bright digitand the vertical arrow keys increment or decrement that digit.

Set the digital voltmeter to measure dc voltage.

Printer records the results of the serial poll. Power Line Voltage Selection Model A Operation 3. Then the A can be placed in remote and its function and entry parameters interrogated.

The spectrum analyzer should display the high level odd harmonics and low level even harmonics of the 10 MHz square wave. Set the dc offset to the positive and negative voltages shown below.
